Ibitani calls Machimiya "Miya". He admires him greatly, praising him for his skill and hate-filled technique, and seems to care about him a lot, understanding what Machimiya went through to focus on the Inter High. They've known each other since before Machimiya became obsessed with crushing Hakone Academy. Ibitani easily gets emotional over Machimiya's everyday actions. In one scene, he dramatically and silently weeps over watching Miya break up with Kana.
