It is so edgy that shield hero looks like a child throwing a tantrum compared to this.
@Dagashi
Yes he is more reasonable but compared to the "tragedy" of shield hero but his was more tragic.
I mean any one lifetime he could choose should be enough of a reason for him to set on a path of revenge. Not to mention the blatant credit taking(powers/destiny/girl) of the similar named guy.
But it's not edgy though, O_O
The MC makes a lot of very reasonable choices in the novel, which makes the story very different compared to others of this genre
