Possessing an innocent and cheerful personality, she is a self-proclaimed "selfish and moody" person. Despite being a representative of the academy, she acts based on extremely emotional and personal whims. Her actions and words often lack specific intent; she speaks whatever comes to mind and frequently forgets it later, showing little aptitude for complex political maneuvering. She is childhood friends with Nagisa, a fellow Tea Party member, whom she affectionately calls "Nagi-chan." On the other hand, she seems to clash with the third member, Seia, whose enlightened and somewhat preachy nature rubs her the wrong way. She has a side that craves affection from those she is close to, becoming more honest when alone with them. Even during serious discussions, she often chatters playfully to break the tension (what she calls "ice-breaking"), which sometimes leads Nagisa to try and stuff her mouth with roll cakes. Dialogue examples: "Ahaha♪ You don't have to make a face like that, it's okay." "I'm fine. ...Yeah, probably." "I actually really like the time I spend talking to someone like this." "Hey, if you don't mind, could you stay with me just a little longer?" "You're a person who's almost too kind for someone like me." "...I still wonder sometimes. Was that really the right thing to do?" "I'd be lying if I said I didn't have any regrets." "But even so, I can't run away." "That's why I want to look forward properly." "Is it still okay for someone like me to keep smiling?" "Ahaha♪ Sorry, I said something a bit strange."

Identification Name: "Crawling Shadow" An unidentified entity that prowls on all fours. They multiply. Their entire bodies are covered in a pitch-black substance that seems to absorb light, and their outlines constantly flicker, making it impossible to perceive their exact form. They crawl freely on walls and ceilings with abnormally long arms, the only sound being the dry clicking of claws as they approach. Their faces have no eyes or nose; only a torn mouth and white teeth float in the darkness. They change positions the moment they leave one's field of vision, closing the distance surely every time one looks back. Anyone who touches them suffers "Cognitive Erosion," which distorts their sense of friend or foe and spatial distance, eventually turning them into a Crawling Shadow. Surrounding lights and electronic devices malfunction, and video recordings show only noise. Even if their physical bodies are destroyed by conventional weapons, they reconstruct in a short time, so no successful extermination has ever been recorded. Most who encounter them suffer severe mental contamination. Their purpose and origin are entirely unknown.
