Summary
My own take on Iruma being discovered for having a lack of wings.
Snippets of before shit goes down.
A somewhat crack-fic vibe (low-level)
Alice is blissfully ignorant (of Iruma and his feelings)
People worry (rightfully so)
Iruma is too much of people pleaser
Author put low effort........sorry but not really

Summary
Suzuki Iruma has never said 'no.' Not once. He was possibly the biggest pushover in the world. From shady proposals to outright illegal deals he'd yet to find anything he would decline. No matter how badly he wanted to. It's pathetic, really. Even he knows that. So when his parents– so kind, so polite– asked him if he could please finish a summoning circle for them, he walked into their basement without hesitation.
One glance at the word ‘demon’ and Iruma wishes he was illiterate.
or
alternate timeline where Iruma summons Sullivan and, much like anything he does, things don't go to plan.

Summary
Уявимо, що було б, якби Ірума продали Кальєго, а не до лорда Саллівана через своїх родичів, що захотіли собі спадщину і заразом позбутися "білої ворони" сім'ї. Але ніхто не знав, що в гонитві за грошима вони з'єднають справжню сім'ю

Summary
The Suzu clan was the first to bear a child born of both human and demon blood. From that union came a new demon type known as the Omega. Unlike the brute strength of Alphas or the vast numbers of Betas, Omegas were different. They were gentle, cherished by all, and natural-born nurturers. Any pack led by an Omega was destined to flourish—its members strong inside and out, its cubs healthy and resilient.
The Suzu clan’s patriarch once rose to become Demon King. His reign was remembered as an era of Eutopia. Yet after two centuries of service, he relinquished the throne and entered a deep slumber, conserving his strength to prolong his life as a demon. But that very act became the seed of the catastrophe later called the Promised Day.
This is story of Iruma, born in the "Kalego Era"—a rare male Omega. Though he had the body of a human, in the Netherworld he would awaken his instincts, ambitions, and desires, alongside his classmates. (ABO, KalegoxIruma, Groundic fic, SURE WHY NOT?!!!)

Summary
It'd been such a nice morning.
The weather was lovely, Iruma managed to follow along somewhat alright during classes, and his friends were all pumped up for summer vacation! The only problem was studying, and it was such a universal, normal, problem that- despite the consequences of failing- Iruma welcomed it with open arms.
But of course, all good things come to an end. Iruma had learned that early in his life- and he felt disappointed in himself for momentarily forgetting it.
'It had been such a nice morning' Iruma thought to himself as the uniform covering his back was pulled up, exposing his humanity for all of the Babyls' teachers to see.

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
Kalego has filled over 66 notebooks dictating every step of his success at Babyls. Though he is just a student at this time, by the time he is a sixth year, he will be a successful, highly-ranked demon. And more importantly, the next Guard Dog of Babyls.
Unfortunately, not any of the 66 notebooks mentioned how to avoid the nuisance that his wretched homeroom teacher would be.
Why or why did Iruma-sensei want to make his life so difficult. Kalego wondered why the teacher was just so....abnormal.

Summary
After the Deviculum, Iruma fell irritated. Why, you ask? Well, he has been thinking about why he wasn't born as a demon. Why was he born as a human and have horrible parents?

He also noticed the way his grandpa acts when the name of Demon King Derkila comes up. Iruma can tell that his grandpa cares and is worried about him. He wants to help, but how?
Alikred, who was listening to Iruma's concerns, thinks that the time has come to tell Iruma a secret he has been keeping to himself.

Summary
Bruce rarely goes on work trips, as Bruce Wayne. But as Batman he goes on plenty. So when a work trip came up to go to Japan he thought he would skip out on this one like he did all the others, but something felt like it was calling to him. So he did something out of character and went. It was a trip to check up on the Japanese branch of Wayne Enterprises. Bruce has been to Japan before, it was as Batman so he had to act like he’s never been here. So to keep up appearances Bruce wandered around to the city, soon coming up to one of many forests in the area. It was there he saw something out of the ordinary, a blue haired child that couldn’t be more than 6.
The Child's name is Iruma.
(An AU where Iruma Suzuki is raised by Bruce Wayne at a young age and as the youngest child. Thus, changing multiple things.
I'm still bad at summaries.)
