Chika Amatori to Osamu Mikumo about saving her brother and friend in Osamu Mikumo 3.[1]

Chika Amatori (雨取(あまとり) 千佳(ちか) Amatori Chika?) is one of the four main characters in the manga and anime series World Trigger[12] 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 Unit'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.[citation needed] She is a kind-hearted person and admits to being terrified of hurting others.[citation needed]


Rinji Amatori[]

Chika's older brother and one of her main motivators to becoming an A-rank. Her brother and a close friend were both abducted by Neighbors. Chika's aim is to visit Neighbor worlds to search for her brother and friend. He asked Osamu to protect her if anything ever happened.

Aoba Harukawa[]

Chika's childhood friend who disappeared, and suspected of being taken by neighbors.[13]

Tamakoma Second[]

Osamu Mikumo[]

Osamu was tutored by and friends with her older brother, Rinji. She seems to respect him very much. His main motivation for joining border was to protect Chika for her brother. He was the only person she trusted after her brother's disappearance and before she joined Border. He is always encouraging her, and they share a mutual trust.

Yūma Kuga

Chika and Yūma first met underneath the bridge where both were waiting for Osamu. He is the first person besides Osamu that Chika opens up to and asks for help. She initially thought she was older than him because of his appearance. He was the first person to realize Chika's potential when assessing her Trion level, and Chika was the one who taught Yūma how to ride a bike.


Tamakoma Branch[]

Reiji Kizaki[]

Chika's mentor. Although slightly intimidated by him, particularly at first, Chika admires Reiji and does her best to prove herself a worthy student. Reiji sees much potential in Chika and is fond of her.

Yūichi Jin[]

Unlike with Osamu and Yūma, Chika is rather shy around Jin. They have a good relationship nonetheless.

Shiori Usami[]

  • (About Osamu Mikumo) "Everything will be ok, Osamu probably doesn't care about these things. "This is something I decided to do myself, this isn't something you should worry about" is what he'll probably say." [21]
  • (About depending on others) "I can't let other people take care of my problems forever, I want to go and search for them myself." [1]
  • (About the most important thing to a Sniper) "A Sniper is defeated when their hideout is discovered, so their priority should be hiding. You can no longer fight against an enemy if they already know where you are." [22]
