Liquid

Liquid, who once (albeit unwillingly) served in the Ganma army’s elite battle unit, now lives on Papuwa Island as Papuwa’s housemaid. Though he seems forced at times, and though the others don’t seem to care for him much more than a maid, deep down they really do respect each other (even so far as promoting his status to “Papa” for Father’s Day). Once the Shinsengumi are introduced, he is constantly hounded by Umako, the only woman on the island and quite possibly the most manliest looking character in the show. (Wiki)
