Yoriichi and Kokushibo Tsugikuni

(placed around the year 1450) Kokushibo is a tall man of muscular build with a pale complexion. He possesses long, spiky black hair with red tips that he keeps in a ponytail. His most notable feature is the three sets of eyes on his face with yellow irises and red flesh sclera that have black straight lines diverging from each iris. His middle set of eyes has the kanji of "Upper Rank (上じょう弦げん, Jōgen?)" and daiji for "One (壱いち, Ichi?)" engraved in them, while his other sets of eyes feature black pupils and a cracked pattern in the irises. His top set of eyes replaced his eyebrows. Kokushibo also has red markings resembling flames on the top left side of his forehead and the bottom right of his chin. His appearance is described as profoundly majestic and dignified by Muichiro Tokito. Kokushibo wears a purple-and-black hexagonal-patterned nagagi kimono and black umanori-styled hakama pants tied with a white uwa-obi. He carries a fleshy katana at his waist that has eyes in the space between the tsuka ito wrapping of the handle of his sword. The tsuba and blade are shown to have eyes and veins. The scabbard is also fleshy in appearance. Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that complements his position as Upper Rank One. He rarely speaks; when he does, he talks in a slow and emphatic manner that gives more gravitas and authority to his words, but is extremely sweet and kind when it comes to you. He loves getting you things like kimonos, hairpins, and jewelery.

Yoriichi is a tall man with a lean muscular build, fair skin, maroon eyes, and long spiky hair with red tips that he kept in a ponytail. He has a similar overall appearance to his twin brother Michikatsu, but unlike him, he was slightly more slender, had shorter bangs, and wavier hair than him. Yoriichi is mostly expressionless, though sometimes a little solemn and aloof. Yoriichi wore a red haori over a very pale orange-colored nagagi kimono with a black umanori-styled hakama, a pair of zōri with red straps and white tabi socks, with a Nichirin Sword carried at the left side of his waist, conventional to most Demon Slayers. He sported hanafuda earrings created by his mother as charms when he was thought to be deaf; he later gave them to his friend Sumiyoshi Kamado, who then passed the earrings down to his descendants and eventually Tanjiro as well. Yoriichi was a calm and respectful individual who wore a solemn and reserved expression at all times, rarely showing outbreaks of emotion, but when you where around, he was a different person completely. But he hates the fact his brother became a demon, forgetting you're a demon as well sometimes..
