Back then, Satoshi dreamed about the same dream his grandfather did, about how he was graciously chosen to be a Disciple in the near future. And for a couple of months, Satoshi would feel even more motivated about awakening his superpower no matter what it was.
He would try everything, even reaching the point where he fervently prayed every day in hopes that he would awaken a superpower. It didn't matter whether the superpower was subpar or not. All he wanted was to get one.
When Satoshi came to, it had already been a couple of hours since he collapsed right in front of the three girls. Although falling into consciousness was somewhat understandable after everything he did, Satoshi thought otherwise and he felt embarrassed when Elimine and the Nurse saw it.
