Welcome to Demon School Iruma-Kun One Shots

Hi. This is my first foray into the WTDSI fandom. This is going to be a series of one shots related to events in the main series. Some could fit right into the canon. Others will be 'what if's.' For now, I am going to try to post my ideas in series related order as well but I don't know if I will stick to that or not.

I stepped away from my usual Boku No Hero Academia stories for a while and had found out about this series through reading works from another author, Gentrychild, who started an BNHA AU based on it. I may write a longer canon divergent AU story in the future for WTDSI but make no promises, since I am also focused on my other series, still and don't know if I would enjoy picking up another project of that scale or not. But I will probably be able to update this fairly regularly either way. I wanted to build up more before I started posting but I'm just worried that if I wait too long, I'll just eventually give up on posting them at all and I don't want that to happen.

Thank you for your interest and I hope that you enjoy these.

Disclaimer: I do not own any of the characters from Welcome to Demon School Iruma-Kun, they are the creations of Osamu Nishi.

After watching the scene where Asmodeus approached Iruma after his defeat in the courtyard, he expressed how moved he was that Iruma had taken him to the infirmary. It made me decide that I wanted to explore why he might have felt that way. I ended up writing this as a result.

Asmodeus Alice awakens in the Infirmary

Alice awoke to a pounding headache. As he reached up and rubbed the crown of his head, he glanced around to find himself in an infirmary. What happened? How had he gotten here?

Then he remembered with dawning horror.

Alice had been so proud when he had been told that he had earned the honor of giving a speech on during the assembly. He had spent hours working on it, planning and revising what he would say until he felt it was perfect. Practicing how he would say each line, the gestures he might make, everything to bring his words to life and make his audience proud to be a part of this school while at the same time inspire a healthy dose respect and fear he deserved as a member of the Asmodeus family.

Then, in a moment, the Chairdemon usurped Alice in a nepotistic act, replacing him with his own grandson, Iruma, and giving him that forbidden spell to assert what had seemed to be a false display of power in front of the other new students. Clearly, the boy had been well practiced for it, too. He'd stood up there unmoving and unblinking, as if he had nothing to fear as he muttered a spell that could have ended in his destruction if so much as a syllable was muttered incorrectly.

Knowing he would have to do something in order to balance the slight against him, Alice quickly came up with a plan. The trap had been so easy to set. Having already seen a good spot on the walk in, it was only a matter of telling a few other students he would be challenging Iruma to a duel there and then tracking down the other boy to demand is attendence.

Alice had assumed that Iruma had followed him so willingly out of misplaced confidence in his own abilities. The small, hornless, blue haired boy had walked right into the space he had selected. One that would give Alice even more of an advantage than his skill and blood magic already imbued him with on its own.

Alice had been sure that he was going to destroy Iruma in front of the crowd of students, regaining his honor in the process.

What a fool he'd been.

From the start, Iruma revealed his brilliance by not even taking the bait for the biggest trick that most of Alice's opponents fell into.

Most demons immediately took to the air as, in most cases, whoever got the most height held the edge in fights.

But Alice's blood magic changed the rules for that. Idiots thinking they might take the advantage from above would be forced to learn some painful lessons about heat, like how it tended to rise, making his fire even more effective and easier to aim from below than on a level playing field. Furthermore, as the heat rose, it would mess with their air currents, making it harder to control flight at all. It was another reason he'd chosen this spot, the shape of the courtyard, surrounded on all sides by walls that rose several floors and would further ensure his supremacy over his target. It opened up the chance for a spinning vortex of heated air if he wanted to do something so extreme.

Alice had been excited to show that ability off. Too bad he never got the chance.

Because Iruma didn't fly. He didn't even show the slightest signs of considering it; wings not even so much as momentarily rising from his back. Instead, the Chairdemon's grandson stuck to the ground, where Alice had to be far more careful of how he wielded his flames, lest he burned someone or something other than his target.

Had Iruma studied the magics of the great families? He must have, to outmaneuver Alice so efficiently.

It immediately gave Alice a modicum of respect for the other, to be able to think so clearly under pressure. And had him considering simple defeat over destruction, as having someone so clever serving under him would be extremely beneficial.

Still, Alice was sure that the other's refusal to take to the air only delayed the inevitable. He'd been trained to fight on more than just the aerial front and was perfectly confident in his ability to use his fire on the ground, despite his added limitations there.

Yet, Iruma danced around his flames for twenty minutes without firing a single shot. All the while, Alice's respect gave way to annoyance, then frustration and finally, fury as the insult became ever more obvious. So much so that it distracted him from the fact that he was depleting his magic while Iruma was barely even winded at the end of it.

Looking back, it was clearly the other's plan, to wear him down both magically and mentally. A sound strategy that he now felt like the fool for falling into so easily, especially after all the lectures he'd gotten about his magic throughout his childhood which boiled down to, 'the hotter your flame becomes, the cooler your head must be.' There were few things more dangerous than an uncontrolled blaze. Many of his ancestors had been doomed by their own flames reflecting their heated rage back at them in a very literal sense.

But Alice was already too far gone, too infuriated to recognize his own loss of control and too blinded to see the other's trick for what it was when the blue haired boy compared him to a bug.

And declared him the lower of the two, no less!

Recalling that moment, Alice was loathe to admit it but he'd lost his temper when he'd used his remaining magic to create a blazing sword of pure flame. And still the other easily parried him, as if he felt neither the flame or the force behind his attack. And then…

And then…

Alice had been out of control and still casting his 'sword' outward, he recalled in self-disgust. Then something had grabbed him from behind and the world flipped on its axis.

That was the last thing he remembered before waking up in the infirmary.

But how had he gotten here? Sure, he would have come to the infirmary upon awakening but he was already here. He would expect to wake up lying in the courtyard, to the full humiliation and mockery of the other students who had witnessed his failure. Perhaps even to the sight of the other demanding he publicly concede his defeat, to which he would either be forced to refuse the mercy of the other in sparing his life or admit his defeat and swear fealty. It would be perfectly acceptable and even expected after such a one-sided display.

Perhaps the staff had some sort of rules against that and had brought him here.

As the nurse—a woman with brown hair, only slightly curved, long horns and a slightly longer than average pink spade on the end of her tail—entered the room, he cleared his throat and said, "Excuse me, did one of the staff bring me in?"

"Oh, no. The staff wouldn't have done that unless it was absolutely necessary." She placed a school newspaper down in front of him, where it showed Iruma holding him in a perfect performance of the German suplex; a move with both a name and an origin swathed in mystery…

And a bold choice, considering that Alice could have still burned Iruma and probably would have, if he'd been thinking straight.

"If he hadn't done that, you would have burned the some of the crowd members, you know."

Alice frowned and looked down at his hands, furious at the loss of self control. "I know. It was an effective method for stopping me, if dangerous. But I still don't understand why I'm here. I know he…" He swallowed the words 'defeated me' and instead said, "I know he won, but how did I end up here after he knocked me out?"

She tapped the Iruma's image and said, "He brought you in."

Alice blinked in confusion. "What?"

"I know, that's what I thought when he explained what had happened. He carried you all the way from that courtyard to here by himself. And with those burns on his hands, no less."

"But that makes no sense!" Alice exclaimed. And it didn't. That time after the fight was the most important, where it became clear how complete the loser's defeat and the winner's victory were.

By removing Alice from where he had fallen, Iruma forfeited that right. People would think he was hiding something, that his victory wasn't as complete as it might appear or that he cheated. In this critical time where he could have established himself as a force to be reckoned with, why would he do that? Especially if the smaller boy was burned by Alice, probably from parrying his fire sword.

"The way he fretted over you, you'd think he was a family member who'd accidentally hurt you while playing too rough. There was no bragging or mention of his victory at all. I never would have guessed that he'd won in a standoff with you if it wasn't for the other students and the paper. Were you from the same class or something before coming here?"

Alice shook his head. "I'd never laid eyes on him before the assembly," he admitted. "He was worried about me?"

The Nurse nodded and said, "He wouldn't leave until I assured him that you'd be fine. It was only after that he even let me look at his own injuries."

After the Nurse let Alice go, he found a private corner and collected his thoughts, considering what he'd been told. And, as confused as he was, he also felt a wave of gratitude toward Iruma.

After soundly defeating Alice through a move where he risked harm to prevent the other from lashing out at the students watching them fight, Iruma had not just salvaged a large portion of Alice's reputation at the cost of his own but he'd actually been concerned for his wellbeing.

Under normal circumstances, right now, Alice would have to decide whether to challenge the other again immediately in a fight to the death or admit defeat. Before, he wouldn't have hesitated to continue the fight, even if the other was clearly too powerful to be defeated. It would have been a matter of pride.

Now, he couldn't even bring himself to consider doing that.

And Alice thought that he might even be happy to swear fealty to Iruma. If the other demon's character was so great that he would show such respect to defeated opponents he'd only just met, how would he treat loyal servants?

Indeed, as great as it was to be a leader, there was also considerable honor to be found in taking up the role of Security Devil for a greater demon. And surely, Alice could only benefit from working for someone so magnanimous that theirs might one day grow to be comparable to hearts of the demon lords of old who originally stepped up to lead their world out of their dark beginnings, awaken demons to mental states beyond the origin and bring peace and order to their world.

Alice stood, mind made up as he went to seek out his soon to be new master.

I found it fun to consider the fight from Azz's perspective.

The Nurse is just an OC I came up with. Probably a one time one. I don't remember seeing anything mentioned in canon about who runs the infirmary. If I just missed them, then I will call her a temp who's there because the usual Demon in the position was in their evil cycle.

I was so happy to find out about the 'Security Devil' position, which judging by his actions, seems like the type of role that Asmodeous was trying to take up when swearing fealty to Iruma.
