Hayate possesses "fold receptors" that not only make him immune to the Var Syndrome, but also enhance his combat abilities when stimulated, which usually happens when his receptors synchronize with Freyja Wion's when she sings. Hayate's Siegfried unit is colored in a white, blue, and gray scheme and his callsign is "Delta 5"; later in the series, he is reassigned as "Delta 4" and would later be issued a new VF-31J with a blue knight marking on its back. He is nicknamed "Haya-Haya" (ハヤハヤ) by Makina Nakajima. Hayate wears a special fold quartz pendant from his father, Wright Immelman.
