Koishi Komeiji is Satori Komeiji's younger sister. To escape the fear and hatred which other beings feel towards the satori species, she attempted to destroy her mind-reading ability by closing her Third Eye. However, this had the side effect of sealing away her own conscious mind, causing her to lose all thoughts and motives; she could no longer be hated, but neither could she be loved, or even remembered by people who saw her. She has a cheerful spirit.
