最強の魔物になる道を辿る俺、異世界中でざまぁを執行する

Description / Comments

Protag’s father adopts a girl after her family dies, and the protag tries her best to be the very best oneesan possible to her. However the adopted girl is a massive conniving bitch who lies to/manipulates everybody possible to hate the protag and basically make her life miserable, because reasons. However in the depths of despair she comes across a small black dragon who for some reason helps her out, and it turns out it’s because he’s a japanese dude who killed himself by jumping in front of a train. The perspective then swaps from the girl protag to the isekai’d dragon while the dragon helps get back at the conniving bitch.

I never thought i’d come across an edgy isekai manga that makes kaiyari man’s writing seem good but here we are.
