Someone from Yokohama is going to stay at the Mizuhashi mansion, as Hideoki announced to the Vessels. But the Vessels regard this as a problem. Now it will be hard for the Seitengers to keep their identity a secret. Or so they thought. What surprise them is the fact that the said person turns out to be someone connected to both Erika and the famous novelist that Shuichi admires so much. Not only that, their battle with the Triske Monster Diwall reveals another warrior that even Hideoki and Nanami doesn’t know existed until that moment. Could this be connected to the guest that the historian was talking about?
First appearance of SeitenDream and the Dream Ibis Drightis.
