Koji

English voice actor: Joanne Vannicola
MEDABOT: Sumilidon
AGE: 10
SCHOOL: Rosewood Private School

Koji is your spoiled little rich boy. He considers Karin his girlfriend and gets very jealous when others (especially Ikki) pay attention to her. His medabot is very tough, but Koji has enough honor not to take advantage of anyone.

By appearances, he kind of reminds me of Ken from Digimon. What do you think?
