Nishino Aoi is a high schooler that loves history and archery. He even thinks his skill with the bow would be suited for the warring Sengoku period (1467-1603). And now his daydreams are about to become reality.
A mysterious fog transports Aoi’s school into a different time period that he determines to be between 1576-1582 near Azuchi Castle -- right in the middle of the Sengoku period. But this dream-turned-reality is more dangerous than Aoi anticipated. Teachers and students alike are being murdered by armed men -- and Aoi’s talent as an archer may be the only chance he and his friends survive this time period.
