"That is..?"
"Ah, are you not unfamiliar?"
"I think it is rare to see someone with such magic."
"Well, that's true!" Lucy somehow became proud and smug.
"...." Sato.
But she wasn't someone who got ahead of herself; no, sometimes she did, but the times she messed up were more than she could be proud of, so it was easy to imagine how comical she was, right?
"So...?"
"That's right, it is a Celestial Key Magic. The magic that I have mastered."
When she said so, her expression was so gentle, and she also had a slight sadness as if she remembered the past.
"If I am not wrong, it is a magic that summons a spirit by using the key, right?"
"That's the gist of it."
In other words, Lucy was the so-called summoner.
In the future, Sato imagined that she might even summon a dragon.
'I did.' The future Lucy.
Nevertheless, he was quite curious about this magic since it seemed to suit him well, as it didn't take much of the Magic Power, and at the same time, it meant that he also had a support that could help him in the battle.
While he didn't think that he would lose in the battle, especially when everyone was more or less so simple, if he could win the battle with ease, why should he refuse, right?
Moreover, when people fight, in most cases, those who came in a group would win, right?
Still, as he was curious about her magic, she told him everything from A to Z without hiding anything.
According to his previous plan, he wanted to ask Mirajane to ask him to use the "Take Over" magic, and if possible, he wanted to get his hands on those powerful devils. That way, he could make himself powerful and also raise the status of Sato DxD, since if he were a devil, even if he were just a half, it would bring him more benefits. It would be better if the devil that he had taken over were a devil from a house that had gone extinct; that way, his status would be better, as it would lead him to gain access to information that could make the two grow stronger together.
As for the Celestial Key Spirit, it just took off his interest since summoning magic was quite nice, right?
"Do you want to learn it?" Lucy asked.
"...is that okay?"
"Why not? Come on, I will teach you!"
As Lucy said, she stood up from her place and sat by his side, pressing him closer, letting her soft, pillowy body fall upon him.
When hard met hard, they would clash, but when hard met soft, it could only fall.
"What? What's wrong?"
"..."
As Lucy stared at him innocently, Sato wondered whether this was all a ploy within her to trick him into falling for her.
"...can I get the information directly?"
"What do you mean?"
Before Lucy could even understand, Sato showed her his magic, the Archiver, which worked like a computer.
"So, can I get permission to learn about your magic?"
"Ah, um, yes!"
By then, the information about the Celestial Key Spirit was uploaded into Sato's database.
'Hmm... should I get all of the information about the magic?'
Yes, he might not be able to use all of them, but just collecting them was enough since they could be used by his future children or sold to people who wanted to learn magic.
"W-What kind of magic is this?"
"Archiver. It's a new magic."
"...so you can get all the information you want as long as you get the permission?"
"That's the gist of it."
Even if he didn't get the permission, he could get the information by beating up the people to unconsciousness, then take everything away. Still, he wouldn't say that since he had an image that he had to keep.
"Amazing..."
"It isn't so amazing since it doesn't have much power."
"No, no! Everything has its own advantages, like every spirit, since some of them, while they aren't good at fighting, are good at a certain thing, such as haircut!"
"...."
The haircut aside, he agreed that even if some things might not be good at fighting, they could gain their advantages from other things, as everyone was born to do something in life, to search for meaning.
"By the way, have you learned it?"
"Of course not." Under Lucy's curious gaze, Sato shook his head. "I just gained the knowledge, it doesn't mean that I have learned it."
"Then, I will take that responsibility!"
"Hmm?"
"I mean... I will become your teacher! You should be happy that you can be taught by me!"
"...."
While she appeared proud, Sato wondered whether this was all a ploy, but well, it was all fine, he thought.
"Okay, then, please teach me, Lucy-sensei."
"Good, good." Lucy nodded, as she felt so happy when she was called "-sensei" by him. Still, as she had become a teacher, shouldn't she get a teacher outfit, too, and also glasses that made her look strict!
"By the way, Sato-kun."
"Yes?"
"What outfit do you think I should wear to teach you?"
"....."
As she looked at him shyly, Sato blinked his eyes and asked, "Should we go to the clothing stores to check?"
"Okay!"
As expected of him!
As he was her student, it seemed like their minds seemed to be in synch.
Still, due to this, the two went out to the clothing stores, trying various clothes for her and him, and then went to other places, trying many things in the city together as they had fun.
It was like a date.
No, it was a date!
He couldn't help but be startled as he looked at Lucy, who made him enjoy his life.
'This girl is dangerous,' he thought.
He knew well that Lucy was a dangerous woman since she could steal away Natsu, the strongest magician in the world, under her skirt in the original story, making him leave his original lover, Lisanna, who he thought was dying.
Or rather, Lisanna's fate was so sad in the original story!
Fortunately, the three siblings were all together.
However, probably because Lucy noticed him thinking of another woman, she quickly woke him up.
"What's wrong?"
Under the sunset, her beautiful face basked in the orange light, as she looked at him with a gentle expression, as her hair lightly swayed in the ocean wind, but the vanilla ice cream on the corner of her lips made her silly.
"No, there is just ice cream on your lips."
"Huh? Really?!"
She got embarrassed as she thought that he was about to kiss her, and frankly, his gaze made her skip!
Yet, as she was in a panic, she couldn't clean up her lips, and because of that, Sato sighed and moved his finger to clean up her lips. "There."
"Ah, um..."
The soft touch of his finger lingered on the corner of her lips as her gaze met his, thinking something was about to bloom, only, all of a sudden, he became a beast, and she was hugged!
"Ah, no! It-It's still too early, Sato-kun! I-I am not ready yet!"
Yet, her resistance was weak, and instead of breaking away, her body and hands seemed to touch him all over, trying to feel him better, but Sato didn't have time to reply to her, since—
"Red Shower!"
As this voice fell, hails of fiery, purple fireballs rained down on Sato and Lucy, and all the places in the vicinity with the purpose of killing them!
BOOOOOM! BOOOOOM! BOOOOM! BOOOOOM!
"HAHAHAHA, DIE!"
At that moment, Bora the Prominence was able to avenge his hatred!"
"I DID IT! I DID IT! I DID IT!"
As Bora was so happy, he didn't realize that Sato and Lucy were able to escape unscathed from his magic.
"Can you wait here for a moment, Lucy?"
"Ah, um."
As Lucy nodded, Sato directly jumped and smashed Bora, who was in the sky, directly into the ocean.
BOOOOOOOOOOOOOOOOOOOOOMMMM!
As Bora was blown on the water, he sank.
Splash!
"...." Lucy.
What the heck did this guy plan to do again?
