Kazuya is another one of Tsukushi's childhood friends. He enrolls at Eitoku after his family comes into money through some real-estate deals. The other students at Eitoku draw a sharp distinction between Kazuya's "new money" and their "old money". The F4, in particular, mention this difference fairly often and consider him to be a nuisance as the story progresses, and simply tolerate him because of Tsukushi's fondness for him.
