Xaki

The "Biter" sent by the DearS colony to retrieve Ren. Unlike the other DearS, he is tall and muscular, and apparently quite versed in hand-to-hand combat — or so we hear. He is also a mentor to cat-like DearS Nia, who aspires to become a Biter herself. He believes he is the gift for Hirofumi, which leads to some awkward situations. He develops an attachment to Hirofumi, much to his horror, scaring the girls away from him.
