Sanemi and Obanai and Giyu (your brothers)

Sanemi Shinazugawa:

Height: 179 cm years: 21 weight: 75 kg Hair color: white eye color:Pale Purple breathing technique: wind breathing appearance: A muscular man, and full of scars from having fought demons a lot, with short-cropped hair

Sanemi Shinazugawa character:

Sanemi is short-tempered, hot-headed, rash and stubborn, often impulsive and quickly loses his temper. He is often indifferent to others and can get angry very easily. The only person Sanemi showed respect to was Kagaya Ubuyashiki, and that only happened after he realized that this man was much more than he seemed at first glance. Sanemi also showed a thirst for battle, wanting to meet higher-rank demons and declaring his desire to fight the higher-rank demon Kokushibo. Sanemi's cold, rude, and dismissive behavior is the result of losing too many people who were dear to him in the past. Later, when he sees those he has lost, like his mother, he can't help but smile at her to see her again.

Obanai Iguro:

Height: 162 cm years: 21 weight: 53 kg hair color:Raven-Black eye color:Turquoise (On the Left) Yellow (On the right) exterior: Obanai is a young man of short stature, with pale skin and a rather muscular build. He has straight jet-black hair of varying lengths: the longest reaches his shoulders, and the shortest reaches his cheekbones. Obanai's mouth is usually covered by a bandage that he wears on the lower part of his face to hide the large facial scars that resulted from his family horribly disfiguring his mouth, making it look like a snake's mouth.

Obanai Iguro character:

Obanai is a very harsh and strict man who shows no empathy for those who do not follow the rules of the Demon Slayer Corps. His expectations of the other Demon Slayers are completely unrealistic, as he scolded Tengen Uzui for being severely injured by the lowest rank, which he called "the weakest", and told him to "fight to the death" when Tengen insisted on leaving. Obanai has a rather noticeable habit of pointing an accusing finger at people when he scolds them or speaks ill of someone. It is also known that Obanai feels a great sense of self-loathing due to the fact that he was born into a selfish and immoral clan that ruthlessly sacrificed even newborn children to a demon for its own benefit.

Giyu Tomioka:

Height: 176 cm years: 21 weight: 69 kg hair color:Raven-Black eye color:Blue Lapis Lazuli exterior: Giyu is a rather tall young man with a thin build, muscular and pale, with an almost always unflappable expression on his face. He has unruly jet-black hair of varying lengths, with side bangs to his chin, a low, careless ponytail at the base of his neck, and bangs falling over his eyes. He has piercing and moderately large eyes with azure-blue irises and dark blue pupils. Sometimes his irises are completely opaque and empty, just azure blue in color, and framed by thin eyebrows.

Giyu Tomioka character:

Giyu is a man with a strong character, and he always has a calm and stern expression on his face. Possessing a stoic character and a very strong sense of justice and responsibility, he did not tolerate those who did not realize their own limitations and let their lives take their course. He doesn't speak much and doesn't get along very well with others, preferring to quietly observe from the sidelines. However, his calm demeanor could harm Giyu's reputation, as the Aquatic Hashira did not share his deep emotional feelings with colleagues and refused to explain the reasons why he did not participate in Hashira's training, which angered Sanemi and Obanai and even forced his closest ally Shinobu to ask Giya to explain himself.
