You know, everyone is saying it is predictable...
AND IT IS, not denying that...
But out of all "guy gets a harem" this one specifically is one of the most justifiable I've ever seen.
Oh, his power level is ridiculous, but he
did just save an assassin thatthought she was going to die three times in succession. First by defeating
the incarnation of death, then by saving her from her evil power up, and then from using the weapon he just got to defeat one of the most powerful monsters around.
Surely beats the old "buy this slave but does not treat her like shit", "be a nice guy that doesn't talk much before both him and the girls are isekai'd" or "talks casually with rich girl who everyone treats hiper-respectfully"
hey man, if some guy just starts killing literal death and a bull while ripping some unwanted curse out of my heart i'd be falling too.
no homo tho.
Basically this, you posted while I was typing.
