Kyo

Kyo is an original character and is a supporting antagonist in Final Sunrise. She is a demon affiliated with The Twelve Kizuki, holding the highest position, Upper Rank One

## Appearance

Kyo takes the appearance of an elegant and beautiful woman. Kyo is a tall and slender female with pale skin. She has long black hair tied to make it less messy. She wears a variety of black and white dresses, suits and kimonos, and wears a deep purple Amethyst necklace on her neck. In her eyes, the kanji for "Upper Rank"  and the daiji for "One" are etched into her irises, but with her eyes being as black as a black hole, they are not visible in the slightest.

## Personality

Kyo is what you would call a very unique type of demon. She has shown to have a large quantity of determination and will power, it goes so far to the point where she just doesn't know when to give up on her goals. And has shown respect to those who also have a strong will, no matter their ranking in power. This determination of hers is mostly on display when in combat. Pushing away from her determination, Kyo is split into two categories in terms of personality. Either she is the most intimidating and serious person you will ever meet, or the most energetic and eccentric one. That's where her uniqueness comes in.

Kyos more friendly side is mostly shown around the elders and kizuki, where she is rather kind and surprisingly very full of energy. While that's without saying it's also true in combat, it's also not what you would expect from the Upper Moon 1 herself. However, Kyo can definitely be more serious and cold, especially towards those who show disrespect within the Kizuki ranks. Its a rather complicated way of acting, as you can never know how Kyo will ever be around certain people or “comrades”. The only individual she is rather collected and reserved around is the Queen of Demons, Kyo having respect for the queen yet also fears them deeply.

Around slayers, she has no problem simply torturing them to death if she so pleases, but mostly decides to kill them swiftly and with no pain. However that's to say Kyo does not normally kill humans like a beast hunting for sport, she can engage in conversations and really likes talking to non-slayers or very VERY low ranked ones. And while she is not battle-crazed, she does like a good battle, and is willing to admit when someone is a skilled fighter, even praising them for their skill.

## Abilities

Overall Abilities: As the holder of the highest position in the Twelve Kizuki, Kyo is an extremely powerful demon, being only surpassed by the Queen herself and Gozu, while being on the equal side of things of a few Elder Siblings. Her extremely powerful Blood Demon Art and techniques allow her to easily outclass “all” demons and give her the necessary edge to completely overpower and kill even (Marked) Hashiras, the most skilled and powerful swordsman in the Demon Slayer Corps.

Flesh Manipulation: Like all demons, Kyo possesses the ability to manipulate her own flesh. Though it doesn't seem as if she uses it often.

IImmense Durability: As the highest Upper Rank demon, Kyo possesses an extremely durable body superior to that of average demons and Upper Demon 2. Her flesh is so tough that even Marked Hashira has trouble breaching through the outer layer. Notably her neck and arms are much more durable and tougher than the rest of her body being more difficult to cut off.

Immense Regeneration: As the highest Upper Rank demon, Kyo has very powerful regeneration. Being able to regenerate instantaneously after being slashed by a Nichirin Blade. Even with the usage of the Red Blade, her regeneration is still surprisingly extremely fast.

Immense Speed & Reflexes: Kyo is an incredibly fast opponent. Being able to easily evade Hashiras attacks that have successfully awakened their Slayer Marks, meaning that their speed would have amplified considerably. Kyo is able to move so fast that she appears to teleport to even the second highest ranked Upper Kizuki.

Unlimited Stamina & Endurance: Like all demons, Kyo possesses infinite stamina and endurance. As she does not show any signs of pain even if receiving slash wounds or being attacked by a Marked Hashira or other Kizukis.

Immense Strength: As the highest Upper Rank demon, Sumire has shown to be incredibly strong in physical power. As she usually engages into combat with her own fists. Her strength being able to easily destroy the toughest of steel and smash giant boulders with a kick.

Extrasensory Perception: Kyo possesses extraordinary sensory abilities which allow her to detect things outside the normal range of perception, allowing her to nullify the effectiveness of sneak attacks. It's so powerful that she has even turned this into a weapon, using it to detect attacks from hostiles, making this a “Danger Sense”.

Indomitable Will: Kyo possesses an immense willpower and undaunted spirit.

Tactical Intellect: With over centuries of combat experience, Kyo is able to fight effectively with foresight and tactical intelligence. It goes beyond the point that she can predict when her opponents will strike and how to counter them alongside her Danger Sense.

## Fighting Style

Umbrakinesis: Kyos Blood Demon Art grants her the powerful ability of Umbrakinesis. She can generate darkness and can spawn it anywhere in her vicinity, as well as manipulating it at will, allowing for some incredibly powerful and potent techniques.

This is what grants Kyo her nickname as “The Void Demon”, as it's said that she can even manipulate the purest of black things in the Universe. Black Holes. Now it's all a figurative of speech, but she has shown the ability to generate pure darkness.

## History

With how long Kyo has lived, her history has almost been lost completely, but it is still there.

During her life as a human, when she was named Yamamoto Mitsuki rather than Kyo, was raised in an ancient but small village with her loving parents and siblings, having a pretty great and normal childhood. As a young woman, she was seen as the jewel of the village, being known for her ominous beauty and courage. She had also been taught how to fight, having turned into a skilled fighter, having been trained in various martial arts. But nothing could stay the same, as one night while she was traveling with a group to a cave, it had been getting late so the group decided to call it quits with whatever they were searching for and go back home, it had turned into a blood-bath as a group of thugs in equal numbers had suddenly attacked them during their way back to the village, Mitsukis safety being priority, she was quickly defended and was given time to escape.

But the moment she saw blood being shed to her group, it was like her whole body stopped, forcing her to watch, it wasn't about her own safety anymore, it was about her people's safety. What would happen if she returned just for the thugs to have somehow followed and invade with even larger numbers…Kyo as a human was too selfless, as not even a second was given to her thoughts and actions as the woman rushed towards the trained thugs, not as the jewel of the village, but as the skilled fighter she was.

She struck fear into the thugs, her mind wasn't in the right place, it could only think about avenging her fallen comrades. She showed no mercy against them, her adrenaline putting all her pain aside from using way too much strength then her own body could handle, like she had achieved 100% of her strength with how furious she was. The thugs laid dead on the floor alongside her people, having gotten killed by the girl's bare hands as she simply stood there on top of their bodies as blood covered her beautiful face and outfit. The night had become silent as she simply stared at the ground, knowing very well what she had done, but before she could return back home with the bodies of her fallen, a strange woman had begun to approach her, an ominous aura could be sensed from this woman that Mitsuki caught notice of.

With that sole reason, Mitsuki had assumed this was perhaps the leader of these thugs having come to kill her. Slowly approaching the woman as she got ready to attack, slowly clenching her fist before punching the woman in the face…to her surprise this punch didn't faze the woman, in fact not a single injury could be seen, no, they just didn't have an injury at all. Her bloodlust being rather high still, the girl continued to punch the woman despite no injuries being inflicted in the slightest. It was laughable…she couldn't even hurt the person she had assumed was the leader of the thugs who killed her group…but her fists were stopped, as she flinched at the sight at the woman resting their hand on her head before she simply heard the words

“It's going to be ok. I'm not here to hurt you child.”

At that moment, Mitsukis bloodlust had left her body entirely, it had hit that this wasn't the leader nor someone that was here to kill her…the stranger kept comforting her like they were her mother, as the slow realization that what she had done wouldn't reverse anything that had happened to her people, and as the adrenaline left her body, the pain of the injuries she had received during the battle would start to kick in even if she couldn't even express the pain she was feeling with expressions anymore, starting to fall unconscious…this was really how she would die…huh? But suddenly, the stranger offered them an opportunity, she could barely hear them anymore…but what she did hear were the words demon...she accepted the offer their new Queen made.

At first, she was struck with disaster, terrified with her own new identity even if this was what she technically wanted, and she knew this well. Regardless, just like any person, she was afraid and shocked about her new demonic appearance and power which was granted to her. As time passed, Kyo grew to embrace her new identity and power she was gifted. She survived through the harsh beginning that every demon starts, it was painful and rough trying to survive against the enemies also known as slayers, but she kept pushing forward no matter her challenges, becoming stronger and developing her blood demon art.

As she grew more and more confident over the years, eating more humans and gaining more power. It felt like she was one out of the millions of “regular” demons that had been created from the Queen, as Kyo would rise through the ranks of demon society, becoming a member of the Kizuki Demons as the Upper Moon 1.

There is so much left to explore in her history, like what she did in the war, her long living bloodline which still remains alive to this day. However, maybe that's something to discover later on? Whatcha think?
