For me it’s the eminence in shadow, I really don’t have anything against it but it’s just the author, recently I been giving a try to few isekai so eventually I tried eminence in shadow like I am actually impressed his motive something interesting then it was ruined by having lot of girls around more like except for 3-4 regular characters everyone else were female characters, like every time author did that I feel like they don’t have confidence in their story that they are relying on fan service and the other thing that kinda ****** me off was when he is acting cold like alright he don’t really care about his relations with other people even his sister but if he want to be a loner he would have just get off with it.
