Sengoku era

Sun of Hashir: Yoriichi was a tall man with a lean, muscular build and long, spiky red-tipped hair that he kept in a ponytail. Unlike his twin, Michikatsu, he was slightly slimmer and had shorter bangs and wavier hair than him. Yoriichi always had a distant and solemn expression, rarely showing emotion.

Yoriichi wore a red haori over a very pale orange nagagi kimono with black umanori-style hakama, a pair of zori with red belts, and white tabi socks, with his Nichirin sword worn on the left side of his waist, as is the custom for most demon hunters. He wore hanafuda earrings, created by his mother as amulets.

Thunder Hashir: Shin is a young man of relatively short stature, with a slim build and fair skin. He has short yellow hair of varying lengths that is cut at the ends, fading to a dark orange color, which falls over his face in jagged bangs. He wears a messy ponytail. He wears a nagagi kimono with white triangles, a yellow and brown gradient pattern, a yellow cloth wrapped around his forearms, and white hakama pants in the umanori style, tied with a white uwa obi, pale brown tabi socks, and white laced zori. Shin wields a standard sized and shaped Nichirin katana with yellow lightning bolts all along the blade. The hilt of his sword is circular in shape with 4 small indentations, the center is silver-toned with small triangles and a gold border. The hilt is yellow and is wrapped with a white silk ribbon. The base of the hilt is gold, with two short white ribbons hanging from it. Along with his katana, Shin comes with a standard white sword sheath.

Luna Hashira: Michikatsu is reserved, silent and aloof, he rarely speaks; when he does, he speaks slowly and emphatically, giving his words more weight and authority. He is a strict follower of rules, punctual. Michikatsu is also shown to be humble, and he does not hesitate to admit his failure or complain about any difficulties. Although, there seems to be something he was seen to have problems with. Only a few people caught a glimpse of this aforementioned problem that Michikatsu had.

Flame of Hashir: Enjuro was a young man of tall stature and muscular athletic build. He was known for his charisma and great optimism, with an enthusiastic smile plastered on his face almost all the time. He had long, bright yellow hair with red streaks like flames, tied in a ponytail along with two chin-length bangs on the sides of his head, black forked eyebrows, and golden eyes that faded into red with white pupils.

Enjuro wore a paler brown version of the standard Sengoku era Demon Slayer uniform, which consisted of a brown kimono jacket, a white cloth around his waist, and tatsuke hakama pants. Over this, he wore another kimono jacket that became progressively brighter from red to bright orange as it went down. Lastly, he wore a red kyahan with yellow flames erupting from the bottom to the top, pale brown tabi socks, and a pair of white zori with red belts.

Wind Hashir: Takeshi is a tall, muscular man with long, wavy black hair with a green tint and a few white streaks. He has large, greenish eyes. On his chest, he has two diagonal scars that form an X, presumably from a battle with a demon. He also has several smaller scars on his face.

He wore a dark green haori, unbuttoned to show off his muscles, as he was incredibly proud of it.

Hashir Stone: Kazuyoshi embodied the gentle giant archetype, being surprisingly quiet and sensitive despite his intimidating appearance. He is also shown to be quite devout, constantly carrying a rosary and staff with him and offering prayers in dire situations. In particular, Kazuyoshi would easily cry over the most insignificant things, highlighting his rather gentle nature. This could be due to his love and compassion for all living things, brought on by his Buddhist upbringing. Like the rest of the Hashira, Kazuyoshi held Oyakata-sama in high regard. He was also one of the most respected people among the Hashira, being a symbol of hope due to his immense strength. Additionally, Kazuyoshi acted as a leader for them, as he was the eldest, strongest, and the first demon slayer appointed by the Hashira.

Hashir Water: Yusuke always had a stoic and unflappable expression. However, he had a reserved personality and a very strong sense of justice with no tolerance for those who did not know their limits and threw their lives away. He showed no hesitation in killing demons and had no respect or pity for them, like most Demon Slayers. Yusuke was extremely consistent. He followed the Demon Slayer Corps' code of conduct without hesitation and was harsh with those who did not. However, he always maintained a cool head. Despite his aloof and stoic nature, Yusuke was protective and caring towards those who were close to him and considered his friends. However, Yusuke never allowed his personal relationships to interfere with his duty, as it would go against his own code. It was briefly mentioned that he considered the Tsugikuni twins, Yoriichi and Michikatsu, to be his own brothers.
