Infinity castle arc: part one

**Infinity Castle Arc: Kutsuki Sabiha’s Stand**

The Infinity Castle’s shifting corridors had already claimed many lives by the time Sabiha landed. The wooden floors twisted beneath her feet like living serpents, disorienting her sense of direction. She moved with the patient, measured steps of someone who understood decay—rushing would only hasten her own end. Her rust-orange haori fluttered behind her, the fabric stained with the dust of earlier battles.

A familiar scent of wisteria and blood cut through the air. She rounded a collapsing hallway and nearly collided with **Tsuyuri Kanao**, who was sprinting forward with her Nichirin blade drawn, eyes wide with rare, burning determination.

“Kanao!” Sabiha called, voice steady despite the chaos. Kanao glanced back, surprised, but nodded sharply. No words were wasted. The two young women fell into step—Kanao’s precise, flower-like movements complementing Sabiha’s slower, grinding attrition style. They raced toward the overwhelming aura of Upper Rank Two.

They burst into Doma’s frozen domain just as the horror unfolded.

Shinobu Kocho’s broken body was disappearing into the demon’s gaping maw, her final defiant smile still etched on her face as the poison coursed through him. Doma laughed brightly, blood and wisteria toxin dripping from his lips. “Ahhh~ What a shame! She tasted so bitter-sweet!”

Kanao’s breathing hitched. “Shinobu-sama…!”

Sabiha’s grip tightened on her Nichirin katana. The sight of the Insect Hashira—someone who had shown her quiet kindness during training—being consumed ignited something cold and furious in her chest. “We end him here,” she said quietly. “Before he digests her poison… or her.”

The battle erupted.

Kanao moved first, her **Flower Breathing** a whirlwind of graceful, lethal strikes. Sabiha followed with heavier, deliberate forms, her blade trailing reddish-brown particles that clung to Doma’s regenerating flesh like acid.

**Third Form: Flaking Barrage** — Sabiha spun into a storm of slashes, scattering rust flakes across Doma’s arms and torso. The particles hissed and smoked as they ate into his icy skin, slowing his regeneration just enough for Kanao to land deeper cuts.

Doma giggled, unfazed. “Ooh, a new toy! Your rust is so pretty~” He unleashed a barrage of ice lotuses and fan strikes, forcing them to dodge across the frozen platforms.

They fought in sync: Kanao’s speed creating openings, Sabiha’s corrosion wearing him down. Sabiha switched to **Fourth Form: Galvanic Decay**, spinning her blade in a defensive vortex of oxidizing particles that corroded Doma’s incoming ice constructs mid-air, turning them brittle and shattered.

But Doma was Upper Rank Two for a reason.

In a blindingly fast motion, he closed the distance. His fan, edged with razor-sharp ice, whipped across Sabiha’s face. She barely turned her head in time—**the fan sliced deep across her right eye**.

Pain exploded. Blood poured down her cheek, hot and stinging. Her vision in that eye went dark, replaced by a burning haze. She staggered, clutching her face as rust-colored blood mixed with her tears.

“Sabiha-san!” Kanao cried, covering for her with a desperate **Flower Breathing**.

Doma tilted his head, smiling serenely. “Does it hurt? Good. Let’s make it match your pretty rust theme~”

Something inside Sabiha snapped—not rage, but the cold, inevitable truth of decay. *Everything breaks down. Even demons.* Her breathing deepened. The pain in her ruined eye pulsed in time with her heartbeat.

Then, the **Demon Slayer Mark** awakened.

Jagged branches of rust under her left eye.

**Sixth Form: Structural Collapse** — Empowered by the Mark, Sabiha lunged. Her blade moved with terrifying weight, superheated by concentrated oxidation. The slash connected with Doma’s side, carving through his flesh as if his immortal body were crumbling rusted iron. Chunks of his torso flaked away, regeneration visibly struggling against the mark-enhanced corrosion.

Kanao, seeing the opening, pressed the attack with renewed ferocity, her eyes filled with tears and resolve.

Together they drove Doma back across the frozen hall, buying precious time. Sabiha’s voice was low and steady even through the agony in her eye: “You consume everything… but everything returns to rust in the end.”

Doma’s smile faltered for the first time, his body smoking from the combined poison and rust corrosion. He laughed again, but it sounded strained. “How interesting…! But I’m still not done playing~”

The fight raged on, the two Slayers standing together against the demon—Sabiha’s newly awakened Mark burning bright, her right eye a bloody ruin, yet her will unbreaking.

Haganes nightmares

(These nightmares take place after the events of Blood-Stained Money)

Hagane hadn’t slept for days at this point.

Every time he thought about taking a break, the voice would speak.

Hagane: “I… am tired… I need—”

Voice: “You need to continue.”

Hagane: “I can’t… I—”

Voice: “Yes, you can. This is your duty. Your responsibility. You survived, so every life left to save is now your burden.”

Hagane: “…”

Voice: “Or you can go back to your nice, soft bed in your warm house while people, children continue to suffer. Go on. Let them die.”

Hagane: “…I still can.”

Voice: “Your unholy crusade isn’t over yet. Destroy every single weapon. Hunt down every person responsible… or they’ll end up just like me.”

Hagane silently accepted another mission.
He never looked toward the source of the voice.
Because every time he did…

It looked exactly like.

>![redacted]!<

>!(Don’t expect a happy ending. As long as there is blood, there can never be a happy ending.)!<

My OC, Ruku Seiryoku, the Energy Hashira

A lot of Ruku's story wasn't written and mostly exists in my head so I'll try to recollect his story the best I can.

From the moment he could walk and hold a blade, his father trained him the ways of the demon slayers. When Ruku was 14, his father gifted him his own nichirin blade that was forged with superior steel from Europe. Ruku was to use it for the final selection. The following week after he returned, his father was nowhere to be seen but his clothes and sword, as if his body had disappeared. A fight seemed to happen in their house.

Demons of Bohemia Arc: Years later, he received his first mission as Hashira following his amazing feat of slaying over 50 demons in 1 night. He was to go to Europe to investigate claims of demons. When he arrived there, the rumors were proven to be true when he came face to face with a Werewolf and a Vampire. He successfully defeated both of them, but received grave injuries. He recovered a week later with the doctors surprised about his extremely fast recovery period, saying that most people would have died in his situation.

Emperor of Hell Arc: 1 year after the defeat of Muzan, Ruku had lost purpose. He was born to destroy demons, but there are none to fight. He only had a year left before the curse of the demon slayer mark would take his life. He taught people the way of the blade, but it was not enough to quench his thirst for battle. That was until he heard of rumors that a demon yet lives. He went to Tokyo only to learn that the emperor of Japan is a demon, a very powerful one at that. Ruku attempted to kill the emperor, only for him to send Ruku into his own pocket realm, a hellish landscape where the sun never rises, full of hungry demons looking for their next meal. He must get out of there before the demon slayer mark takes him first.

To clarify, this is my art. My reddit username outdated so it doesn't match my watermark.

Rust breathing demonstration + infinity castle illustration

1_First Form: Surface Corrosion

A quick horizontal slash that coats a wide area of the demon's body in rust particles, weakening regeneration in that zone for several seconds and making follow-up cuts more effective.

2_Second Form: Pitting Strike

Thrusting stab that creates small explosive bursts of rust along the entry point, digging deep "pits" into muscle and bone, disrupting movement.

3_Third Form: Flaking Barrage

Rapid multi-directional slashes that scatter rust flakes like a storm of razor-sharp metal dust. Great for crowd control against weaker demons.

4_Fourth Form: Galvanic Decay

A defensive spinning maneuver that creates a swirling barrier of oxidizing particles. Any demon limb or attack that passes through it begins corroding instantly, slowing and weakening the limb.

5_Fifth Form: Red Rust Cascade

Overhead downward slash that releases a waterfall-like cascade of heavy rust particles, weighing down and corroding everything in a narrow forward cone — excellent for pinning fast demons.

6_Sixth Form: Structural Collapse

A single, extremely powerful vertical cut aimed at the neck. The blade "rusts through" defenses by superheating the edge with friction and oxidation, making it feel like the demon's neck is crumbling apart even before the blade fully severs it.

7_Seventh Form: Eternal Patina (Personal ultimate form)

The user channels everything into one long, sweeping circular slash that envelops themselves and the target in a dome of thick rust mist. Inside, regeneration is almost completely halted while the user's blade gains extreme cutting power from concentrated oxidation heat. It ends with a final thrust that aims to sever the head while the demon is too decayed to resist. (High stamina cost — usually a last resort.)
