Darkness. That's how it always ends. His body floated through the dark void, at least half of it. Even in death, he still couldn’t find peace. The man's wife, long-lost comrades, or mother were nowhere in sight.

It was a beautiful-starry night, but the man’s old heart was devastated when confronting his now-demon-turned brother. He shed tears and said his apologies, but the fact the brother he still loved had betrayed the demon slayer corps, he had a job to carry out. The man used all his strength and slashed at his brother's throat, but the demon sibling stumbling made the cut too shallow. Before he could strike again, his heart and breath slowed as darkness appeared at the edge of his vision. Old age had caught him, and the last thing he saw was the unrelenting hatred in his brother’s six eyes.

The faint sensation of steel passing through flesh didn’t faze the dying elder as his life faded and his soul arrived in the dark void.

The only thing the man felt was a deep sadness that plagued his lengthy life. The day his mother’s illness killed her. The day he found his soon-to-be wife and unborn child slaughtered in his own home. The day he failed to kill Muzan. The same day he found out his brother WILLINGLY turned himself into a demon. That sadness was always there in his mind, waiting for another opportunity to turn the calm and stoic man into a ruined mess of emotion.

But, the only thing his mind was focusing on was the hate-fueled glare his brother gave him. What had he done to deserve such a look? Ever since they both were small, the man loved his brother dearly no matter what, the wooden flute being a testament to that. Had he done something or said anything to anger his brother? Maybe it was his fault; he should have been better.

The man's self-loathing was interrupted when a bright light shined upon him, accompanied by a pulling sensation. He had to shut his non-existing eyes to block out the blinding light as a loud bang made his ears ring.

A gentle breeze blew over the man's body, which he’d found to be hairier than usual. He could feel his clothing cover most of his body, a body that didn’t feel right. Opening his maroon eyes, the man saw a densely packed forest shrouded in darkness, despite the sun that lit the clearing he’d laid in. With a silent sigh, he attempted to stand; but found himself falling back to the earth.

The man quickly caught himself mid-fall with a…hoof? Sure enough, right below him was a hoof with rosy red fur. Looking over himself, the clothes he wore were still on him but was shocked to see his human limbs had been transformed into legs resembling that of an equine. During his examination, the ma- stallion saw that his Nichirin sword was still on his side.

Deciding it was time to get out of this awkward position, the stallion carefully got on his newly received hoofs without much trouble. Pride sparked in his heart for a moment before dying down. Now taking his attention away from his horse body, the sinister forest sounds echoed around him as he listened for any sign of danger. Suddenly, the stallion felt the sensation of heavy blood lust coming from behind him. He turned around calmly as a growl came from the direction of the fearful sensation, as a strange beast emerged from the bush, almost making the stoic stallion raise an eyebrow in confusion.

It had the body and head of a Lion, the wings of a bat, and a tail appendage with a sharp end to it. The last part brings back memories of his and Muzan’s first encounter. The beast growled at him with hunger, getting in a low stance, ready to pounce the stallion when he dropped his guard.

The stallion wasn’t one to inflict harm on other living things without a reason. In his younger days, the stallion's brother's teacher taught him how to swing a wooden sword, and he wanted to test his progress. Due to his unique abilities and surprising strength, the teacher got knocked into the air in four strikes and knocked unconscious. Since that day, he vowed never to pick up a sword, the feeling of hurting a person was too painful for him. But in this instance, the stallion wasn’t above killing the beast to survive, much like the countless demons he’d slayed.

The beast roared as its powerful legs kicked off the ground toward the stallion. With ease, the stallion dodged out of the way. The beast crashed into the dirt as the stallion backed away, it quickly got back on its feet and tried a second time. The stallion went to grab his sword but found that he could not draw his blade due to the lack of hand. Barely dodging again, he put his mind to work on how to kill the beast, and a simple idea came to him. With a bit of dignity shriveling up in agony, he swiftly brought his mouth to the sword's handle and bit down on it. The beast charged again but howled in pain as a burning sensation came to its now cut-off leg.

A bright fire effect followed from the wound to the swordspony, leading to the sharp edge of a bright red sword held in the mouth by the stoic stallion. The beast fell to the ground again, crying in pain with barely any blood coming out of its cauterized wound.

“Sun breathing technique, first form: Dance.” The stallion muttered, barely understandable due to the weapon in his muzzle. He turned and faced the beast, standing with the hungry look still in its eye, now with a mix of anger and caution. The stallion hardened his gaze and ran at the beast. “Setting sun transformation.” The beast backed away as the flaming sword swung at him but yelped in surprise and pain as the sword somehow slashed it without reaching.

Blood sprayed from the beast's neck as its eyes rolled back, falling to the floor with a thud. The stallion lightly landed on the ground behind the lain beast and exhaled, steam trailing from the corners of his muzzle. Sheathing his sword, he picked a random direction and started to trot off into the darkness.

On that day, the Everfree forest was a bit brighter.

"Your majesssty, we have brought the prisssoner." The Changeling said as it and its partner dragged a relatively large stallion in front of the changeling queen herself.

The stallion had white fur, a long wild black main, and a cutie mark of 3 claw slashes. His eyelids fluttered before slowly opening to reveal a pair of cat-like red eyes that weakly glared at the insect monarch before him. “W-What is this vile place?” He mumbled. Looking around, it was a vast chasm with walls covered in a green and black slimy-looking texture. Holes carved into the chasm surface only led to darkness as bug-like horses crawled out of them.

“Stand before your true queen, pony scum!” The changeling queen loudly commanded. She growled in irritation when the pony didn’t comply and smirked as her horn glowed a sickly green. An aura of the same color surrounded the exhausted stallion and violently pulled him until he was inches away from the queen's glaring face. “NOW, STAND!” The stallion was violently thrown to the ground, his forelegs almost breaking under the force.

Despite the rough wake-up call, the stallion stood tall with a minor sway. The queen grinned pridefully as she laid back on her throne. “What’s the name of the pony scum I’m about to wipe out?” She sarcastically asked, not caring if he’d answer or not.

The stallion looked up at the queen with a cold glare and a ghost of a smirk.

“Muzan Kibutsuji”
