Aira just nodded along, leaving Satoshi in a state of shock. If what Aira said was true, then she could very well be one of the most powerful awakened to ever exist. There's also the question as to why she awakened at such a young age but that's beside the point. Right now, someone who could manipulate time possibly exists, and that powerful superpower is in the hands of a four or five-year-old.
"Look here, Aira," Satoshi suddenly leaned in closer to her, grabbing her by the shoulders as he stared straight into her eyes. He didn't know how to go about what he was going to say but time was of the essence and he had to say it as effectively as possible. He couldn't afford for Aira to just brush off his warning as a mere suggestion.
