What Brave: Gunjyou Senki is

Honnoji Academy. Clattering arrows. A loner sharpens his game while a friend pleads with him to lighten up. Then lightning, anachronisms: a campus overrun with katana-wielding samurai. They've been flung into the past, right into the meat grinder of the Sengoku era. It's *Azumi* meets your old high school, if that sounds like a thing you'd watch.
