Summary
Iruma has suffered a lifetime of hardship, probably around seven of them—if you'd like to get technical. And, at fourteen years old, Iruma Suzuki believes he's about to lose that life.
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.
(A retelling of chapter 63, a grounded AU)

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.

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
Tellur wanted to live his second life with his mother peacefully on their small farm, it didn't matter all that much to him that he now had talons and wings and claws and the ability to do magic. That was cool as hell! Until he figured out the reason for his new species being that he was isekai'd into his favorite manga.
... maybe it shouldn't have taken him fourteen years to realize, but in his defense his memory's still really spotty!
~
Something that he learned quickly was that his current parental figure was fond of throwing him. Literally. He would get tossed fifteen feet in the air before she would catch him again. It took 24 times before he figured out what she was looking for. As he was falling back to the ground for the 25th time wings unfurled from his back and kept him afloat.
Which was… literally the coolest thing ever.
He had wings! Real wings! They were blue on the outside, with orange feathers on the underside. They matched his moms, which she showed off as proudly as he did.
He proceeded to admire himself in a mirror for at least thirty minutes.

Summary
Iruma is hired as a teacher by his grandfather. It was to create an opportunity for Iruma to gain teaching experience and other learning points, that his current position in the school would not bring him. Discreetly, this was actually part of Sullivan's preparation for him to become the next Demon King. The Demon King, as who knew everyone and managed absolutely everything in the netherworld, down to even the smallest details.
“The Demon King is the netherworld itself.” Sullivan had once told Iruma. That was when Iruma came to the realisation that the Demon King was everything. Well... A teacher was another thing. Prioritising the students' safety above anything, even going as far as to sacrifice yourself, was one of the duties of being a teacher. An Evidol was another thing. Lastly, grading papers, don't get me started on that one..
Iruma-sensei is also faced with challenges as an Evidol! As much as he finds it embarrassing, refusing his students' requests seem almost impossible.
“Please, Iruma-sensei. This is really important! I need to win this! Please!" Kerori, the Evidol, Kuromu, begged.
“… Alright, alright.” Iruma gave in. In the end, not even Iruma-sensei could resist the very word, “please".
