Summary
Survival only came for one thing.
He still may or may not feel guilty about the look on the other one's face when he suddenly yanked the human from the driver's seat and threw him into the back of their subconscious to usurp control but he did what he thought was necessary. This 'deviculum' was a disaster just waiting to happen. Like a ticking time bomb wrapped in a bow.
He knows who's attending and he knows Fenrir isn't who he says he is, but he doesn't care, what he's focused on is that Baal is here and Kirio is lurking in the shadows waiting to strike.
It's too bad really.
Because he'll strike first.

Summary
Humans are disgusting
Except for the other one, never the other one. The other one was too pure and kind for such a dirty world filled to the brim with such pathetic, worthless repulsive creatures such as human beings. They were selfish, greedy, backstabbing, scheming, and only cared about themselves and their money.
And there were no better examples than the other one's biological parents, they sold him off to a demon just for money but for some reason, he still kind of cared about them.
Because of that Survival couldn't put them into the ground.
This time, however, is different.

Summary
His survival instincts were peaceful.
Not harmless, peaceful. Much like a wild animal, Iruma's survival instincts were docile unless provoked, if you didn't approach him, he wouldn't approach you, it was as simple as that. Due to this his survival instincts were mostly docile, most of the time just running or dodging attacks, and would only kill if necessary.
But his survival instincts were peaceful, not harmless, and when provoked, he could deal out a some real damage, not as bad as a mauling from predator, but still pretty bad.
Unfortunately for Atori, he learned that lesson.
And he learned it the hard way.

Summary
The first birthday Iruma celebrated, was his fifteenth.
All the other fourteen years worth of birthdays were left uncelebrated, forgotten as Iruma continued to slave away at whatever shady black company his parents had coerced him to work at as his efforts were left unawarded and even his hard-earned salary was taken away from him.
Birthdays were something he's never had the freedom to experience, not with his parents, they were just days to acknowledge that he had gotten a year older.
Not in the Netherworld though, never in the Netherworld.
The Netherworld is much warmer and much more like home after all.

Summary
Iruma had mostly adapted to the Netherworld language
He had gotten a lot better had pronouncing the considerably harder words as well as writing and spelling some words the he had particular trouble with which boosted his language ability by a lot. Speaking was no problem for him as his grandpa had long cast a spell on him so he could understand what was being spoken.
But sometimes he missed the homely feeling of the Japanese language, it was his home country after all. He missed the way it would just roll off his tongue fluently and how he could write the characters like it was in his blood.
So sometimes after school in the privacy of his bedroom, he would speak Japanese to himself to rekindle nostalgic memories.
There was no harm in doing it, right?
(aka: The one where Iruma speaks Japanese in the Netherworld and confuses evreyone.)Series

Summary
For all the fans who are hungry for feral Iruma content, breakfast has been served.
Enjoy, because this is all crack taken seriously and it's all about feral behavior, animal instincts, predatory instincts, ripping animal's throats out, attempting to murder anybody who triggers your predator instincts, getting the blood of animals and demons alike splattered on your face and nails, and traumatizing adults!
Seriously, never ever trigger the instincts of a kid who has been forced to live in a jungle full of merciless predators from day one because that is never a good idea. Never underestimate a feral jungle child's unhingedness because you will live to regret it.
Now eat up.

Summary
Yin Yu is a promising cultivator with a talent for fortunetelling. He has a bright future, and he sets his sights firmly on ascension. It's in his star chart, after all.
What the stars failed to tell him was that Quan Yizhen would come in and steal his shizun, steal his place in the heavens, and steal his sight.

Summary
“You should’ve let me die.”
It’s the only thing Rocks has said, since he woke up last out of the three of them in the Oro’s infirmary. Which of course caused Roger to insist “Like hell-” at the same time Garp snapped “Don’t be stupid!”

Summary
Roger isn’t sure what he’s seeing, not at first. Bunch of dead marines, yeah, okay, made sense for an island that’s turned into an active warzone. Garp kneeling down in the middle of them? Crying? Didn’t make any damn sense.
It isn’t until he’s taken a few steps forward that Roger clocks how young these particular dead marines look, and then a bad feeling sets up shop in his gut.
