Chihiro ni Sakuhana

The Saburo Fuzo of the city under the storm—the era of the Genpei family struggling for three kinds of sacred treasures. One of the three kinds of sacred treasures, the emperor's testimony, Tojin, (Antoku) a young emperor who sank underneath the waves of the sea while fighting. The deeply related swords aimed at by the Genpei family led the young emperor in the castle at the bottom of the sea where Ryujin (dragon god) and Watatsumi (sea god) live! The encounter with the bottom of the ocean, Ryujin's Watatsu Sea and his sister, Nadeshiko changes the fate of the young emperor! Fantastic retelling of what happened to the boy emperor,Antoku.
