He then tied Joe on his neck and went to meet "Bouzu", his owner and tripped into the floor, causing Joe to fall into the floor too. Joe then draws Chomolanmacho and he tries to capture it but fails. so he drew a sign that refers to Joe falling love with Uraraka Momo but Joe burnt the sign by using Deckie as a eraser, which caused Momo to come into the scene. Keshikasu-Kun was then fetched by an eagle to its nest, resulting in his owner to fetch him back. He then challenges Joe into a duel.

In the duel, he put himself and Deckie in inflatable underwear and when a shield is broke, the underwear inflates.
