The Nura Clans have a unique strategic fortress called Takarabune, which resembles a giant boat with arms extending from its sides. It has the ability to self-repair when resting. Rikuos forces utilize it for travel to Kyoto. During their journey, they encounter an attack by the first wave of Kyoto yōkai, causing heavy damage to Takarabune. As a result, it crashes into a river and is left there to recover.
