Akuyaku Fureijou-sama to Oyobi!

Synopsis

Nao Ookami, a devoted fujoshi deeply passionate about BL, met a tragic fate in a sudden traffic accident—or so it appeared. To her astonishment, she finds 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... a reborn Nao Ookami discovers something even more urgent: this world lacks any notion of Boys' Love... (Kadokawa, translated)
