Yuujin Character wa Taihen desu ka?

Synopsis

At school, Hinomori Ryuuga seems less like an ordinary student than a hero hiding in plain sight. He vanishes from class, returns injured, and attracts the attention of three remarkable girls: idol-like Shiori Yukimiya, swordswoman Rei Aogasaki, and enigmatic transfer student Elmira McCartney. Kobayashi Ichirou takes on the exhausting task of acting as Ryuuga's supportive best friend while trying to understand his secrets.
