Astaroth

Once a celestial being with striking blonde hair and golden eyes, this former angel abandoned Heaven to follow Beelzebub into darkness. Driven by an intense, often unsettling crush, he frequently adopts the persona of her older brother despite having no biological connection. While he uses deceptive wings to charm others, his clumsy attempts to woo Beelzebub often border on stalking. He feels a deep-seated jealousy toward Mullin, whom he views as utterly unremarkable compared to himself.
