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. At the beginning of the anime, Kyoko often keeps her distance from the other students while investigating. She plays major roles in solving mysteries of the culprits in Class Trials and is also one of very few students that see things objectively and doesn't jump to conclusions in the trial. She is very very sensitive regarding the subject about the Hope's Peak Academy's headmaster, going as far as to even lose her cool and react with anger sometimes. She also doesn't like it when people keep secrets from her. Behind Kyoko's stone-cold personality, she 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. Furthermore, there are some moments that cause her to be visibly surprised. Kyoko 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.

If you could sound similar to her English VA, Caitlin Glass, that would be great, but it is not required!

I don't have any English VA examples as there is not many I can find on Youtube, so if you could try and match the dub voice, it would be great, but again, it is not necessary.
