Most of those questions get answered much later.
Only thing I can say is Mahito was the only one who could heal mechamaru. There’s very few RCT users in this universe and they all are either unhelpful, can only use it on themselves or don’t have the understanding to heal him
Yea I was bouta say
@Hades he's doing a different thing
Mahito reshapes the soul, it's not the same thing as RC, technically he just mutated him the same way he does everything else, but just left him in human form
the S1 arc with Junpei is the most explanation you getting
No idea what's up with Yuki tho, I agree
she the type to gaslight an incel into doing a serial shooting, reckless as hell
