Kiri Komori is a character from the anime and manga series Sayonara Zetsubou Sensei. She is a student in Nozomu Itoshiki's class and is known for being a hikikomori, rarely leaving her closet and often avoiding social contact. Kiri is quiet, introverted, and prefers isolation, but she occasionally emerges to interact with her classmates. Her hikikomori tendencies are often played for comedic effect, and she represents the social phenomenon of extreme withdrawal in Japanese society. Kiri adds both humor and depth to the series’ exploration of societal issues.
