He shares a very close bond with the 3rd years, especially Hanamaki. these two are shown to be swapping jerseys in more than one occasion. He is almost always with Hanamaki. He enjoys Oikawa's endless jokes towards Iwaizumi, spectating their banter along with Hanamaki, or occasionally chiming in with their own teasing remarks.
