@FrostySeven i know this is an old comment, but did you really expect a high school student to experience a 180° personality change into a fearless fighter immediately after he realizes that he's immortal? he spent his whole life aware of his mortality; not to mention he still experiences pain at the same intensity level. that mentality of avoiding pain/death isn't going to change in a day. maybe in a shounen manga with a gary stu protag, but this isn't that. if that's what you're into, i would say, yeah, this isn't the series for you.
though later in the manga,
as he experiences death more, there are moments where he doesn't hesitate to commit suicide to reset himself or intentionally leave himself vulnerable to injury (knowing that he can reset himself later on)
2. Why is there no other chapters? Because there's official translation. So there's no point of scanlating.
Oh you bet there are, you just have to keep searching 😏
@Alvataire - those 'other chapters' have not been scanlated by any group they are pirated content of official/published chapters - hence why MD does not have those chapters. .
