Summary
If you had went up to Naberius Kalego and told him that he would be summoned to the human world by incompetent parents who wanted to sell him their son, Kalego would’ve either flung you across the room with Cerberus, yelled at you for wasting his time, or asked where you had gotten drugs strong enough to induce such thoughts because he wanted some. Life with Opera and the Chairdemon warranted some after all.
But now, with a rather petrified human fledgling in his room, Kalego wishes he had taken that made up warning seriously.
———
Basically another ‘what if?’ Where Kalego is summoned instead of Sullivan to be sold Iruma’s soul, most of you have seen plenty of these and I’m getting brain rot from them so I’m here making my own. Let’s see how long this’ll last before my depression takes this fanfic away from me:’]
Also this should be mostly canon compliant, but I don’t know how this’ll end up. Also also this fic will showcase a lot more of the misfit class because they’re underrated, I need more fanfiction with the misfits!

Summary
Despite what life, or rather his parents, threw at him, Iruma always pushed forwards. He would not give up, for giving up would get him killed. Yes, Iruma was accustomed to fending for himself by himself and this was a fact that would never change.
That was, until his parents decided to try out the art of demon summoning.
Iruma was raised on his own self-dependency. He never had anyone else to rely on, and was consequently forced to learn that he could never trust anybody around him.
However, once Iruma is transported into the Netherworld he starts to realize that the people around him, despite their demonic nature, are the most trustworthy people he has ever met.
It would have been helpful for Iruma to realize this before the evidence of his poor childhood was put on display for all the adults around him to see.

A lack of wings fortunately doesn't automatically mean human. Unfortunately for Iruma, it means something far worse for demons.

Summary
“I’m pregnant.”
The words were like a spear through the chest. “What?”
“I’m carrying a demon child.”
Kalego sat up, head spinning. “That shouldn’t be possible.” They were entirely different species after all.
“And yet, it is.”
Or: Iruma’s mom summoned Kalego as her familiar first and Iruma is Kalego’s son—a half-human, half-demon cambion. 15 years later and Kalego never thought he’d get the chance to meet him until a certain blue haired boy gave a speech at the Babyls opening ceremony.

Summary
"When a human tries to summon a demon, it is the nearest demon to them that appears to them."
So in this case- It wasn't Sullivan who got summoned by Iruma's parents when they were secretly sacrificing their own son-But the missing Demon King "Derkila"-who just so happened to have been vacationing/hiding in the human world.
Because Derkila doesn't particularly enjoy or even like the taste of human flesh- he decides to adopted Iruma instead.
The kids now forever bonded to him now if he doesn't eat- and his lonely with out his friends and family- so why not have a kid to teach and take care of?
He wants to show off his precious boy to the whole Netherworld!
His boy...
His alone....
OOHH!! Naggy Sully would cry rivers over how jealous he was about to be!
But even with all that, Derkila is happy that he's not alone anymore...

Summary
Kalego hated troublesome things. That's why, when he's somehow summoned by two human buffoons to sell their son in exchange for money, he decided he would simply get rid of them. Yes, this decision did not at all change when said son walked in, horrified as his supposed parents eagerly tried to pawn him off. He was going to crush them all, find a way back to the Demon World on his own and—
"You said you wanted money, correct?" Curses.
A story in which, instead of a Demon King, Babyls raises a Guard Puppy.

Summary
After a mysterious accident, the Misfit Class's feared homeroom teacher, the school's resident gentle giant, and the Sullivan household's sole servant get turned into children. To keep this a secret, the Misfit Class (mostly Iruma) volunteers to watch over the three to keep them safe until a way can be found to return them to normal.
How will this work out for our ever helpful protagonist?
Poorly, most likely. But it won't stop him from doing his best!
