Kyoko Kirigiri, is a student in Hope's Peak Academy's Class 78th, and a participant of the Killing School Life featured in Danganronpa: Trigger Happy Havoc.
Years later, she is a participant of the Final Killing Game featured in Danganronpa 3: The End of Hope's Peak High School with the other Future Foundation heads.
Kyoko is a stoic, mysterious and intelligent girl who tends to hide her feelings. She usually considered distant and cold and has a calm demeanor and tends to be completely unfazed by most of the events that occur, even at the sight of a dead body, and also seems to be independently investigating herself most of the time having no casualties in the situation. She plays major roles in discovering the mysteries of the class trials, seems to be one of the very few students who look at things objectively and the ones that don't jump to conclusions during the class trials, making her a valuable ally to Makoto.
As seen in Danganronpa 3, Kyoko has changed a bit, with Kazutaka Kodaka considering her development one of his favorite parts in the anime. She has become a lot more considerate of her friends and her demeanor is friendlier in their company. She is seen smiling at them and sharing physical contact, like hugging and holding hands, and she trusts her friends very much. When she's with anyone but them, though, she's still very expressionless and reserved. She is also a bit sharp and annoyed in Koichi Kizakura's company. Being his boss, she is very protective of Makoto, but also admires him greatly.
Kyoko appears in Danganronpa 3 - Future Arc, along with Makoto, Aoi, and Yasuhiro. Kyoko is the 14th Division's leader and is one of the few people allowed to attend Makoto's trial, thus she gets roped into the "Final Killing Game".
until after her big brother Koushiro Kirigiri it's missing for years and she finds out that The Dark Plague killed her brother and she wants vengeance for his death she really cares her brother and she doesn't know about his secret.
