Heheheh, before anyone starts asking questions about why I'm tackling ANOTHER fic when I have about a dozen others that I should probably get back to, I'd like to say that this chapter was NOT written by me. No, that great honor, as well as this idea, goes to Hazard Overflow on Ao3, Beta by Crystal Quill. I found his story on the site, and he was in need of a co-author to bounce ideas off of, so I kindly offered my services. It's been great to write something together with someone. We've already worked on the 2nd chapter together, so that should come out shortly. Hazard was kind enough to allow me to upload his fic on my profile. Thank you, kind sir, you are the best!

Yeah, I've been a HUGE fan of Welcome to Demon School, Iruma-kun for a while. It's honestly the funniest and most adorable anime I've seen, so it's a HUGE pleasure for me to work on this with someone.

Enjoy. I own nothing, not even this chapter.

Chapter 1: What a day


Izuku walked through the front door, poking his bruises with a grimace. His last run in with Kacchan hadn't gone well.

"Mom, I'm home!" he called out, carefully moving his clothes so the bruises didn't poke out. He smelled cooking, smiling at the homey feeling it gave.

"Welcome back, I just finished cooking!" she shouted back, her voice sounding a bit hoarse. He straightened at that, slowly moving into the kitchen area. He looked at her, Inko Midoriya, a plump woman with kind, and now red and itchy, looking eyes.

"Mom, are you okay?" he asked with worry.

She waved it off. "Yeah yeah, I just burnt myself when I was messing with the vegetables, you know how often I cry," he laughed, sounding like she had been crying for a while. "I made us katsudon for dinner."

This sentence caused a wide smile to appear on his face. "Awesome! Thank you mom." He said as he hugged her. "I got an A on my test this week." He stated to her, pride on his face as he took a bite.

Inko smiled brightly. "That's wonderful dear. You've always been so smart," she praised him, causing a blush.

"Well I've never gotten top marks, that's usually Kachan," he said, embarrassed. Izuku finished up, cleaning his plate as he walked over, giving her a hug. "Thanks for the meal. I'm going to do some homework then head to bed. Love you," he said as he left the room.

"Love you too Izuku!" she shouted as he made his way to his room.

Izuku let out a sigh of relief, able to lean down onto his chair. He looked down at his bag, pulling out notes from school, along with a burnt notebook, pulling it open on a fresh page. "Alright then, Mt. Lady revealed a new super move today …" And with that he began to feverishly write. All in all, today was an okay day.

Inko's smile dropped as she watched her son enter his room. She went over to the counter, opening a drawer and pulling out a letter. She sat down on the table, looking over the contents of it.

'To Inko A. Midoriya. Due to an over hiring of new staff, the Mustufasu Hospital has had to make the tough decision to let some of our people go, and have re-evaluated all members to make the best decision possible for our patients. While we have enjoyed having you on our team, you fall short in terms of qualifications necessary to continue employment in your current role. As we have no other open positions, we wish you luck in your endeavors and hope that you use us as a recommendation for future employment.'

She reread the message over and over, trying to find any mistakes in identification or meaning. There were none. It wasn't a false note and there was no way to mistake what it was saying. She was fired. She was unemployed. Tears began to form again, but she made no noise.

"What are we going to are no other hospitals in the city looking for hire," she muttered, staring at the phone as she remembered the conversation from earlier. The shouting and yelling, the complaints, and then the silence … the awful silence. Hisashi just said he would 'think about it' and hung up.

"The bastard– a quirkless child is nothing to be ashamed of. He's so kind and generous ,so smart … oh Izuku." She put her head between her hands. All in all, today was a terrible day.


Hisashi stared at the phone he tossed onto the floor, growling. He can't believe that bitch is going to make him spend all that money, and on a worthless son too. He began pacing the room, walking across it while clenching his fist.

He couldn't just not pay, he'd get sued in court. And Inko may have not cut it out to be a lawyer (she cried whenever anyone yelled at her), but she knew the law well in and out. Frustrating, he thought as he idly grabbed a book.

He was going through his collection earlier and found something he picked up at a garage sale by the Suzuki family down the street back at their place. He scoffed, lazily scrolling through the pages to numb his mind. Seriously, 'Demon Summoning for Morons', what kind of ridiculous name was that?

As Hisashi scrolled he cut his thumb on a page, dripping blood onto a circle. "Fuck, does everything in my life want to be a cunt at the moment!" He shouts, tossing the book away. He glared at the cut, only turning away when he saw a red light emanating from the book crumpled on the floor..

The book soon became a pillar of fire, Hisashi's rage manifested in physical form. The blaze was unnatural as it, instead of a warm or burning sensation, caused a cold chill to settle over the room, the sparks matched with steps as a shadow slowly grew and grew, sparks fitting into a purple suit, wrapping around the fire. Animals scratched, an image of a bird dying in the blaze as it's large skull now tied a fluffy collar. The flames now died down, showing Hisashi a wrinkly face, mustache on the thing–man's lips and small glasses on his eyes. A bald head having small embers die down into horns on top of the head, going over pointed ears, the chill only got worse, now coupled with a gravity as the man, who's presence demanded attention, stared impassively at the bug in front of him.

"Speak to me your demand, human," The man–no, the demon commanded. Hisashi quickly realized what was going on, sweating at this man's demeanor and the threat to his own safety. Thus, he began to get his point across fast.

"I'm running through a bit of a money drain … and I'd like some help making that problem disappear," he stated as calmly as he could.

"I see, is this a financial problem or am I murdering an enemy." The demon asked as he stared down, casually enough to mistake it for a question on breakfast. Hisashi gulped at the calmness this thing emanated.

"It's my family, my wife lost her job and now I need to give more money to her and my worthless brat," he growled, finally getting into the spirit of things.

"Family?" The demon asked with a head tilt, but nothing else. "May I see a picture of who to target?" That made sense. Hisashi went and grabbed an old photo album and handed it to the man.

"The boy's older, but he should still be recognizable with the older pictures." He stated. The demon nodded, flipping through the pictures slowly at first … then faster and faster, a desperate look in his eye as he closed it.

"How old is the child now?" He asked, staring into the human's soul.

"He's fourteen," Hisashi replied.

"Fourteen years old, the perfect age." The demon gave a smirk and a chuckle. Hisashi quickly realized that this thing … had a preference for young kids, but hey, he wasn't going to knock hell for what went on there.

"So can you take care of this situation?" Hisashi asked the demon.

"I'll do you one better actually." The demon aimed his palm at the ground, muttering in language not meant for human ears, fire burning as with power as space distorted. It died down to reveal a chest, exposed to reveal riches from multiple eras. "I shall give you riches to live the rest of your days in peace and luxury. In exchange …" He pulled out a burning contract, written in blood and produced a feather from his coat. "You must sell me the souls of your wife and son."

Hishashi blinked for a few seconds. He then gave a vicious smile. "Done deal," He agreed, signing the contract without any hesitation. The paper burned away, the demon grinning victoriously.

"Well then, enjoy your life, Hisashi Midoriya," he spoke, walking away as he faded away into nothing. Hisashi looked down at the treasure, knowing he could get tons of money if sold right. He smiled brightly. All in all, today was a good day.


Lord Sullivan, one of the Three Great Heroes of the underworld, Chair-demon of Babyls Demon School, and the top candidate for the title of Demon King, stared down at the two tied up and unconscious humans, waiting for them to wake up.

They eventually groaned, eyes blinking into consciousness … then screaming at their situation, noticing the rope and paper on said rope, saying 'sold'. This continued for a solid three minutes. "Are you done?" He asked, they froze and noticed him, now screaming even louder.

"Who are you!?" The child asked, looking scared.

"I am Lord Sullivan, a demon." Wings grew from behind the man, black and bat-like, lightning shining the room to create a deep shadow behind the man, looking as if they were gazing on the devil himself. "And your souls are mine."

"Why, why us!?" The mother asked, shaking in her boots. She likely didn't believe him, but it mattered not.

"Hisashi Midoriya sold your souls to me," Sullivan spoke, pulling out the contract out of flames. The child looked with a twinkle in his eyes, despite the fear in his body. Sullivan smirked at this. "Are you not Inko and Izuku Midoriya?"

They froze in place, eyes wide and unbelieving as they stared at the contract. "That … bastard." The woman, Inko, gazed at the paper with a blank face, fury in her eyes. The demon grinned, putting it away.

"Now then … onto matters of what I wish of you." He spoke, energy pouring out of his body. Energy washed over the two humans as they were paralyzed with an instinctual fear. "Now I shall ask this once and only once. Will you …"

Sullivan leaned down, arms extended as the lights turned on, revealing an expensive looking room full of kid toys. "Be my family, as my daughter and grandson!?" he screamed. The two had a look of shock on their faces, unable to comprehend what they were being asked.

"You see," the demon starts, suddenly looking embarrassed. "I've been single all this time. It's always been my dream to have a grandchild." He gets on his knees as he claps his hands together. "My friends always brag about their grandchildren in my face and it makes me so jealous! And I can't just break up a family, so I wanted you both. I'll give you both anything you want and spoil you to death, so please, please be part of my family!"

Izuku blinks in bafflement. "But … we were sold weren't we …"

"I'll respect your wishes, it wouldn't be right to just force the roll onto you both," Sullivan stated, now looking with hopeful and pleading eyes.

Izuku is about to say something, but is cut off by Inko, who has a very … serious look on her face. "If we do this … will we be safe and secure?" she asked, eyes filled with determination.

"Yes yes, of course, I'm not going to allow my family to suffer," he nods. Inko looks over to her son, a silent conversation in their eyes as she turns back.

"We accept." she nods. Sullivan shouts with joy, hugging the two after breaking their ropes.

"Thank you, thank you, you both made me so happy! If you'd said no I'd have eaten you while in tears!" He shouts, oblivious to their horror. All in all, today was a perfect day.
