Part 1
"Mh?"
Just before Birdway was about to mention "their" name, she suddenly frowned.
Sounding annoyed, Accelerator said, "...You aren't going to put on an air of importance again, are you?"
"I have no reason to do that. ...But this is now hardly the time to be sitting here discussing this."
As Birdway spoke, she pulled her legs out from under the kotatsu and walked across the room. She was heading for the window connecting to the balcony.
"Is there something outside?" asked Kamijou. "Actually, this area has similar dorms lined up. The next dorm is only a few meters away, so you'll only be able to see a wall out that window."
"No, wait a second... If I go like this..."
Birdway went out on the balcony, and leaned out with her stomach on the railing. It seemed like she was staring beyond the gap between the buildings.
"Dammit... I was right," she said in almost a groan.
Those inside the room could see nothing outside other than that girl whose position put her skirt in a rather dangerous state.
"Is there something out there?" asked Hamazura.
Birdway finally got down from the railing, and stood on the balcony.
"'They' are here."
The three of them headed towards the balcony in shock. Kamijou tried to lean out on the balcony like Birdway had, but Accelerator kicked down the thin fireproof wall that divided the balconies between rooms.
They could now see it.
"Huh!? What the hell!?"
Hamazura was the first to yell out.
Academy City was overflowing with various lights at night, but the stars could still be seen. Something gigantic was obstructing their view of that faint light. Beyond the horizon was a huge construction of a scale never seen in real life. It was like a cumulonimbus cloud.
Birdway meaninglessly folded her narrow arms in front of her small chest.
"...I thought the science side would have brought it down at an earlier stage since Academy City was going to be dragged into this, but it seems that they were slower at dealing with this than I had anticipated. I guess the errors in his plan are having an effect."
"What did you just say?" Accelerator asked as he frowned at that line he couldn't just overlook.
Birdway nodded in an exceedingly arbitrary way.
"That thing was chasing after us from the beginning. ...Well, technically, it's chasing after that missing Imagine Breaker. That floating fortress with the mass of a dreadnought has been performing a worldwide search and following him around the clock. ...Shaking it off would have been a pain, y'know? And if we did, there was a danger of the Dawn-Colored Sunlight's trump card being analyzed. I decided that it was best to leave that troublesome thing to some troublesome people."
"So... what?" Hamazura's face paled. "Cumulonimbus clouds spread for dozens of kilometers. Are you saying that giant objet d'art is like a huge cloud made of concrete and it's going to fall on Academy City!? And you brought it here on purpose!?"
"Wait, I didn't hear anything about this!! That isn't the Star of Bethlehem, is it!?"
Even Kamijou was starting to panic, but Birdway remained completely calm. In fact, she seemed proud.
"Well, this boy was the one at the center of defeating Fiamma of the Right and ending World War III. As 'they' came about due to the war, they would want to know if he was still alive. But it takes quite a bit of effort to search the entire world. And 'they' also wanted to keep it a secret that anyone was chasing him. ...So they decided to hide a leaf in the forest. By creating a large-scale incident, they moved the world's focus to the catastrophic danger on a planetary level."
That incident was carried out in order to search for a single high school boy.
Those people were willing to risk the extinction of the human race for that purpose.
That was what magicians were.
They would use everything at their disposal for the sake of the individual while paying no heed to what it meant to the whole.
"What are we going to do...?" Kamijou groaned before he finally started shouting. "We know what they want, but we can't let them drop that asteroid-like fortress on Academy City!! How exactly are we supposed to stop them!?"
"...That's what I wanted to have Academy City do. There would have been plenty of methods while it was over the ocean, but now that it's over land, the wreckage would still fall down on the city."
"...You do have an idea, though, right?"
Kamijou shuddered, but it seemed that Birdway really wasn't stupid enough to not have a plan.
She said, "That search structure... um, I think the Anglican term was 'Radiosonde Castle'. Anyway, I have an idea as to how it is following Imagine Breaker. If we know how it works, we can use that to figure out a way to deal with it."
"So how does it work?" asked Hamazura.
Birdway meaninglessly stuck her index finger up and spun it around.
"Do you remember what I said about leylines?"
"...You said that they were one of the types of energy that could be used for magic other than the magic power created by humans. If I remember, they have to do with the Earth and its terrain," Accelerator said.
"That's right." Birdway nodded. "And Imagine Breaker negates all kinds of supernatural powers. And that includes the power circulated by the planet."
"So, his right hand is like a snowplow and that giant fortress is following the path he's created?"
"It's not that simple," Birdway responded to Accelerator's question with a sardonic grin. "Imagine Breaker works exceedingly well when it is normalizing abnormal values, but it does not show much power when dealing with something that is uniform from the start. It only carries out destruction of things that have already had their harmony taken. ...For example, he does not destroy someone's soul when he touches them, and he does not destroy the planet when he touches it. Yet those things do indeed have supernatural power flowing through them."
"...Does it really work so conveniently like that?" asked Kamijou himself.
The boy looked down at his right hand, and Birdway continued speaking in an arrogant way.
"This isn't just limited to Imagine Breaker. Natural powers like yours are often initially set to conform to the environment or situation. And the natural Gemstones are people who received esper powers via stimuli from the environment of Earth," she said in a simple manner. "To talk about the leylines... Oh, I know. I'll use the example of a snowplow you used. When Imagine Breaker scrapes away the accumulated snow, more snow quickly accumulates, preventing anyone from seeing the path. It would be more accurate to say that a cycle like that has been set up from the beginning than to say that it has to do with how much the planet can replenish the power."
"Then how the hell is that fortress tracking that Level 0?" asked Accelerator.
"'They' can't search for him normally, so 'they' set up a kind of trick."
"A trick? On the fortress?"
Kamijou looked puzzled, but Birdway's response was well beyond his expectation.
"No, on the planet."
"..."
The scale was so great that Kamijou's thoughts cut out.
But Birdway continued speaking regardless.
"The amount removed by Imagine Breaker is made to be naturally compensated for by the surroundings. 'They' have interfered with that cycle. They have made it so that a mark only Radiosonde Castle can detect will be left behind during the process of repairing the amount removed."
"How...?" asked Hamazura who still had not quite come to grips with the concept of magic. "Saying they interfered with the planet is simple enough, but how did they do it!?"
"They used feng shui. The locations of mountains and rivers change the flow of energy, so people build their palaces in the most suitable place based on that. ...Well, the opposite is also possible. If you want a certain change to occur to the energy of the leylines, you just have to systematically destroy the mountains and rivers."
It was easy to say.
For the sake of a single spell, the terrain had been blotted out somewhere on that planet. That was yet another result of the individual surpassing the whole. The magicians used everything at their disposal to carry out the goal before their eyes without giving any thought to what would come later.
Hamazura gulped.
"Would they... would they really go that far to find a single person...?"
"Compared to Radiosonde Castle, that is nothing more than a sub spell. How much energy do you think it takes to make a mass that huge float like that? Well, it's certainly not something you can pull off with gas turbines," Birdway said smoothly. "Let's get back to the topic at hand. In order to follow Imagine Breaker, 'they' have interfered with the system of the leylines running through this planet. Imagine Breaker destroys that energy, and their mark is automatically created in the process of the repairing cycle. It's like a potato or a jewel. Using that, Radiosonde Castle can accurately follow Imagine Breaker no matter where in the world he flees. Do you understand that much?"
"But that would mean there's no way to escape it!!" yelled Hamazura with his eyes wide, but Birdway was as calm as ever.
"'Their' spell may be hitching a ride on the cycle that repairs the lost power to the leylines, but it is not producing the mark at all times. 'They' have to think about the cost. It would be easiest if you just thought of it like transmitters set up at even intervals."
"..."
"Basically, they're automatically produced in the Earth at about every fifty kilometers. If Imagine Breaker is not in range, it heads for the next transmitter, but if he is in range, it is guided with even more detail. In other words..."
"...If we destroy the transmitter embedded in the ground, Radiosonde Castle will lose its ability to track me?" Kamijou muttered. "But you said that the transmitters are automatically produced at even intervals, right? If a new transmitter is created, won't Radiosonde Castle correct its course?"
"'They' are not that almighty," Birdway said halfheartedly. "It's true that 'they' systematically destroyed mountains and rivers and interfered with the workings of the planet itself, but 'they' cannot continue that forever. ...'They' are already at their limit. They cannot create a new transmitter, so we just need to destroy the one that is here now. Since the transmitters are set up in fifty-kilometer intervals, the final transmitter has likely been placed beneath Academy City. If we destroy it, Radiosonde Castle will pass right by us. After that, the members of the Anglican Church who are likely meaninglessly rushing around now will bring this to a safe conclusion."
A magical transmitter.
It was beneath Academy City.
If they could destroy it, they had a means of escape.
"..."
Kamijou looked down at his open right hand.
He then silently clenched it strongly.
Kamijou Touma was said to be at the center of all the disturbances around him, but he was not actually all that knowledgeable of the circumstances the world was in. He did not have the basis needed to actually calculate how much value there was in searching him out on such a large scale or how much meaning there was in keeping that from happening even if it meant getting Academy City involved.
But...
Kamijou understood that the results of those actions had brought danger to Academy City and to those close to him. And he knew what was necessary to avoid that danger.
What he had to do did not change.
It was the same as always.
A great conflict may have been over, but he still had to do the same things as before.
"Can I ask one question?"
"What?" said Birdway as she looked over at him.
"If I were to start running away from Academy City as fast as I could right now, what would happen with Radiosonde Castle?"
"Normally, it would alter its course and continue to follow you," the small girl responded. "But there is the issue of time. I mentioned that there was a time limit, right? If the final mark has been placed here, then Radiosonde Castle may drop on Academy City regardless of your location."
Birdway had helped create that situation, but she showed no sign of timidity about it.
"I see."
Kamijou Touma clearly clenched his right fist that time.
He ignored Index who was looking displeased.
"That's all I need to know."
The time to swing his right hand once more had come.
No. Even if his right hand had held no special power, what Kamijou Touma did would likely not have changed. He would have stood up to that crisis developing before his eyes and opposed the giant power lurking in its center. What he had been doing up until then was removing the weakness that divided his path based on whether he already had power or not.
And...
If it did not matter if one had a special power or not...
"Wait," said Hamazura, interrupting him.
As long as one had the will.
It may not have been at the level of Kamijou Touma, but he had overcome a few crises of his own.
Hamazura had protected the personal world around him.
But...
If the larger world spreading beyond it had not been protected, he would have lost the entirety of that personal territory.
Fremea did not know exactly what was going on, but she must have sensed the unrest in the atmosphere because her face grew cloudy. Hamazura grabbed her shoulders and pushed her away from him as he spoke.
"If the truth of World War III really is what Birdway says it is, then the world owes you one. In that case, you don't need to make that debt any bigger. I'll do my part to pay you back bit by bit."
"..."
Accelerator did not say anything, but he seemed to agree.
In actuality, it had not been Kamijou Touma's actions alone that had ended that war. It had mostly been the actions of many, many people intertwining complexly and supporting Kamijou. That support had been so great that a mere high school boy with a special power had been able to stand at a crossroads in history. And Accelerator and Hamazura Shiage had likely played a role in that supporting power.
But at the very least, a portion of that power was able to gather again at least partially due to the fact that Kamijou Touma had survived to that day.
Academy City's #1 flipped the switch on the electrode on his neck, and jumped up from the balcony to the roof.
Hamazura headed for the dorm's front door and spoke to Kamijou without turning around.
"You wait here. You've been working too much."
The sound of the door opening and closing reverberated through the dorm.
Kamijou looked back down at his right hand, and smiled slightly.
Just because he had a special power did not mean that he had to do anything special.
Just because he could negate all kinds of supernatural powers did not mean that he had to go charging out to stand as a shield before all kinds of powers.
Just as Kamijou was once more thinking deeply on the meaning of that, Birdway yawned and spoke.
"But those that will die without the necessary piece will die."
"Dammit!! I really just can't ignore this!!"
Part 2
The black stone did not even have the slightest scratch, and it was polished like a mirror.
The cylinder made of heavy stone rolled around like a drum with a mind of its own, and headed for Kanzaki at high speed.
A normal person would have likely met a fate similar to getting run over by a road roller.
"Tch. So this magic user is the type that doesn't show his face!!"
Kanzaki clicked her tongue and reached for Shichiten Shichitou, the Japanese sword longer than two meters that hung at her waist.
Technically, she was using the seven wires for a slicing attack.
Nanasen.
She aimed for the pathway the mysterious cylinder was moving along rather than the stone itself. She did not know how tough her enemy was, but Kanzaki knew that she could slice through the pathway. And they were on the lowest level of a fortress floating at an altitude of eleven thousand meters. Without that pathway, even the strongest enemy could not avoid falling.
She unhesitatingly sliced through it.
That bottom pathway extended from pillars hanging down from the giant ceiling above her head. She accurately severed only the narrow pillars on the right side of the pathway. The pathway lost its balance, and the entire floor tilted to the side.
Kanzaki was standing just far enough away to not be affected, but...
"!?"
An explosive wind blew violently.
Immediately after Kanzaki realized that it was a giant sphere jumping around the remaining pillars and charging towards her, a dull shock ran through her gut.
That's right.
A sphere, not a cylinder.
(Gh... bh...!! It can... change shape!?)
She did not even have time to hold it back with her sword's scabbard.
The sphere sank in.
Kanzaki's breathing felt like it would stop, but then the sphere made its next move.
It was changing shape again.
The enemy became a cylinder again, and opened up like a pair of double doors, revealing its insides. The action was similar to an iron maiden opening, but the inside was not filled with iron spikes.
What lay inside was a giant crossbow.
Without bringing her breathing back under control, Kanzaki immediately swung her body to the side.
It fired a projectile that was as thick as a human arm and more like a stake than an arrow. Kanzaki just barely managed to evade it, but by that time, the enemy had already closed and returned to its original cylindrical shape.
The cylinder took an action similar to kicking off one of the pillars connecting the scaffolding to the ceiling, and managed to get some distance between itself and Kanzaki. When the cylinder landed on a different piece of scaffolding, it remained in a diagonal position, balancing itself on the edge of the bottom circle.
It then spun around once.
Immediately afterwards, a change occurred in the metal balloons that were providing lift to Radiosonde Castle.
With a sound like overflowing steam, a large amount of gas started to be emitted.
It was not due to what Kanzaki had done.
The rate was much too fast.
The enemies were clearly trying to drop Radiosonde Castle on the target location.
(...So they really are after Academy City!!)
Kanzaki gritted her teeth, and the cylinder opened like double doors again.
The contents were exposed.
This time, it was not a crossbow.
What came out were multiple matchlock guns, their barrels lined up in a row.
The hammers that had cigarette-like flames burning at the ends all fell in unison.
The sound of them firing rang out.
Immediately afterwards, Kanzaki Kaori unhesitatingly charged forward.
Kanzaki could travel faster than the speed of sound, so avoiding those bullets that were traveling at subsonic speeds was like an expert martial artist truly going in for a cross counter against a child.
Her speed and reach were greater.
The crossbow from before had caught her off guard, so her reaction had been delayed, but when she could predict that a projectile was coming, she could get the timing right every time.
Kanzaki's footsteps exploded out and seemed as if they would destroy the pathway, and she lowered her hips and moved her head in order to accurately evade the multiple lead bullets. She continued forward, accurately aiming for the enemy that had quickly returned to its cylindrical form.
(This thing opens up faster than I expected. I won't have time to draw my sword.)
Kanzaki calmly analyzed the situation.
She unhesitatingly struck the cylinder with her right leg.
Perhaps as some kind of defense, the cylinder changed shape to a perfect cube, but that did not stop the attack.
Kanzaki sent the enemy flying a few dozen meters away.
A few of the pillars supporting the pathway were destroyed, and the entire pathway tilted. Kanzaki had been intending to send it out into the empty sky, but either by coincidence or by the object's intent, it managed to stay on the pathway as if it were hanging down from the pathway's remains.
(...Dammit. The magician himself might be worth it, but I don't have time to play around with some toy!!)
Kanzaki gritted her teeth, and then felt a chill run down her back.
She was wrong.
The flow of magic power was different from a mere spiritual item.
(It isn't using what is stored within it... It is refining magic power within itself and circulating it. It couldn't be...)
The net of a cube had a few different patterns it could take, but one of them was a cross.
If that cross corresponded to the form of a person...
"Th-this isn't a spiritual item? This is the magician himself who has optimized his physical body into this form!?"
Kanzaki did not just have a massive amount of power. She also carried out delicate analysis and operations, and that was why she had noticed that something was off.
In response, the cube spread out its sides, forming a flat plane in the shape of a cross.
She heard a strange noise.
It was a laugh.
It was the kind of laugh that barely reached one's ears, one that a girl would make with her hand up to her mouth.
"Hee hee."
But it was not just a single laugh. At first, Kanzaki thought there were other magicians around as she paid close attention to the source of the sound... but she finally frowned in confusion.
It was coming from that cross-shaped plane.
Countless sets of human lips both large and small appeared on its surface.
Because the plane was made of smoothly polished cold inorganic stone, the bewitching lips that were covering the surface seemed horribly out of place.
"Hee hee."
"Hee hee."
"Hee hee."
"If you correspond the cross shape with the human body, it would be theoretically possible... but would anyone really go that far!?"
"Wrong," sang all the lips in unison in a delicate soprano that was at complete odds with the form the voices were coming from. "Mjölnir from Norse mythology also corresponds to the cross, but Thor who possesses Mjölnir is not just a thunder god. He is also a god of agriculture who controls all forms of weather, and the hammer is also used as a symbol of granting children."
That was right.
The enemy's form was not fixed. The cylinder, the sphere, the cube. Only the cube could correspond to the cross, but there was something else that all the forms could correspond to:
A hammer.
And the crossbow and matchlock guns must have also given it the properties of a projectile.
Just after Kanzaki realized that, the countless lips that had appeared on the surface in order to chant began reciting a spell in unison.
A storm of bluish-white lightning began to appear in every direction from the cross-shaped plane from which the enemy had taken the form of a hammer.
Part 3
Accelerator flipped his electrode's switch, temporarily releasing the power of the #1, and jumped up to the roof of the tall building in one leap.
He stood on the railing, and looked around.
During the war in Russia, he had come into contact with "something like magic", and he had used a part of it. His body had been torn up from the inside by that power, but he had managed to save a girl from the brink of death in exchange.
He had taught himself to contact that power.
After receiving some explanations from Birdway, he had been able to give clear outlines to that vague idea he had before.
He breathed in, stopped, and then used his power.
"...!!"
The blood vessels around his temples pulsated unnaturally. The cold wind was blowing on him, but he could not stop an unpleasant sweat from coming from his body. He envisioned a cup so filled with water that it was just barely able to hold it all in via surface tension. If it was tilted even slightly in any direction, something that must not be spilled would spill out. He understood that clearly.
He could not ignore it.
He controlled the power within his body with the delicateness of someone balancing that cup on top of their upraised index finger. He then continued his work.
Yes, his work.
He discerned the paths of the power flowing within the city or flowing in from outside the city and then flowing back outside the city.
However, he was not directly seeing it like beams of light. Just like seeing the flow of the colorless wind in a swaying meadow, he indirectly detected it by detecting the movements of things affected by the power rather than the power itself.
In other words, he watched the flow of people.
(That Birdway brat said that feng shui causes the energy of leylines to bend depending on the locations of mountains and rivers and that the most suitable palaces are built in the most suitable places for that reason. I don't know if these rules apply to the entire world, but it seems this world is divided into comfortable places and uncomfortable places by the flow of energy through the planet.)
Of course, if you removed the occult from the equation and thought about it similarly to the price of land changing depending on how much sun exposure a place had, then the conditions to make somewhere "comfortable" had to actually be quite strict.
Accelerator could not determine whether feng shui was purely occult or if it was nothing more than statistically calculating what environments allowed people to live longer.
In any case, he knew that the enemy was using feng shui.
(And people will naturally flow to those comfortable places, just like how the grass in a meadow sways in the wind. I can't just detect the flow of magic power, but I can observe the movements of people from a tall location.)
When he surveyed the area from the rooftop, he realized that the flow of people was not determined simply by the abundance of shops or the transportation facilities.
There were similar convenience stores on the same road, but people clearly went into some more than others.
One could get to the same destination by train or bus, but people tended to use the same method to an unnatural extent.
Even if Academy City was the center of the science side, it was of course still a part of the Earth. Even if the city itself thoroughly eliminated all artificial magic, it could not deny the properties and energy held by the planet itself.
When he thought about it, it was obvious.
That truth made Accelerator's breath catch in his throat.
(...So there's a net formed by this non-compelling "comfortableness"? Hell, and this is right in the middle of the science side's headquarters. It's like the entire city is being controlled by some strange power.)
That power could be used artificially to create the people-clearing fields used by magicians, but Accelerator had not stepped deeply enough into the world of magic to realize that.
For now, he merely reached out his hand for the objective in front of him.
(I can understand people gathering at brand-name shops or a bus terminal building, but there are some strange movements. People are taking meaningless detours. If 'they' used feng shui to add in some trick to the ley line, then this may be a trace of that trick.)
A single spot had an unnatural amount of that kind of power gathered in it.
That power was supposed to lay out a net that created the different flows of people, but it was all gathering unnaturally in that spot like bathwater being swallowed up by the drain.
It was not directly sending people in a certain direction, but it was having a definite effect in slightly altering the direction taken by the people who were freely moving around in various directions.
(That's the place.)
Once Accelerator had his answer, he pulled out his cell phone.
He said only what was necessary.
"I've found somewhere that feels out of place. It's District 7's Central Hub Transformer Station. Some kind of twisted and stagnated power is gathered there."
Part 4
Within a radius of four hundred meters around the cross-shaped expanded cube, a high-voltage current emitted into the world exploded out all at once as a sphere-shaped storm.
"!!"
At that time, Kanzaki rushed toward the stairs leading up to a higher level. In order to get as far away from the square entrance as she could, she practically rolled across the stone floor.
Her rapid movements suddenly stopped.
Kanzaki jumped up more from something else's interference than from her own wishes.
(The electrical current is forcibly coming from the stone...!?)
"Gah..gh...!!"
Kanzaki intentionally regulated her breathing that had been thrown out of order.
That magician had modified his or her body for the sake of his or her goal. That was the result of a magic user that continued to grow in the absolute opposite direction from someone like Kanzaki who was born with bodily characteristics similar to the Son of God and could draw out a portion of his power. As if in exchange for what that magician had lost and cast aside, the power of his attacks had increased.
The very fact that he could keep up with one of the world's fewer than twenty Saints in a battle was strange.
(But this method is not in any of Necessarius's records... Is this a new type that has appeared after the war...?)
A sound like oil being poured onto a frying pan reached Kanzaki's ears.
The sound was coming from the square opening leading down.
The magician was making preparations for the second wave.
(The attack itself mostly relies on the laws of physics. It is simpler than a curse with no form, but his aim may be to weaken my legs by continuing to hit me with it...)
She heard the explosive sound of a high voltage current.
In the next instant, Kanzaki drew Shichiten Shichitou and stabbed the tip forcefully into the stone floor as if she had timed it.
She cut into the stone like it was made of tofu and then felt a different type of resistance.
In other words, she felt herself slicing through the high voltage current and neutralizing it.
(There are legends of swords slicing through lightning in Japan. In a country with such harsh changes in the weather, you cannot name yourself a magician if you do not have an understanding of how to deal with a thunder god!!)
That was what magic was.
It exceeded the laws of physics and brought one to an absurd battlefield.
If she messed up the timing of her attack, she would receive the attack head on, so she could not let her guard down, but she could deal with spells of that level.
Just as Kanzaki had determined that, she felt an unpleasant feeling at the nape of her neck.
It was not a physical sensation.
It was commonly referred to as a bad feeling about the situation. However, when there was a concrete basis for the feeling, it could not simply be laughed off.
In other words...
"What...? What is this massive amount of magic power...!?"
In order to observe the enemy, Kanzaki headed for the square entrance.
She stuck only her head out and saw the expanded cube that was her enemy. The magician's physical body was modeled off of Thor's hammer Mjölnir and resembled a cross. It was not standing upright or lying flat on the pathway. Instead, it was flying calmly in the air like a kite.
There was regularity to its movements.
It was moving in a giant circle that had a radius of twenty kilometers. Bluish-white sparks flew along seeming to trail it. Like that, the Throwing Hammer drew a clean circle. Its speed increased. It was not fixed in place. It rapidly moved up like the curve of a quadratic function. In just the ten seconds Kanzaki had been watching, the enemy's actual form had disappeared from view, leaving only the giant bluish-white glowing circle visible.
It was much too ominous a phenomenon to be referred to as an angel's halo.
From the flow of magic power, the circular symbol, and the Thor's hammer form the magician existed in, Kanzaki was able to guess what was coming next.
She unhesitatingly fled.
A bluish-white beam of light appeared coming from below and heading up as if to stab into the heavens. It shot straight through the center of that twenty-kilometer-radius circle.
Immediately afterwards, a third of Radiosonde Castle was utterly annihilated.
