Haruya Kobayashi attends Alphonso Academy, sporting purple hair and green eyes behind frequent glasses. His reserved, polite demeanor manifests in quiet library reading sessions. Primarily raised by his grandparents, his childhood shyness stemmed partly from familial dynamics where his older brother outperformed him in traditional Japanese dance. Despite this, he admired and aspired to emulate his brother. Haruya harbors a substantial appetite, regularly entering food competitions and consuming meals rapidly. Musically, he plays bass for the band "Red Prince," occasionally referenced as "Dead Prince."
