Like how the mc is an assassin and not the hero and he gets kicked out of the human kingdom cause the royals are corrupted.
MC is obsessed with the whole stay in the shadows/keep your identity a secret stuff. He is OP but acts like he isn't. MC says a whole bunch of nonsense but somehow they become the truth and through that he got suburbanites. The lackeys think he is telling the truth and take everything serious but MC hasn't realize he started something HUGE.
-Mc was kicked out of hero party in secret the actual hero didn't know about this.
-Hero is MCs little sister, hero and mc have good relationship.
-Mc wants to live a quiet normal life now
-Mc is Forced to act like the game character.
-Mc is kind hearted but has to act rude.
-Mc is pretty powerful and he is trying to save his house from ruin I believe.
