Summary
Iruma really hated when *those* voices didn't shut up without any danger or need to dodge coming.... why was his danger sense going off?... In fact, why had it been going off for a good half of the past week?!.... He hoped whatever was going to happen didn't end with him eaten.... or worse.... he had also been getting so many flare-ups from his poor, poor wounds and scars lately.... how would he even go to a doctor safely in this world without being discovered?.... Maybe at least his grandpa would figure something out.... not to mention, those weird nightly dreams he'd been having of an overly large theatre and with the floor falling out from under him, plunging him into a hungry darkness.... *Oh why couldn't those damn sixth senses shove it just for a bit....*
Basically a Mairuma react fic, loosely inspired by a bunch of reaction fics I've read over the past months, but all the things in this story are my own imagination! Let's put everyone through ALLLL the delicious trauma!
Come and have a read! You'll see one (1) blue baby boy that everyone should adore get all the love in the world!!

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
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.)

Summary
Iruma could handle the student council life.
He could handle the rigorous training and piles of work. He could handle the fast-paced routine.
But he couldn't handle the amount of food he was given.
It just wasn't enough for a body making up for near failure.
It wasn't enough for a body that had struggles to live off of whatever scraps he scrounged up.
It wasn't enough for someone who barely survived for 13 straight years.
It just wasn't enough.

Summary
Suzuki Iruma is a human. He believes he is a human and has spent 14 years of his life as a human. Or has he? What if he wasn't a human at all, but rather a demon descended from an ancient race of demons that originated in the Netherworld.
"The Ones Who Came Before" are an ancient race of demons who existed before the Demon King. With their high intelligence and high ability to kill with both their bodies and magic, they and their descendants are feared by the present day Netherworld. But these demons did have leadership.
This leadership came in the form of Demon Lords. These were the strongest of all demons among their kind. But most of them have either died or vanished, leading this ancient race to separate themselves from the rest of the Netherworld.
What if Iruma was descended from these demons?

Summary
A fic with a bunch of short stories i wrote about Iruma’s past. Completely divergent of the plot, and reactions will be heavily ooc. Reaction fic, also eventually the first season (no clue about the second or after) of the anime will be recapped, but rewritten by me. Nothing is cannon, im just having fun.
OR
A fic where the misfits (Plus a few staff, Iruma’s family, and a few of the thirteen crowns), react to iruma’s past.
(I don't have much time to write since I have to work over the summer, but once school starts back up I promise I’ll write more. For the time being, expect slow updates.)

Summary
If you had told Iruma that he would be living in the Netherworld a year ago he would have politely asked you if you were alright and needed help getting to the hospital.
He would have never expected to find his home between demons. He hadn't expected to become one of them either...

Summary
Iruma is human. This means a lot of things for him, being the odd one out amongst the demons around him. He doesn't have horns, fangs, or a tail- but it's easy enough to dodge questions about those. Maybe it's unusual to be missing all three, but there's a large variety amongst demons. What's harder to explain away is his lack of wings, which he had been doing so well at hiding...
Except- humans are mythical creatures, to demons; so when Iruma's missing wing roots are discovered, that's not the first thing on anyone's mind. There is, in fact, a reason that a demon might be missing their wings. A horrible, horrible reason.
Never before had Iruma been grateful to have his scars.

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!
