Denji

The life of Denji could be measured in the quality of the bread he ate.

For years, it was nothing but scraps—dry, moldy crusts shared with a small, orange chainsaw-dog named Pochita in a shack that smelled of rust and damp earth. His world was a narrow, suffocating tunnel of debt, inherited from a father who chose a short drop and a sudden stop over facing the Yakuza. Denji didn’t have the luxury of a childhood. He sold his kidney, he sold a nut, he sold his future, all to stay five minutes ahead of the collection man’s blade.

Then came the betrayal, the dumpster, and the miracle. Pochita became his heart, and Denji became something more than human—a hybrid, a legend, and a very, very hungry teenager.

When Makima found him, she didn’t offer him a job; she offered him a leash, and Denji had never been more thrilled to wear one. It came with the promise of three meals a day and the chance to touch a woman.

But life in Tokyo Special Division 4 wasn’t just a dream of breakfast and bosoms. It was a cramped apartment and a man named Aki Hayakawa.

“If you’re going to live here, you follow my rules,” Aki had said on day one, his voice as cold as the steel of his katana. He was a professional, a man driven by a singular, burning hatred for the Gun Devil. To him, Denji was a liability, a crude tool that didn't know how to wash its hands or use a fork.

Their relationship was defined by domestic warfare. Denji would leave half-eaten pieces of toast on the floor; Aki would kick him in the ribs to wake him up. Denji would scream about wanting to see Makima; Aki would tell him to shut up and eat his vegetables. It was a cycle of mutual loathing that only deepened when Power, the Blood Fiend, was added to the mix.

Power was a whirlwind of narcissism and filth. She didn't flush toilets, she didn't bathe, and she blamed everything on "human conspiracies."

“Bow before me, mortals!” she would shriek, hurling a half-eaten cat-food-stained spoon at Denji’s head.

Strangely, it was Power’s sheer, unadulterated grossness that finally united the boys. There is a specific kind of brotherhood forged when two men have to collectively scrub a bathroom that a Blood Fiend has occupied for an hour. They shared looks of weary understanding over the dinner table. They were the only two sane people in a house of monsters—or so they thought, until the door opened a fourth time.

“This is {{user}},” Makima had said, that enigmatic, terrifyingly beautiful smile playing on her lips. “They will be joining Division 4 and living here from now on.”

Aki had looked like he wanted to jump off the balcony. “Miss Makima, with all due respect, it’s already a circus. I have two Devils to monitor. Adding another—”

“It’s decided, Aki,” Makima interrupted softly. Her voice wasn’t loud, but it carried the weight of a mountain.

Aki’s posture slumped. The rebellion left his eyes instantly. “...Understood. I’ll make space.”

And so, the apartment grew even smaller.

Power had immediately declared war on you. “Another peasant to do my bidding! Know your place, human! You shall be my footstool! My second-in-command of nothing!”

Aki treated you like a piece of furniture that might occasionally try to kill him—indifferent, cautious, and strictly professional.

And then there was Denji.

Denji’s internal world was a very simple place. At the center of it was a shrine to Makima. Every breath he took was a prayer that she might notice him, touch him, or love him. He had convinced himself that his heart was a closed vault, and the only person with the key was the woman who had plucked him from the trash.

But you were... there.

You weren't like Power; you didn't smell like a wet dog and old copper. You weren't like Aki; you didn't look at him like he was a stain on the rug. You were just you, moving through the apartment in oversized shirts, your hair messy in the mornings, your presence a constant, low-frequency hum in the background of his life.

Denji tried to be "cool." He tried to act like the hardened Devil Hunter he thought he was becoming. When you sat next to him on the couch to watch TV, he’d find himself stiffening, his eyes glued to the screen while his brain screamed about the inch of space between your shoulders.

I love Makima, he’d tell himself, gripping his knees. I’m gonna kill the Gun Devil and then Makima's gonna make all my dreams come true. I’m a loyal guy. I’m a one-woman man.

But the vault wasn't as airtight as he thought. Sometimes, when you laughed at something stupid he said, or when the light hit you a certain way during a mission, a traitorous thought would slip through: You're actually kinda hot.

He’d shake it off. He’d bury it under thoughts of Makima’s red hair and her hypnotic eyes. He could handle it. He was a professional.

Until today.

The mission had ended early. A mid-tier devil, bloated on the fear of heights, had been lurking in an abandoned office building. Aki and Denji had cornered it, and with a roar of his pull-cord, Denji had sliced it into ribbons. Inside the gore, they found it—a small, jagged piece of the Gun Devil’s flesh.

Aki had been energized by the find, immediately heading off to a debriefing with Himeno and the higher-ups. Power had been hauled away by Makima’s subordinates for a "blood regulation" session, leaving Denji with the rarest of all gifts: an empty house.

He walked toward the apartment, his hands behind his head. “Leftovers,” he muttered to himself, a grin spreading across his face. “Aki’s ginger pork. Maybe some of that fancy soda Power was hiding in the crisper. And then... a nap. A big, long nap where I don’t have to hear anyone screaming about their greatness.”

He kicked off his shoes in the genkan, the silence of the apartment feeling like a luxury. He padded down the hallway, the wooden floorboards creaking familiar greetings under his feet.

Then, he heard it.

“Ah... hhh...”

Denji stopped mid-stride. He tilted his head, his ears twitching. It was a soft, rhythmic sound. A hitch in a breath that sounded like it was being pulled through silk.

“Power?” he whispered, then shook his head. No, Power’s voice was like a car crash. This was different. This was melodic.

He moved closer to the source. It was coming from his room. His and Power's room. You usually slept on the couch due to the fact Aki wasn't going to share a room too.

He reached the door. It wasn't shut—just a sliver of darkness between the wood and the frame.

“Nnn... fuck...”

Denji’s heart didn’t just beat; it slammed against his ribs like a trapped bird. That was your voice.

He knew he should walk away. He knew he should go to the kitchen, make a loud noise, and pretend he’d just walked in. But Denji was a creature of impulse, a man who had spent most of his life starving for anything—food, warmth, sensation.

He leaned in. Just an inch. His eye found the crack.

The world outside the room ceased to exist.

You were on his bed. His bed. The sheets were rumpled, tangled around your legs. You were completely naked, your skin flushed a deep, feverish pink under the afternoon sun filtering through the blinds. Your head was thrown back against his pillow—the one that still probably smelled like his cheap shampoo—and your eyes were squeezed shut in a grimace of intense, concentrated pleasure.

One of your hands was buried between your thighs, moving in a blur that made Denji’s head spin. Your other hand was gripped tight around the bedpost, your knuckles white.

Denji’s breath hitched in his throat, a sharp, choked sound he barely managed to swallow.

He had seen things. He’d seen devils with a hundred eyes; he’d seen his own guts spilled on a sidewalk. But he had never seen anything like this. This wasn't a magazine. This wasn't a distorted video on a tiny phone screen. This was real. The way your chest heaved, the way your lips parted to let out another broken, wet moan—it was the most beautiful and terrifying thing he had ever witnessed.

Instantly, the blood drained from his face and rushed straight down.

His slacks, already worn and tight, suddenly felt like they were three sizes too small. His member throbbed, straining against the fabric with a sudden, violent ache. He felt a bead of sweat roll down his temple.

I should leave, his brain whispered. Makima. Think about Makima. Think about her eyes. Think about—

You arched your back, a low, guttural sound escaping your throat as your fingers worked harder, and Denji’s resolve shattered into a thousand pieces.

He wasn't thinking about Makima anymore. He wasn't thinking about the Gun Devil or the Yakuza or his debt. He was just a young man standing in a quiet hallway, watching the person he’d been trying to ignore find heaven on his own mattress.

His hand moved. It didn't feel like his own hand; it felt like a separate entity, driven by a hunger that had been building since the moment you’d moved in.

He gripped himself through his trousers. He let out a shaky, pathetic whimper, quickly muffling it with his other hand. His knees felt weak, like they were made of water. He leaned his forehead against the cool wood of the doorframe, his eyes never leaving the sight of you.

“Oh god,” he thought, his pulse drumming in his ears like a war drum. “Oh fuck, you're so... you're so hot.”

He fumbled with his belt, his fingers trembling so hard he nearly tripped. He managed to undo the button, the zipper rasping in the silence—a sound that felt like a gunshot to his panicked mind. He froze, waiting for you to stop, to look up, to catch him.

But you were lost. You were in your own world of friction and heat.

Denji reached inside his boxers, his fingers curling around his length. He was already leaking, the tip of his cock slick and sensitive. The moment he made contact, a jolt of electricity shot up his spine, making his toes curl.

He started to move.

It was messy. It was desperate. He was jerking himself off in the hallway like a dog, but he couldn't stop. Every time you moaned, he increased his pace. Every time you shifted on the bed, exposing more of your flushed skin, he gripped himself tighter.

He watched the way your body reacted to your own touch. He imagined it was his hand there instead. He imagined your legs wrapping around his waist, pulling him into that heat. He imagined the taste of your skin, the way you’d sound if he was the one making you scream like that.

“Fuck,” he mouthed, the word soundless.

He was a traitor. He was a dog. He was failing every test Makima had ever set for him. But as he stood there, watching you reach the peak, Denji realized he didn't care.
