Chika Amatori (雨取 千佳, Amatori Chika?) is one of the four main characters in the manga and anime series World Trigger and the main heroine of the series. She is a B-rank Sniper and member of Tamakoma Second.
Chika has short black hair with an ahoge in the middle of her head. She also has violet/purple eyes.
As a C-rank agent, she has the standard white C-rank border uniform, but with pants tucked inside themselves and lighter stripes, which seem to be the standard for female agents. She also wears a jacket over her uniform.
As a B-rank agent, she wears a uniform similar to Osamu's, but with a jacket with a more symmetrical design, having no shoulder guards and a suspender-like detail starting on the top of her jacket's right shoulder, ending at around the height of her waist, connecting to a horizontal line. Also connecting to this line are two holsters, on either side of her jacket. The sides of her jacket's sleeves have thin black stripes that become thicker on her shoulders, surrounding the Tamakoma Branch emblem. She also wears her collar folded, unlike Osamu and Yūma who leave it up. The jacket is bigger than her body, and covers her black shorts. Her Squad's emblem is located on her left chest. She wears gloves longer than Osamu and Yūma's, and they extend over her jacket's sleeves. She also wears knee-high boots with knee pads.
Chika is timid 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 Yūma and joining Tamakoma Branch; however, she starts warming up to others and becoming more sociable and confident in herself. She is a kind-hearted person and admits to being terrified of hurting others.
