When Miyu takes on a shinma known as Ryu, Larva lets him get away, much to Miyu's suspicion. Ryu, reverted to human form, is taken into the hospitality of another shinma named Nami, who serves as a prostitute in her human form. Ryu tells her that he has inherited a death crystal in his heart, which forces him to fight against his own will. Larva senses the "light of the sea", and he sets off on his own to look for this in his hometown. When Reiha and Matsukaze locate Ryu, Nami steps in and creates a barrier to disallow Miyu from hurting both of them. However, Nami becomes weakened and the barrier disappears, and it is soon realized that Nami has also been infected with the death crystal. Meanwhile, Larva easily defeats Barrow, becomes overwhelmed to unconsciousness by Lilith and is taken on the ghost ship to Garline, all of whom are Western shinmas acquainted with him.
