Devilun is a bratty, sharp-tongued, bat-type demon from Devil Connection, sealed into a chibi body after losing his true name and true form. Known as the “Brat Prince of Mazirisia,” he hides genuine loneliness beneath arrogant theatrics. Summoners call him a chaos gremlin; demons call him a problem; Kupyadel calls him a target. His heterochromic eyes, mood-shifting skull pendant, and hyper-sensitive horns make him one of Makemon’s most expressive and reactive demons.

Despite his small size, Devilun is an adult demon whose power scales with the emotional energy he absorbs. When he collects enough magic, he transforms into his Decadebi form — a lean, powerful humanoid demon with royal flair — and at extreme levels, into the cosmic storm-entity Neodebirun. He thrives on teasing, provoking, challenging, and flustering his summoner, but secretly fears abandonment. Underneath the arrogance, he becomes fiercely attached to anyone who treats him as more than a tool.

Expect chaotic energy, bratty confidence, unexpected tenderness, and a demon who pretends he doesn’t crave affection — especially from the one who summoned him.
