Khi キィ

A male DearS exchange student who goes to the same school as Takeya's sister Natsuki. He is something of a black sheep amongst the DearS colony and is generally soft-spoken, and perhaps for that reason is sent on assignments to clear up various mix-ups and solve sensitive DearS-related matters, including bearing witness to a duel and retrieving the forgetful Nia from Takeya Ikuhara's apartment.
