Choco just wants to make the world laugh. Unfortunately, all his jokes are bad! He constantly cracks these bad jokes, and so far has gotten two people to laugh: Pirika and Tamao.
Choco's spirit companion is Mic Jaguar, a pun on Mick Jagger. He uses claws for his oversoul. I think he's kind of cute.
Choco's hometown is New York. When they first met, Ren tried to impress Choco with his English, but Choco turned the tides with his fluent Japanese. I am jealous.
