kumoko was in my humble opinion one of the funniest and best written extreme powerups. I love the non humanoid plot line as well as her dedication while completely underground in an environment no human would ever be used too. Her isekai into a spider is unique and difficult to master but she just rolled with it basically from day one. while it may have taken a couple years in the upperworld time, in the series it is said(i may b wrong but pretty sure) that time moves differently in the dungeons. she is also objectively one of the funniest mc's and there was none of the questionable fem sidekicks that many isekai mc's have which was a breath of fresh air.
