Toki Misao

Hardcore fujoshi is reincarnated as the rival character from an otome game she begrudgingly played. She's supposed to bully the heroine, but chooses instead to teach her the wonders of BL, hoping to spread it to many others throughout the world. However, an outrageous interloper makes their entrance... her very own fiancé. \[From Baka-Updates Manga]

Nao Ōgami, a devoted fujoshi deeply passionate about BL, met a tragic fate in a sudden traffic accident—or so it appeared. To her astonishment, she found herself reincarnated as Clathiras Levanta, the antagonist character in the game Asteria Academy Chronicles! In the game, Clathilas embodies the archetypal villainess: she mercilessly torments the heroine and ultimately meets her own demise—a predetermined fate. However, instead of being overwhelmed by such a sorrowful outcome… the reborn Nao Ōgami discovers something even more urgent: This world lacks any notion of Boys’ Love?!
