>3rd scenario route
>Takumi let's Eito kill Sirei because he regains his memories from 2nd scenario
>He has to choose between telling the others what happened to Sirei only for them to think that he's full of shit and just killed him for the lulz while lying about his memories
>Or he can choose to cover it up with Eito and try to find a way to fix the incoming mess of issues that will rise from his actions
This will be the TRUE Eitaku route one way or another
