Here are some that don't have romance, it's been a while since I've read some of them so I apologise if I'm incorrect-

- Yakuza Reincarnation
- A Stepmother's Märchen (Goes back in time, has romance but not the focus of the story)
- Higeki no Genkyou tonaru Saikyou Gedou Rasubosu Joou wa Tami no Tame ni Tsukushimasu
- Sengoku Komachi Kurou Tan!
- The Reincarnated Great Saint Hides Herself as a Saint
- Villainess Level 99 ~I may be the Hidden Boss but I'm not the Demon Lord~ (In the novel there's an ML but he doesn't appear much)
are there any isekai mangas or manhwas with a female protag that doesn't focus on romance? any recommendations are appreciated!
