Gunjou Senki

High-school student Nishino Aoi is a history enthusiast and a skilled member of his school’s archery club. He sometimes imagines he would have been better suited to Japan’s Sengoku period, where he might even have married his clubmate Seno. In the present, however, Seno is his friend and the girlfriend of his childhood friend, Kouta. A mysterious fog envelops the school and transports everyone there to the Sengoku era, near Azuchi Castle, sometime between 1576 and 1582 by Aoi’s estimate. The students and teachers soon face a brutal attack by armed men accompanying the historical figure Hachisuka Koroku. Aoi and his friends must try to survive in this deadly time.
