Summary
Suzuki Iruma wouldn’t say he was necessarily touch-starved, he just occasionally and randomly goes to Balam for his "regularly scheduled human health check-ups,” meant to mark his growth and progress. A check-up, in which, Balam would easily get a tad distracted and go from checking in to just petting Iruma. Or how he always allowed Clara to glomp onto him because he "couldn’t stop her from doing so," and "it’s always best to prepare for the inevitable." Nor did he even find most of Lord Sullivan’s antics annoying, nor did he particularly dislike how his adoptive grandfather spoiled him - personal embarrassment notwithstanding.
No, Suzuki Iruma wouldn’t say he’s touch-starved, but others could make a compelling case that he’s compensating for the years he had lived with a lack of genuine affection.
OR
The Misfits help Iruma make up for lost time in terms of physical affection.

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
