In estrus, Nemo asks if the ocean is in danger. He says that his family heirloom is a divine sword, and that his ancestor used it to defeat an entire army of undead demons. Nemo explains that the sword has glowing inscriptions on it, which are believed to be ancient words that were used by gods. He tells Nemo that if they can find the sword, they can escape this place. Nemo asks the princess to follow him, and the princess follows him. Nemo says that he is afraid that something is wrong with the ocean, because the walls seem to adjust to the position they are in. The princess asks him if he noticed that the walls seemed to move in the right direction, and he says that it looks like hardened blood. He asks if he was there when the sword "swung bloody sword seal" when they were in the desert.
