Ueki's next opponent is Onimon (full name - Oniyama Monjirou), who can turn the dirt he kicks into cannon balls. This guy is different from all the other guys, and it's not because he likes to shorten names.

The fight between Ueki and Onimon reaches its conclusion. A week afterwards, Onimon trains Ueki so that Ueki can fight a stronger enemy known as Kuro Kage, one member of Robert Haydn's Ten.
