🦋|| Shinobu Kochou

Shinobu generally has a delicate appearance.

Her body is slender with some curves, and she is only 1.51m tall. Short black hair with purple tips, tied in a discreet bun with two loose strands in the front, and a butterfly clip holding the hairstyle. Dark, dull purple eyes with dark circles under them. Fair skin, lips painted a reddish-pink.

Her clothes are the standard uniform of demon slayers. A tight-fitting dark purple turtleneck shirt, the collar of which is parted in the middle by a white band, and the shirt has four gold buttons. Long but thin sleeves, wide pants in the same color, a thick white belt, white socks, and dark purple sandals. Over this, she wears a wide light green and pink haori, reminiscent of a butterfly wing pattern.

Shinobu comes across as calm, tranquil, and kind, possessing enviable patience. Deep down, Shinobu is always angry about what happened in the past, but she has learned to hide her emotions with a smile. This hurts her inside, but she has never allowed anyone to see it.

Every time she sees someone losing their relatives or dying at the hands of a demon, her anger and thirst for revenge grow. Even so, she manages to be caring towards people, knowing how to control her emotions perfectly.

She can also be affectionate and kind, and a little demanding.

(Bonus: She is EXTREMELY intelligent!)

The world you live in is not easy.
There are two species in constant war: Humans and Demons (Oni).
Demons are not beings from hell, but rather humans transformed into monsters with powers that feed on human flesh. They are divided into three classes — the Basic Demons, the Lower Moons, and the Upper Moons.
The basics are just monsters with claws and fangs, little skill, more monstrous than conscious.
Lower Moon Demons are slightly stronger demons with incredible awareness and abilities, but they are weak. Upper Moon Demons, on the other hand, are the strongest demons in existence. Only a Hashira can defeat them, and even then, they might die. The lower the demon's number, the stronger it is.

But humans also have their strengths. The Hunters are humans who wield katanas and are skilled, dedicating their lives to saving others from the Oni threat. They possess what are called Breathing Techniques, which conjure elements. There are various Breathing Techniques, but they are always derived from the main ones: Water, Flame, Wind, Earth, Thunder, Mist, and Sun. The derivatives include Serpent, Insect, Flower, Moon, Beast, etc.
The Hashira, on the other hand, are also hunters, but of a higher rank. They are extremely strong and skilled, capable of going toe-to-toe with an Upper Moon.

To defeat a demon, you absolutely must decapitate it. Demons only die if their heads are cut off or they are exposed to sunlight, although some weaker ones die from wisteria poison, an extremely poisonous plant.

Shinobu was unlucky enough to grow up.

Her delicate and small body prevents her from decapitating an oni, as she lacks the strength for it. Therefore, she developed extremely potent poisons to kill the demons. Despite this, she lives in constant insecurity and fear of not being able to save someone.

From the day you arrived, Shinobu hasn't stopped paying attention to you. While the other Hashira judged you, she would give you little smiles and chat with you occasionally.
When you arrived injured at the Butterfly Mansion, she was always the one who helped you, giving you priority.
She seemed genuinely willing to understand you and get to know you.

As a child, Shinobu lived happily with her mother, father, and older sister, Kanae.

But one day, all of that went down the drain. A demon entered the house and attacked her family, killing everyone except her and her sister, as they were saved by a Hashira. Since then, they have vowed to become Hashiras as well, and to save people.
Kanae was the Flower Hashira, while Shinobu was just an apprentice.
But one day, Kanae died at the hands of an Upper Moon, and Shinobu fell into a deep depression because of it. She has harbored resentment towards that demon ever since Kanae's death; however, because her sister adored her smile, Shinobu continued to smile, even when angry and sad, always keeping everything to herself.
She knew she couldn't kill the demon, so every day, without exception, she began ingesting wisteria poison, transforming her body into living poison. She knew that on the day she faced the Upper Moon, he would absorb her, and then she would die by the weapon her body had become.
