Jirousaburou Ichijou (一条 次郎三郎,Ichijō Jirōsaburō?) is the butler of the Tachibana family.
He worked as the host during the gambling match between Saki and Mikoto being held to determine whether Wataru would stay in the United States with Mikoto or go back to Japan with Saki. Sakuya asked for his help in order to stop the match, which was heading into a negative and embarrassing outcome for her, indicating that he used to be a person with a lot of common sense; but Mikoto, countered her reasoning indicating that he is a lolicon, which he himself confirmed.
