A theory, but hear me out: In order to unlock the hidden character, you have to play all the other routes first, right? And currently, she's on all three routes and that could somewhat count as fulfilling that condition. Since the condition is filled, Akira finally started to regain his memory as a result. As for what this results in, hehehehe... Ando-sensei is also suspicious as hell. So, there could also be 2 hidden character.
Akira could also be the serial killer. Either he does it deliberate or heās having a split personaliy or suffers memory loss after every time. Itās pretty sure the serial killer has something to do with the hidden route. This means the ātargetā protects her or is the killer. It would fit to Akira to do this out of fun.
