Catarina Claes, the young daughter of a noble family, one day bumps her head and regains memories of her past life as an otaku. It is then that she realizes she has been reborn into the world of the otome game Fortune Lover, reincarnated as the game's villainess who, regardless of what route the player took in the original game, is doomed to be either exiled or killed. In order to avoid these routes that lead to doom, Catarina begins taking countermeasures. This, however, ends up having unexpected consequences on her relations with the other characters of the game's world.

It has been 800 years since the battle gods "Idaten", who boast overwhelming speed and strength, contained the "demons" who led the world to ruin after a fierce battle.

Bring armed forces, wisdom, politics, conspiracy, whatever you can use! No-rule & no-limit three-way battle royale is about to begin!!! (Source: MAL News)

This is a tragic eulogy to all the "boys and girls" who are now adults! (Source: MU, edited)
