Man, just re zero all over again. And also, it was 4 deaths, not 3. And didn't Subaru's first mission (that's what I'm gonna call it but it was more like prevent Emilia from dying) also take 4 deaths? XD Nice, i guess I'll continue...
Return by Death on Steroids. Subaru from Re:Zero would wish to get buffs from his deaths, but instead he has to stay a weak human. I wonder if the skeleton's ability of this story will have a limit in some kind of form. if not, he will quit quickly become OP.
