if you look for shonen isekai im sure you’ll find some but from what i have observed the “villainess” trope is mostly for female mc stories and usually the ones with male mc are underdog stories. i definitely have read some villain stories but i cant think of any names rn tho…
heres a few others off the top of my head

Like are there any stories that have villainess plots but the villianess is a male? Like I'm kinda craving a baddie male lead rather than a predictable fl story.(〜￣△￣)〜
