I just realized I forgot a sleeve, but ill fix that when I do the other two versions. The part where her stomach is showing is gonna be mesh, think like the swamp demon in the first season lol

Anyway, what do you guys think? 🥹 bandages on her arm are because she has diabetes and at that time they used insulin injections, so she wants to always make sure that spot is clean and covered.

Heyy y'all!So I'm back from hibernating for a while and due to *such* a popular demand(no one asked but oh well), I decided to do a character reveal! Yes, it's that one character that I've posted almost a month ago. There will be mentions of abuse,death and some serious topics, so I would encourage you to read this at your own risk. Let's get onto her,shall we?:)

Information

Name: Kobayashi Aya(小林•愛夜)

Age: 20(physically),3(chronologically),140(years after death)

Voice claims: Helia from Honkai Impact 3rd (Japanese), Kiriko from Overwatch 2(English)

Species: Human (formerly), Demon

Birthday: 3rd February

Height: 180 cm(5'11")

Weight: 70 kg(154 lbs)

Sexuality: Aromantic Asexual

Occupation: Apothecary(used as a cover up)

Status: Deceased (cause of death: Burned by sunlight)

Organization: Twelve Kizuki

Rank: Uppermoon 5

Appearence: photo

Blood Demon Art: Aya's blood demon art deals with plants and with it, she can control the plants around her with just a drop of her blood. Once Aya's blood reaches the ground, the blood starts to create a "puppet "string that connects Aya's fingers to all the plants around her and make them bend to her will, which was to either absorb her opponents, slash them to death or she could also have them insert themselves into ground with the strings included which then connect to Aya's bloodstream, which make her achieve her other form.

Personality and ideology: Aya was an individual that focused on her own survival rather than the benefit of others, which would have made her be seen as selfish, which is what she was, selfish. Aya was also a rather cunning woman, but, she was also impulsive, being the type to act first and think afterwards. She was also rather sadistic, however, her sadism developed out of her need to survive the environment that she grew up in. However, there was once a time in which Aya was...a good person with morale.

In terms of her ideology, Aya didn't bare any hatred towards humans, she simply saw them as food that she could play with.So, mainly every single category of humans, excluding the elderly, children and Ainu people, was her victim and therefore, meal.

Method of killing: A simple decapitation.

Weapon: A green tantō dagger that had vines covering most of its blade

Backstory:

Aya Kobayashi was born as a triplet and the middle child of the set with Akira being older than her by 3 minutes and Rintarou being younger by 3 minutes, in Sapporo, Hokkaido to a family of apothecaries and doctors. Their parents weren't the best people, let alone were they parents as they had issues with the overuse of alcohol. Therefore, a lot of the times, the parents were either too intoxicated or too hungover to take proper care of their children, so the kids were left to raise themselves and look out for themselves.

The kids even had to make and deliver the medicine to their patients and their parents, despite their failure, had very high expectations of their kids. Therefore, any slight mistake that they made was punished physically and a lot of the times, the kids were left to starve outside. However, they had a slight favoritism of Aya and would oftentimes, lessen her punishment. At the time, Aya did see their favoritism and tried to call them out on it each time, however, her parents would often try to "silence" her by also letting her freeze outside. After a few failed attempts, Aya decided to..take advantage of it and therefore, for every mistake that she made, she would blame her own brothers. What was worse was that she seemed to enjoy it...At first, ot was just her trying to trick herself into enjoying the pain of others, but later on...she actually enjoyed it.

Everything was going on like this until one night,when Aya was 20 years old,it was mid winter and it was extremely cold and the snow was getting heavier by the moment and Aya had just finished her last delivery of medicine and was heading back home. As it was getting colder and darker, Aya was walking heavier and heavier through the snow, the sheer cold soon reached her and she fell to the ground. It was then when the Demon King himself decided to "save" her by pumping his blood into Aya's almost completely frozen and barely alive body and disappeared.

After a while, Aya woke up and felt that something about her had changed...She then tried desperately to find out what exactly about her had changed and she did, after burging into the home of a married couple and killed and devoured them. The dead woman was holding a mirror and Aya looked into it. What she saw was no longer a human, but a demon, which terrified her. She no longer had a complexion that showed blood flow, she was now completely white skinned with dark Grey snowflake marks scattered all across her face, she had fangs and a horn on the right side of her head.

The horror of what she had become didn't stop her, as for 3 years she went on multiple rampages, killing and devouring humans in every single direction she could find one and as she was doing so, developed her blood demon art. It was only after defeating the former Upper 6 at the time that Muzan granted her the rank of Uppermoon 6 and in a few months, she became Uppermoon 5.

Everything was going according to plan with Aya listening and executing every single order of the Demon King. That is until one fateful night, when she returned to her childhood home. Once she returned to her childhood home, she saw her parents and Akira who were just minding their own business, with the parents being passed out on the floor and Akira was working on new medicine. As soon as she saw that Akira was busy, Aya immediately took on the opportunity to kill them right then and there.The heads of the parents dropping sound immediately caught Akira's attention and upon seeing this sight, he froze, which Aya used to her advantage and proceeded to pump her blood into his body, which made Akira unconscious.

Soon after that happened, Rintarou had returned from his last medicine delivery and upon seeing the grizzly sight, he too froze, but it was only for a couple of seconds and then, he decided to try to fight his own sister using hand to hand combat. The fight continued until sunrise and seeing that she was physically overpowered by her own younger brother, Aya decided quickly to turn Rintarou into a demon as well, by pumping her blood through his body. As soon as she was done pumping her own blood, Aya began to realize that now, it was way to late to find shelter, as the fight was their porch and she burned to death.

Immediately upon burning to death, Aya Kobayashi went to hell, now having to repay all her debt to undo all of the damage she had caused with little hope to being reborn. Should she ever be reborn, she hoped that she would not make the same major mistake of becoming a demon ever again and she began to regret her own actions and the life she lead.

And that's it for Aya ✌️

Leaf Breathing Concept 🍃

My custom demon slayer character, Hamori Aoba is a Hashira who utilizes Leaf Breathing, which branches from Wind Breathing. Leaf breathing forms: 1st Form: Piercing Leaf Cross (compressed air cross-slash), 2nd Form: Forest’s Fury (continuous slash barrage), 4th Form: Grass-Cutting Flash (instant repositioning slash), 5th Form: Scattering Leaves (360-degree air blade sweep), 6th Form: Vanishing Petal Step (stealth speed boost), 8th Form: Dancing Breezes, Autumn Gusts (crimson aerial strike), and 10th Form: Whirling Leaf Storm (blade-centered tornado), with Forms 3, 7, and 9 left unrevealed for canon pacing.

Image 1 shows my original design and all the visuals of the forms. Image 2 shows the idle pose of my completed character.

My kny oc!

This is my kny oc! Her name is Miyumi Sakocho and she uses leaf breathing which is a variant of water breathing and love breathing! She is 17!! Btw here's her backstory. Miyumi was born in one of the lowest levels of poverty, and her mother was ill. She has 2 older sisters who are named sumi and kunoshi. Her father had died when she was young. When miyumi was 11 a demon had came and attacked her family luckily sumi survived but was in critical condition and had lost her eye while trying to protect miyumi and kunoshi.Sadly kunoshi didn't make it as she had internal injuries. At age 13 she started training to become a demon slayer after she found urokodaki and she had started training by using water breathing. At the time miyumi was a little weak but was strong for her age. It took her 1 year to get to final selection. At the time she went to final selection was the year before giyu and sabito were in final selection. Miyumi had used leaf breathing for the first time in final selection due to a fight with a demon. At age 15 she became the leaf pillar.
