We also mustnt forget about Satoruīs ability itself. How did it come to be, what exactly is it? Is this a 1 cour-series? If so, I expect that mystery to be solved as part of the ongoing childhood-story. In that case, there might be more to Kayo and those murdered girls than face value. Iīm especially suspicious because of that talk between the teacher and Satoruīs smart friend. Wouldnīt put it past possibilites that he, too, has the same ability as Satoru and tries to interfere with the past. Would certainly be exciting.
Btw. why was Kayo so shocked when Satoru said "Thatīs because I chose not to lie to you"? Without the contect of knowing about Satoruīs real age, whatīs so shocking about it? Itīs cute, if anything.
