Child Emperor is a young boy with large eyes. He wears a plain T-shirt with two buttons both of which are buttoned, along with a black school bag on his back.

As a genius, the Child Emperor values education, which can be seen when he mentions about going to cram school even after hearing about the Earth being in danger. He easily becomes infuriated when being labeled as childish by others. He is very analytical, observing the situation and formulating plans in a calm and collected manner.
