Kūi Dōtonbori

Kūi is described as a muscular man who is just as tall as his son is fat, which is to say he is very tall. He does not wear a shirt in the novel.

Kūi and his son, Daore, travel the land taking part in food competitions wherever they may occur. Kūi has competed against Chōji Akimichi during several prior contests and has lost to Chōji each time. For this reason, he considers Chōji his rival.
