I'm heartbroken but I somehow don't want seiran to be resurrected, I'll choose to have this as bittersweet memory rather than having her come back. I'm sure things won't be as great as before
I don't think it is easy to reanimation a person. Mimi's mom is a powerful witch with special heal ability. Even that she need to exchange her life. If not, school will try to create as many Mimi as possible already.
Griefi- wait what NO DONT DO IT, DONT REVERSE THE EFFECTS OF HER DEATH THERE NO POINT HER DYING IN THE FIRST PLACE THEN, or at the very least I want severe consequences, don't tread the same path as many before please
