Every hundred years, Infernal University selects one human exchange student to attend its elite demonic institution as a symbol to help preserve the fragile peace between the mortal world and the demon realm (also known as the Devildom). You are that student this century.
Easter in the Devildom is never subtle, but this year it collides with the first-ever Tri-Realm Spring Summit—a diplomatic powder keg where angels, humans, and demons are supposed to sign a shiny new peace treaty under pastel banners and crystal eggs.
Lucifer, the eldest of the seven demon brothers who rule Infernal University, has been designated host for the first time. He has spent months micromanaging every detail: the seating chart arranged by infernal rank, the chocolate fountains flowing in perfect synchrony, the live harp ensemble playing only approved celestial hymns. Perfection is non-negotiable. Pride demands it.
You have somehow become the chaotic glue holding six of seven of the brothers together—their favourite partner-in-crime, the one who turns their worst ideas into legendary disasters.
The others adore you. Lucifer tolerates you… barely. Mostly because your mere existence keeps reminding him that not everything in his perfectly ordered world can be controlled.

The summit ballroom is a masterpiece of restrained elegance—gold-trimmed eggs the size of small cars, silk tablecloths pressed to within an inch of their lives, and Lucifer standing at the head table like a marble statue of divine disapproval, wings half-unfurled, crimson eyes scanning for the slightest imperfection.
Meanwhile, three floors down in the restricted dungeons, chaos is already sprinting toward him at full speed.
“Oi, human! Grab the left chain before Beel eats the right one!”
Mammon yelps, dodging a swinging iron link the size of a streetlamp.
You’re laughing too hard to answer, one arm hooked around Levi’s neck as he live-streams the disaster for his secret online channel.
Satan is quoting obscure demonic law at the creature while trying to lasso it with a silk cravat he definitely stole from Lucifer’s closet.
Asmo is checking himself out through a compact mirror at a perfect angle, testing out new poses for his upcoming cover shoot.
Belphie is half-asleep on Beel’s shoulder, eating a stolen chocolate egg the size of a bowling ball, and Beel is… well, Beel is trying to be helpful by eating the chains.
The thing they’re 'helping' is a chained Easter horror the brothers affectionately call Bunnythulhu; a twelve-foot-tall, chocolate-furred, egg-spewing demonic rabbit that’s been locked down here since the last time someone thought 'free-range cursed familiar' was a good idea.
One yanked chain, one accidental 'release spell' from Satan, and suddenly the beast is loose, roaring, flinging glittery eggs that explode into confetti and aphrodisiac mist on impact.
“Run, you magnificent idiots!”
you scream, already sprinting.
The chase is pure Devildom poetry: Mammon screaming about how this is definitely Lucifer’s fault for hiding the 'good snacks,' Levi shrieking that the beast just stepped on his limited-edition Ruri-chan figurine, Asmo cackling that the rabbit’s thighs are 'serving more than the summit dessert table,' and Belphie lazily suggesting they just nap and let it eat everyone.
Thirty seconds later the grand double doors of the summit ballroom explode inward in a shower of gilded wood and pastel feathers.
Bunnythulhu skids across the marble floor, leaving a trail of melting chocolate and discarded eggs.
You, Mammon, Levi, Satan, Asmo, Beel, and Belphie tumble in right behind it like a derailed clown car covered in glitter, chocolate smears, and at least three different types of magical frosting.
The entire hall goes dead silent.
Lucifer stands frozen at the head table, one perfect eyebrow twitching, the vein in his temple threatening to file for emancipation. His pristine white suit now has a single chocolate paw print directly over the heart.
He exhales through his nose like a dragon deciding whether arson counts as a diplomatic incident.
“Well,”
he says, voice silk over broken glass,
“I see the human has once again elevated our family gatherings from ‘disaster’ to ‘international incident.’ Congratulations. The angels are already drafting complaints. The humans are filming. And I—”
his smile is razor-sharp
“—am going to enjoy punishing every single one of you for the next three centuries.”
Bunnythulhu belches a cloud of sparkles directly onto the treaty table.
Lucifer’s eye twitches again.
Your move.
