To Kyoka's and the demons' surprise, Alex can actually break the Sensory Deprivation Curse. Even the Pain Amplification Curse is destroyed.
It's actually thanks to the Tailed Beasts who have analyzed the Curse while Alex is fighting the demons.
They found out that Kyoka's Pain Amplification and Sensory Deprivation Curses were a type of very powerful Genjutsu.
They mess with the targets' minds because the feelings of pain and sense all need to be felt by the mind.
The sensation signals from the nerves are sent to the brain.
By increasing the brain's sensitivity to pain sensations from nerves, everything can become painful.
Then by blocking all signals from the physical senses, the brain can't process any of the 5 senses, so the targets can't see, hear, smell, taste, or feel the touch.
That's also why the Curse can't affect 6th sense because it doesn't come from nerves' signals. It is the feelings from hearts that come from experience.
Manipulating the brain functions to perceive things is the basic concept of Genjutsu. Normal genjutsu makes the brain hallucinate through the targets' senses like sight or smell.
Kyoka's Curse also manipulates the brain functions in a different way, but the concept is the same. That's why the Tailed Beasts just need to tweak the method to release Genjutsu a little to break Kyoka's Curses.
Alex could break them earlier, but he could feel his non-physical senses were getting sharper, like his instincts and his magical senses. They were being polished when his 5 senses were blocked.
He is obsessed with training all parts of himself, so when he finds a chance to do what he normally can't, he immediately takes the chance even if the situations aren't ideal.
But he knows he needs to finish the fight soon, so he stops playing around and breaks the Curses. Now all his senses return to normal and every move doesn't hurt anymore.
"Well then, I'll show you the true might of Magic. This is a new spell we've developed, so please give us your feedback."
Alex raises his hands to the front with his palms facing each other. Tiny dark red and transparent blue energy balls appear and merge, forming a dark purple ball the size of a volleyball.
"Tailed Beast Fireworks!"
Numerous bright red bullets shoot out of the Tailed Beast Bomb from all sides. It looks very similar to Sting's Holy Ray because it is inspired by that.
Kurama can shoot Tailed Beast Bomb rapidly, but only one at a time. This spell can shoot many bullets at a time. The power of each bullet is weaker, but they can cover a wide area and they are faster.
The Tailed Beast bullet rain looks like fireworks when they shoot and explode, hence the name. They hit the demons from all sides with very high speed and powerful explosions upon contact.
While they are weaker than the usual mini Tailed Beast Bombs, they are still very strong. Even Hades's Bullet Magic is nothing compared to these Tailed Beast Bullets.
The demons try to dodge and block the bullets, but there are too many and they are very fast. They even come from behind as if circling around the demons to make sure every side is hit.
Their defense skills are destroyed after a while too because they can't maintain them too long. If they want to compete in endurance, then Alex will welcome them every time. He can fight for days nonstop, so these demons won't stand a chance.
He overwhelms them with his nonstop attacks until they can't defend themselves anymore. No matter what defense or counter attacks they use, Alex's Tailed Beast Bullets destroy all of them with sheer numbers and power.
After a while, Alex finally stops. The room looks messy with sand scattered everywhere, craters on the sand, and injured demons. But the room itself is intact because Alex made sure that the Shukaku's seal he used was the strongest.
So there's no real damage to the room, only scattered sand and gravely injured demons buried by sand. Alex grins and transforms into a mini Shukaku again to bind the demons that are still alive.
He binds them with sand and wraps them with Shukaku's seals to make sure they can't move, only leaving their faces open. But their mouths are covered because they might be able to use Curse with their mouths.
After the demons are sealed, Alex removes the room's seal, making the ceiling and walls that have been turned into sand crumble.
Then he crushes the emergency call lacrima crystal in his pocket and leaves. It's not to tell his friends that he is in danger. It's just to make them come here later.
But his emergency call obviously surprises everyone. After all, it's Alex. He is the last person they wish to use the emergency call. After all, if he needs help, then he must be fighting an enemy stronger than him while he is the strongest among them.
Fortunately, when Alex gave them the emergency call lacrima crystals, he told them that he might use the crystal for something important, not just when he is in danger and in need of help.
So now they are hoping that Alex only calls them for something important, not because he fights an enemy he can't defeat.
He told them that if he uses just 1, then it's just an important matter and they don't need to rush to his place. If he uses 2, then it is an emergency situation and he needs their help ASAP.
They wait and there's no other signal from Alex, so he only calls them for something important, not truly an emergency, so they don't need to rush now.
Some of them are still fighting many small-fry demons and demonized humans. These enemies are not too strong individually, but their numbers are just too high. They even wonder where Tartaros found these demons.
There are also some strong ones among these demons, but not at the level of the Demon Gates. Still, they are pretty strong, on par with most of the Grand Magic Games' players and A-Class Mages from most Magic Guilds.
These demons lead the weaker ones too, making the fights even more difficult. The demons' different abilities also increase the difficulties.
But most of the Mages can overwhelm the demons with pure power, like Ultear, Laxus, Mira, Erza, Natsu, or Gajeel. Some like Lucy have good strategies while some like Sting, Rogue, Wendy, Lily, Elfman, or Lisanna have a lot of perseverance.
Gray has an even better advantage because his Ice Devil Slayer Magic is very effective against the demons and half-demons. He also can use them to get used to his Ice Devil Slayer Magic.
They focus on defeating their enemies first before going to where Alex sent the emergency signal and the earliest to finish are Mira and Elfman because most of their enemies are resurrected corpses.
The resurrected corpses suddenly stop moving when Keyes gets defeated. They don't disappear because Keyes is still alive, but they can't move because the command from their necromancer has gone.
It makes defeating them very easy, so Mira and Elfman finish quickly and go to where Alex's signal came from. There, they are surprised to see the 8 Demon Gates wrapped in sealed sand while Alex is nowhere to be found.
Then they find something written on the sand floor.
"For Mira and Gray? What does that mean?" Elfman tilts his head in confusion.
Mira looks at the message and then at the demons. She quickly understands Alex's message and smiles.
"He wanted me to Take Over some of these demons and leave the rest for Gray to kill. I will get the demons' abilities while Gray's Ice Devil Slayer Magic will get stronger by killing them."
Elfman finally understands after his sister explains it.
"But what if you want to Take Over all of them?" He seems a bit greedy now.
"I don't think that's a good idea. Controlling them will be very difficult. Do you want me to lose control like you when you had just Took Over that King of Beast?"
Elfman is reminded of when he couldn't control the King of Beast in the beginning and always got his ass whooped by Alex until he could control it.
His rampage was already bad back then. If it's his sister who's much stronger than him who goes on rampage, then even the Capital could get destroyed.
Mira then tries to sense each demon's power by touching their faces that don't get covered. She can feel the compatibility between her and the demons as a Take Over Mage.
The most compatible is Seilah, then Kyoka. They are female demons, so their compatibility with her is high. But one of the male demons actually also has a pretty good compatibility with her, it's Jackal.
The others aren't so compatible with her, so she decides to Take Over these 3. She is quite worried about Taking Over a male demon like Jackal, but their compatibility is quite good, so she doesn't want to miss this chance.
She can just not use his power if it becomes a problem later, so she decides to use Take Over on Jackal now. The others will be left for Gray to kill.
Elfman sighs because he can't Take Over demons or he will use it on at least one of these guys. He knows that they are strong or Alex won't leave them for Mira to Take Over.
Now they just need to wait for the others to come here. Meanwhile, Alex is finally facing the final boss. He has met Mard Geer Tartaros, the King of Underworld.
