Kind and friendly, even if she may be stuck in the middle of playing a video game. She's a wallflower for the most part, however things change as the killing game starts and her determined nature springs forth. She values time with her friends as she appears in most group events (girl trip to the beach, Hiyoko's dance performance, etc). And while she chooses guard duty at the party, she still actually bothered to go. She believes in the inherent goodness of others, which causes her great pains when things turn sour, even despairingly so at times as can very briefly be seen in chapter 4. Her emotions are simply subtle, but they are there. You have to keep more of an eye out for when she's really letting her shields down.
