Genuinely my favourite series! I cannot express how good it is. The LN has interjections from other reincarnations that some may find boring, if that's a turn-off, try the manga! It's extremely cute, has EXTREMELY interesting worldbuilding, and I just don't know how to put into words just how much I love this series.
might I recommend "so I'm a spider, so what?", the isekai manga about a loser fail girl who is isekai'd as a fucking spider.
featuring all of the tropes you know and love from isekai starring a man, but without any of the incel nonsense?
she knows she's a raging chuunibyou. and she's loving every second of it.
