Second season of Hyakka Ryoran: Samurai Girls. The series takes place in an alternate version of Japan called Great Japan (大日本国, Dai Nippon-koku), in an alternate timeline where the Tokugawa shogunate remained active and has remained semi isolated from the rest of the world after their defeat by American forces in World War II. And the Americans have bases on Okinawa and southern great Japan. The story takes place at Buou Academic School (武應学園塾, Buō Gakuen-juku), an academy located at the base of Mount Fuji where children of military families train to become samurai warriors. The academy is in the middle of a power struggle between Yukimura Sanada and Matabei Goto of the Toyotomi faction and the powerful student council that rules the school, and Muneakira Yagyu, the owner of the Yagyu Dojo, and the mysterious Jubei Yagyu are dragged in the middle of the conflict.

OVA bundled with Niθ Art Works Vol. 2, featuring a new character named Kagekatsu Uesugi.

Ryouhei Arisu is a high school student with no ambitions and just wants to escape from what he feels is a meaningless reality. One night when he is with his two friends Daikichi Karube and Chouta Segawa, they see an abnormally large firework shoot into the sky, an event which signals a permanent change in their lives. Blinded by the incredibly bright explosion, the three find themselves transported to what is known as the Borderland. The only inhabitants of this world are participants of a deadly game where specific tasks must be accomplished if they wish to survive. As the three begin playing to determine how they can get back home, Ryouhei finds himself feeling alive for the very first time in his life. [Written by MAL Rewrite]
