Summary
Denji scratched at his skin a bit too often. Aki noticed. What a drag. Like, seriously. What was he supposed to do when the guy he was staying with was aware that Denji was prone to doing ridiculously painful and dumb things?
(or: a conversation about food and hangnails.)

Summary
Aki shifted a bit, and even that looked like hell for him. “Will you be able to handle things around the house?”
Denji and Power froze in thought.
Cooking food, cleaning the house, taking care of Meowy, laundry, grocery shopping…
Denji threw on a smile and nodded. “Leave it to us. You just…make sure you’re rested up.”
Aki is injured after a mission goes wrong. While he is hospitalized, it's up to Power and Denji to make sure their home stays a home.

Summary
Aki had become accustomed to pressing away the harrowing thought of his future. He kept his cursed sword purposely tucked away from him at all times, it being the first thing he took off and nestled by the door of his bedroom as he undressed. He’d spent so long being unburdened by however many more years he had left that he didn’t think to check.
That is, until Denji. Denji with his stubborn tongue and his needy, scratchy whine ringing in Aki's ear.
He must've been out of his fucking mind to miss it, now.

Summary
The 17th never meant anything—until it did. Now, every year, it comes back like a bruise under Aki Hayakawa’s ribs. When he’s sent alone to investigate a disturbance in a forgotten park, something impossible stirs beneath the roots of a willow tree. Something that shouldn’t be there. Something that knows his name.
As the past resurfaces in a shape both familiar and wrong, Aki is forced to reckon with what lingers in the spaces between memory and mourning. To face the question he’s long avoided: how far would you go for someone you once loved, when what’s left of them might not be human anymore?

Summary
Aki and Himeno go on a mission. Like that’s all lol :)
The creature was now on the floor, torn with blood. Aki was searching it, but it had no gun chunks. (He kind of didn’t even want to touch it)
Still, it had actually ended up being a pretty hard fight, and it showed on the two coworkers, Himeno’s shirt bloody and torn lightly in places and pants scuffed and lightly ripped around the thighs, and Aki’s clothing showing the same effect.
“We should go, right? Gotta get back to HQ.”
Aki wanted to shower. That thing was so… eugh.

Summary
Aki never thought he’d find himself in the possession of a pup, especially one with so much baggage. And yet, he finds himself carrying one in a bundle of blankets, his scrawny form shaking.
“Is this okay?” He asks, met with a tiny nod as the boy settles against him, inhaling his scent and purring. It wasn’t what he had expected to come of his day, Denji was normal that morning. Now, he’s small in his arms, shivering at the cold. Some reversal devil, Makima explained to him. Exterminated safely, he should go back to normal sooner or later.
Or, Aki somehow ends up with even younger pup Denji on his hands, unprepared to be thrust back into the roll of an elder brother.
