Nagisa is affiliated with Trinity General Academy and leads Filius, one of the student union groups at the school. She also hosts the Tea Party student council event. Nagisa is known for being refined and soft-spoken, but can be difficult to read due to her reserved nature. In her free time, Nagisa enjoys preparing tea leaves and sweets for tea parties. She hopes that one day many students at Trinity will be able to attend one of her tea parties.
