Hayate joined Delta Flight, where he developed his signature maneuver, the "Immelman Dance". He also possesses "fold receptors" that not only make him immune to the Vár Syndrome, but also enhance his combat abilities when stimulated, which usually happens when his receptors synchronize with Freyja Wion's when she sings.
Hayate is a brash and carefree individual that spent most of his life wandering the galaxy. He has trouble adhering to authority or anything that would hinder his freedom. Prior to the events of the series, he led an aimless life doing a number of odd jobs. Despite his disdain for the military, he joins Delta Flight and develops a passion for flying. His relationship with Freyja Wion and Mirage Farina Jenius also help him realize a newly found purpose in life.
Hayate has severe cat allergy - especially towards Mercats , a breed of cat-like sea lions indigenous to the planet Ragna. Hayate also develops a dance named after him by Mikumo called the "Immelman Dance".
