While out walking, he comes across the Kyogoku Tavern where he has an encounter with Kyogoku Tei and the Hermits who point Momosuke to Shikoku to help the Ongyou who "vanished" while on an assignment. Momosuke comes across some fishermen who had lost some of their own to these sea ghosts. The fisherman tell Momosuke that the sea ghosts have been appearing near Kabuto Island instead of Twin Island as one of the fisherman tells him that one of the islands that make up Twin Island just vanished. The fishing magistrate Lord Sekiyama appears claiming that the sinking of boats is the work of the Kawakubo Clan and that he has taken action to remove this threat. While trying to get info on them, Momosuke is ambushed by some strange warriors only to be saved by Ogin. Ogin tells Momosuke to turn back and head home. After Ogin leaves, a man approaches Momosuke who tells him that Ogin took a boat out to sea bound for Twin Island...
