Chika Amatori is one of the main protagonists of World Trigger. Chika is very shy, and rarely says much. She has very few friends, because she voluntarily distances herself from others. She believes that she'll just get hurt when those she gets close to get kidnapped by the Neighbors. She is really patient and serious and can concentrate very well, but she has low confidence and can't see her own potential. After meeting Yuuma and joining Tamakoma Branch, however, she starts warming up to others and becoming more sociable and confident on herself. She is a kind-hearted person and admits that she is terrified of hurting others.

As such, she has yet to directly fire upon the opponents in the rank battles.
