Summary
Iruma’s eyes inadvertently catch sight of the mirror on the side of the wall in front of him. His blood freezes and eyes widened as he caught sight of a large silhouette looming right behind him. Tall and slender, height that would have had the large horns on its head hitting the ceiling. Large, looming, and long hair spread out like an unholy halo.
He blinks and it's gone.
Then he falls—down and down into the darkness.
_________________________________________________
Iruma has a soulmate he doesn't know and it comes to haunt him—literally. Now he has to traverse the netherworld hiding his human identity, get pulled into schemes years into making, study to pass Babyls, and try to figure out just who is his sleep paralysis demon and how can he kindly ask them to stop terrorizing him.

Summary
“Snap!” Clara cheered, slamming her cards dramatically into the centre of the pile.
Everyone stared at the cards in silence for a moment before Crocell spoke up shyly. “Um, I thought we were playing Chase the Nine?”
“We were,” Lied replied slowly, quickly glancing at his own cards and back at the ones Clara had just placed on the table “That doesn’t even make sense” he comments again.
“Clara, you can’t just invent rules!” Asmodeus snapped. “That’s not how the game works”.
A trip to the Grand Bablys hotel started off all fun and wholesome for Iruma and his friends, but after just one night staying there they were now trapped indoors due to a weird anomaly. As time progresses Iruma begins to notice his classmates slowly starting to act weird, and not the type of weird they usually are. Not to mention the peculiar receptionist downstairs, somethings not adding up here, and Iruma hopes his friends are ok. -

Summary
Despite the fact that it was a throw away line, he couldn’t get it out of his head. "Papa Balam."
Being a father felt like the natural progression of his love for living creatures and cultivating life. One day, that life would be partially made up of him. But it would be better than that, because they would grow into their own person too. It’s part of what makes life so beautiful and precious. The problem wasn’t that he didn’t want kids.
The problem is that he is in no way ready now. So yes, the comment was said in jest but it shook something in him.
Or
Balam hears some of the misfits joke about him being their dad and he panics only slightly.

After being dragged out of class by Balam-sensei, practically thrown into the teacher's lounge, and his humanity on display for a group of demons, Iruma can do nothing, but accept his untimely demise.

Summary
Ah, the harvest festival, a promotional exam for Babyls first years. An exam where students are task with surviving 6666 minutes (Roughly 4 days), where they harvest and hunt for points in the form of devibeasts or magical plants. They are task with surviving these 4 days, but they are allowed to forfeit whenever (and if they're in danger the teachers will come and save them. Can't have too many casualties after all!). It's a free for all with the only rule is you can't cause physical harm to other students as doing so will be cause for immediate disqualification.
At least, it's usually a free for all, though that appears to be a different case for two students from block C.

Summary
I was bored of not seeing many reader inserts for this manga/anime series, so I decided to take matters into my own hands. It is a female POV, and it's is feeding me dopamine to figure out how to write. I will be using another fic to try to keep the plot as on point as I possibly can, however I will not be plagiarizing their work.
Please check out "Welcome to Demon School, (Y/N)-chan!", they are the inspiration for my sudden urge to write. I admire the OC inserts in the story, as well as the way the author wrote the reader. Literally binge-read both parts of their works in a day because it was scrumptious.
ANYWAYS, you, our lovely reader, are an utterly overworked student at a boarding school (Details of where in the human world is left out, so you're free to use whatever location you'd like). After working on several assignments, you barely make it to bed before you pass out. But your dream isn't exactly... normal. And by that, I mean you basically sell your soul to a demon, because apparently another student broke into your dorm and was about to do who knows what to you! Now, you get to traverse the Netherworld while going to school, trying to keep both you and your new brother from getting discovered and eaten!Series
