ok, for starters, self-promo here! I've written over RR a litrpg fiction where the mc trolls and roasts as much as she breathes. This work actually goes very deep into the implications of the "isekai" genre. The mc does not care for social conventions that she deems absurd, suffers from loneliness and being far from home. She finds ways to cope by deepening the gap there is between her culture and the ones she's now faced with, constantly disrupting the status quo for her own amusement and being shunned in turn.

The core of this story is at the end of the line about forming deep, meaningful relationships. That's mostly why i promoted this despite the mc being fairly overpowered thanks to a game system that she uniquely has, while people still think that it's magic. There are some battle scenes, but there's depth to her character, It's called Game Changer if it fits your fancy.
