My System: An Evolved Computer I Made With My Unique Ability—

In the meantime, Tatsuki and Ayumu approved of Aira staying at their house. Of course, they made sure to ask Emma if she'd be willing to share her room with Aira since there was only one guest room available. It would only be a temporary stay though since Tatsuki volunteered to clear the storage room so Aira could have a room for herself. Satoshi heaved a sigh of relief. Even though he was a bit hesitant to ask his parents for help, he knew that they'd support his decision after completely hearing him out. And he was right on the money, they really did agree even though they haven't heard the entire story.

For a moment though, they thought that Aira was actually Satoshi's secret love child. That's why there was a heavy atmosphere during the entire trip from the police station. And that heavy atmosphere got even heavier as they nervously waited for Satoshi's return.

"Thank you," Aira mumbled before Emma  led her to take a shower. Before she entered the shower with Emma, she waveringly turned around and bowed toward Satoshi's parents. She wasn't just saying her due thanks to them, she really meant it when she said it. She was grateful that they were willing to help her even though they didn't initially know her identity.

Back then, when she decided to cast off her dad to the police, she actually had no idea how she'll be able to survive. After all, even though her father treated her poorly, he still fed and clothed her. Without him, Aira couldn't live in the big world out there. Still, she went through with it in hopes that Booster Incident would come to a close as soon as possible. She knew the story from her father, and even though she was on the wrong side, she was perfectly aware of who was in the right and who was in the wrong. That's why she didn't think twice about her decision. When she saw her chance, she took it, no question.

"So... you can go back to the past, huh, that's actually pretty cool. So you already know what my superpower is?

" Emma was still skeptical about her superpower so she decided to test her.

To her surprise, Aira shook her head. "You've decided not to tell me your superpower as a test, so Aira doesn't really know." She continued.

"Oh, so I never said my superpower to you in the future? How far can you go back to the past?"

"Half a day," Aira promptly answered. "The sun is going down, right? Aira can go back to the past when the sun is still going up."

"Okay then, I'm going to tell you my superpower after we're done taking a bath. Do you know my superpower now?" Emma said with a smile, patting Aira on the head. Now that she knows what her superpower is and its limitations, Emma found a loophole that helped her test Aira. Her superpower may be powerful, but just like any other superpower, it isn't all that invincible as well. Just look what happened to someone with almost the same superpower as Aira, the Chronicle. He was killed and he couldn't even avoid it.

"You create portals, and you can go wherever you want. Aira wants to go to the Eiffel Tower!" Aira's eyes sparkled with delight as she jumped up and down with glee. She closed her eyes, emphasizing her pudgy cheeks as she acted cute in front of Emma.

"Sure sure, let's go there with Satoshi next time." Emma genuinely offered. "For starters, why don't we hop in the tub?"

.....

Satoshi sat in his room, the solitude granting him the tranquility he much deserved.  Recently, with the help of some important people in his life, his superpower underwent drastic changes. Fortunately, he was able to keep it under control, but for how long? And what could he do to better rein his superpower in? Those questions invaded Satoshi's mind, robbing him of the peace he much enjoyed.

This is where it all started, right in this very room, after he played his favorite game of Laser Fingers. He turned his head towards his empty desk where his retro computer once stayed. Dex, that computer now had a name, and he was the most solid sign that Satoshi had already awakened his superpower.

A lot has happened since then, invasions, minor incidents, school competitions, and tournaments. So much had transpired that Satoshi felt like he was inside a very long dream. He was already living the life he hoped for back then. Despite the fact that it brought an equal amount of hardships, it was still worth it, or at least that's how Satoshi felt.

"Dex?"

[Yes, owner?]

"Can you show me Nailgun's stats?" Satoshi held his breath. He knew that all his familiars underwent changes. At most, Satoshi assumed that all of them climbed a rank or two.

Satoshi's familiars were recorded by Dex, down to their minute details. That's how Satoshi could keep a record of them. All this time, he only looked at Nailgun's information, and rightfully so since Nailgun is his first familiar. Also, it totally flew over his mind to check his familiars' grades and abilities. His superpower is too flexible after all, and to be honest, he felt really powerful every time he uses it. That's why he didn't sweat out the small details.

Right now, however, things took a turn and he had to take a step back and try to look at the whole picture before anything else. His familiars had gotten so powerful that he might come to a point where he couldn't control them anymore and that could even injure someone badly, or worse...

Satoshi dreaded the thought. At the same time, Dex pulled up Nailgun's grade and abilities, showing itright in front of Satoshi's face.

[Nailgun: S-Grade

"What?!" Satoshi exclaimed in disbelief, bolting upright from his bed and alarming everyone in the house.
