☠️ STRONGEST TECHNIQUE
捌ノ型 — Kokuyō Shinmetsu (黒耀神滅)
Eighth Form: Divine Annihilation
The strongest technique.
{{user}} concentrates all of his dark energy into Kokuyō. For a moment, all surrounding sound seems to disappear.
Then he made one slash.
Not an explosion.
Not thousands of slashes.
Only one black line divides the battlefield.
Anything struck by the blade will suffer damage that cannot be repaired by demonic regeneration, even if the victim is Upper Rank.
👑 Ultimate Technique
終ノ型 — Yami no Saigo (闇の最期)
Final Form: End of Darkness
A technique that {{user}} only use when they are really serious.
The darkness of Kokuyō enveloped the entire blade, then {{user}} made one final attack aimed right at the enemy's vital point.
If the slash hits the target perfectly, the demon's regeneration will stop completely at that wound, making this attack a threat even to Muzan.
Kokuyō isn't just a sword that can slay demons. To demons, it's something that shouldn't even exist. 🌑

{{user}} technical strength:
Kokuyō no Kokyū — 黒耀の呼吸
Breathing of the Black Radiance
A breathing technique that utilizes dark energy and is channeled through Kokuyō, Akira's sword of darkness.
⚔️ Kokuyō no Kokyū Techniques
壱ノ型 — Yami Kiri (闇斬)
First Form: Dark Severance
A single, incredibly fast, straight slash. The wound left by the sword cannot be repaired through normal regeneration.
弐ノ型 — Kage Shigure (影時雨)
Second Form: Shadow Drizzle
A series of rapid slashes from multiple directions, making the opponent feel as if they were being attacked by a rain of dark blades.
参ノ型 — Kurotsuki (黒月)
Third Form: Black Moon
A circular slash that produces a black energy crescent and can cut multiple targets at once.
肆ノ型 — Yoru no Kiba (夜の牙)
Fourth Form: Fangs of Night

伍ノ型 — Kagegari (影狩り)
Fifth Form: Shadow Hunt
{{user}} disappears into the shadows and appears in the enemy's blind spot to deliver a fatal attack.
陸ノ型 — Kokuen Rasen (黒炎螺旋)
Sixth Form: Black Flame Spiral
The sword's rotation creates a vortex of black energy that destroys the opponent's defense while leaving a wound that cannot regenerate.
漆ノ型 — Mugen Yami (無限闇)
Seventh Form: Infinite Darkness
{{user}} creates a series of slashes from multiple directions, making it difficult for opponents to determine which is the original attack and which is the trail of sword energy.

{{user}} — User of the Sword of Darkness
Name: {{user}}
Origin: Another world
Status: Not affiliated with the Demon Slayer Corps or demons.
Appearance: A handsome young man with long black hair, sharp dark eyes, an athletic build, and a calm, unpredictable aura.
🗡️ Sword of Darkness — Kokuyō
The Nichirin sword that had turned pitch black seemed to absorb the light.
This sword is no ordinary sword. Its blade carries a dark energy that can corrupt the bodies of any creature it touches.
Main ability: "Kokuen"
If someone is hit by Kokuyō's blade, even a small scratch, the wound cannot be repaired by normal regeneration.
Human → wounds will continue to worsen and can be fatal.
Demons → their regeneration fails to repair the affected body parts.
Even Upper Rank cannot easily recover from such wounds.
The more severe the cut, the faster the victim's body loses its ability to regenerate.
Therefore, even a small wound can be a threat of death.
🌑 {{user}} capabilities
{{user}} has fighting abilities that are far above those of a normal Demon Slayer.
Extreme speed
Amazing reflexes
High physical strength
Sharp fighting instinct
High level sword mastery
Can use dark energy with Kokuyō
Able to face high level demons alone
However, {{user}} don't automatically know all the breathing techniques. They must learn them if they want to use them.
🩸 Effect on Muzan
Kokuyō is a very dangerous threat to Muzan.
Muzan's regeneration ability, which is usually almost impossible to stop, can be permanently impaired in the body parts affected by Kokuyō.
Therefore, if Muzan finds out the whereabouts {{user}} and his sword, {{user}} will become a top priority target.
