Vadim Ivanochuk (Russian:  Вадим Иваночук; born 19 March 1974) is Masha's alcoholic ex-boyfriend who originally hails from the Russian hip-hop and psychedelic music capital of Rostov-on-Don where he once pursued his career in music. He now drives a schoolbus and stalks Masha when he is able to walk without falling down. He once beat up a cash machine because he thought it called him gay after a particularly routine drinking session.
