SSG: Meimon Danshikou Keppuroku

When her brother is hospitalized, Subaru Otowa makes a bold decision to ensure his future remains secure. To protect his standing, she enrolls in his place at a prestigious all-boys high school, intending to attend classes disguised as him for an entire year until he fully recovers. Concealing her true identity as a girl in such an environment promises to be a daunting challenge on its own, but her carefully laid plans are immediately tested upon arrival. On her very first day, Subaru crosses paths with several eccentric students who react with visible shock the moment she introduces herself by her brother's name. Rather than treating her like any other newcomer, they swiftly escort her to the Lion Club, an unusual organization within the academy. These young men firmly believe that they are the reincarnated members of the legendary Shinsengumi, and they insist that Subaru must join their ranks based on this shared past life. Now, Subaru finds herself caught in a precarious double bind: struggling to maintain her male disguise while navigating the intense demands of a peculiar group convinced they are bound together by history.
