u might have seen this already but Youjo Senki/The Saga of Tanya the Evil is the best example of this trope
Vouching for this recc
Rimuru
I've seen the anime that covers a portion of the story. Will add that to my list! Thanks! Just saw an announcement that "The Old Man Reincarnated as a Villainess" is getting an anime adaption next year and it just piqued my interest. Haha
Ahh! Absolutely love the anime! Didn't want to spoil the anime for myself so I avoided reading it. But I do know the anime does gloss over some good bits. lol May read if I get too impatient.

just remembered this story has this trope too:

I will only say this. Manga is bit different from anime, and novel (which is the original) also different from anime and manga. They have same plot. But little bit different
Any isekai where main character is reincarnated as the opposite gender? BL, GL, straight, no romance, anything is fine. Preferably completed. If not, that's okay too! (๑⌒ᴗ⌒)و✧
