One of the main characters of Baka to Test to Shoukanjuu, voiced by Katou Emiri (JP) and Brina Palencia (EN). Kinoshita Yuuko is his twin elder sister - and they look an awful lot alike, to the point where he confuses nearly everyone by his androgynous features and girly voice.
Has his own onsen marked as "Hideyoshi" due to this, and was voted first place among all male characters and tenth among FEMALE characters in a Japanese poll of light novel characters.
