While Hasebe is away on an expedition, Kikkou Sadamune and Sengo Muramasa compete to see who will take care of Master in his place. Hirano finds Uguisumaru writing about Ookanehira and asks to learn more about the newcomer.

Taroutachi, who is tall even for a Sword Warrior, has trouble with his size in his day-to-day life. In the midst of the hot summer, Mutsunokami comes up with a different kind of sparring to help everyone cool down.

Houchou goes fishing with Urashima and the others after he arguing with Ichigo Hitofuri, but they end up falling asleep and wake up not knowing where they are... Oodenta is afraid his spiritual power is scaring away the animals.
