This is a tale that distorts the scenario of an otome game. An orphan girl named Alicia is attacked by a woman trying to steal her body to become the “heroine”. From the fragmentary knowledge she acquires, Alicia learns that this world is the stage of an “otome game” in a “world of sword and magic”. Having learned the truth from the knowledge she obtained, the immature Alicia dismisses the otome game as “nonsense” and runs away from the orphanage to escape the fate of the “heroine”. A villainess aims to take her life. A fake heroine appears. Alicia trains herself using the fragmentary knowledge she has gained in order to survive, growing into the “Strongest Assassin” that is feared by both the Thieves’ Guild and the Assassins’ Guild.
