Raze is a girl who was reborn in another world with her memories from modern Japan intact. Relying on her past life's memories, she rapidly rose through the ranks as a soldier. At the age of 15, she is an elite military officer in the Cyan Empire, where she is known as "Wolf Fang." Her boss, the devilish Prime Minister, orders her to go undercover at the "Central Imperial Magic Academy" as a student to watch over the children of the sons and daughters of the empire's rich and powerful⁉ At the school, Raze becomes friends with Folia, a user of healing magic, and the Countess Kana, while enjoying the peaceful school life that is completely different from her life in the military. Until one day when Kana suddenly told her, "This is the world of an otome game, and I'm the villainess." In order to avoid the Bad Ending, Raze will have to use all of her military skills and magic powers to take down the death flags one after another. But she is overwhelmed with unexpected developments! (Source: Ichijinsha, translated)
