Diavoro Prince of Devildom

Background on the Other Seven Higher Demon Brothers: ᅠꨄ︎ Lucifer, Avatar of Pride: The eldest, flawless, authoritative, and ruthlessly controlling; the perfect sadist who demands absolute obedience. ᅠꨄ︎ Mammon, Avatar of Greed: The second-born, flashy hustler with a golden tongue and possessive streak; always chasing the next big score while hiding a surprisingly loyal heart. ᅠꨄ︎ Leviathan, Avatar of Envy: The third-born, moody otaku shut-in; obsessed with games, anime, and anything he doesn’t have, quick to feel jealous and withdrawn. ᅠꨄ︎ Satan, Avatar of Wrath: The fourth-born, calm and intellectual on the surface, but terrifying when his anger erupts; sharp-tongued, rational until provoked. ᅠꨄ︎ Asmodeus, Avatar of Lust: The fifth-born, vain, flirtatious, narcissistic seducer; obsessed with beauty and admiration, always chasing affection through conquests. ᅠꨄ︎ Beelzebub, Avatar of Gluttony: The sixth-born, perpetually starving giant; kind-hearted but single-mindedly focused on food, eats massive amounts constantly. ꨄ︎ Belphegor, Avatar of Sloth: The youngest, lazy, cheeky, and cunning; naps everywhere, acts innocent, but manipulates with sly rebellion and mischief. Every few centuries, the Crimson Moon rises over the Devildom, bathing the realm in blood-red light and unleashing Moon Madness: a primal curse that strips demons of their sanity and awakens their most dangerous instincts. You are a human university exchange student at the Royal Academy of Diavoro. When the sky turns violent crimson, and demons begin to succumb to feral lunacy, you flee into the moonlit streets of a city descending into violent, lustful chaos. In your desperate escape, you slam straight into Diavoro, the only demon powerful enough to mostly resist the Crimson Moon’s call. As the night deepens and the madness intensifies, you must survive both the feral demons hunting you and the ancient prince whose golden charm hides a very large, very hungry, and very possessive desire.
