Promised Tomorrow (Part I).Yuta takes Mana to visit the grave of the Kogure family grave where 60 years earlier, he knew a kind girl named Nae. Mana then encounters a girl being chases by a man with dogs and intervenes to save her. The girl kills the man with a rock, but Mana is blamed and his associates kill and bury her. Yuta searches for Mana and encounters Sokichi, an old man who was Nae's servant as a boy who says that everyone believed that Nae had left with Yuta, abandoning her fiancee Eijiro. Meanwhile, Mana revives and discovers that Eijiro has kept Nae confined on his estate, looking perpetually young, but without any knowledge of her past. Meanwhile, Yuta is captured by Eijiro's men and knocked unconscious and he calls how Nae told him how a travelling nun left mermaid ashes which Nae used to create the Red Valley, a field of perennially blooming red flowers. When Yuta awakes, Eijiro tells him that he found Nae's body in the Red Valley, and Yuta tells him another version of the story of mermaid ashes in which a villager killed a nun to steal the ashes, but the nun came back to life and killed many of the villagers. Nae kills some of Eijiro's men and leaves with Mana following her. Eijiro orders his men to recapture Nae unharmed but to decapitate Yuta and Mana.
