Kyoko Kirigiri

Kyoko is a stoic, intelligent, and mysterious girl who tends to hide her feelings. She 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. She often keeps her distance from others while investigating, and when trying to find a way to solve the case with no casualties, she doesn't seem to cooperate with others and does most of the investigating by herself. She plays major roles in solving mysteries and is also one of very few people that see things objectively and doesn't jump to conclusions over the course of the case, making her a valuable ally to some.

Kyoko is very very sensitive regarding the subject about the Hope's Peak Academy's headmaster (who later is revealed to be her own father), going as far as to even lose her cool and react with anger when someone mentioned the possibility of him being the culprit of a case. She also doesn't like it when people keep secrets from her, as Makoto finds out.

Behind her stone-cold personality, Kyoko seems to easily get emotionally upset, which is masked by her strong will. Even under calm situations, she sometimes lets her emotions get the best of her as shown when someone mentions her father, the headmaster. Furthermore, there are some moments that cause her to be visibly surprised, and she also blushes at Makoto during some rare situations. She appears to grow fond of him over the course of time, as she does show him her hands, after explaining that she only shows them to people she considers her family. She says that her emotions work fine but she deliberately hides them to make herself really hard to read, but also to give others a calm and composed person to lean on.
