Akemi Nakatani is the Ultimate Chess Player. He is standoffish and tries way too hard to act like an adult. With others, Akemi can be rude and seems to think higher of himself. Especially with Kyoto, Akemi can be seen as a bully, not afraid to put others down to boost himself up. 

He hates Monokuma and often questions his judgment, pointing all different kinds of holes into the Killing Game. Akemi can be smart but only uses his genius when it can service him.

Akemi has a noticeable hatred of killers that had to come from somewhere...
