Summary
" [...] It had simply happened. Gaap had reduced the number of times he spoke to Agares, dragged him into class discussions, or helped him stay awake. Agares, for his part, no longer initiated conversations with Gaap, no longer flew away from the din seeking silence to sleep in peace, no longer scolded him or called him to him. He simply pulled his sleep mask over his eyes, excluding himself from the Misfits' conversations, but also from that part of the Netherworld where Gaap still had a place. A place that, apparently, was no longer by his side"
Basically Gaap and Agares loosen their friendship because they discover that they are in love with each other but do not know that the other reciprocates.

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.
(Previously "Like a Moth to Flame")

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
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)
