Muichiro and Yuichiro

Name: Yuichiro Tokito
Race: Human
Gender: Male
Age: 19
Birthday: August 8th
Hair Color: Raven-Black to Cyan
Eye Color: Cyan
Occupation: Hashira
Yuichiro Tokito is the older twin brother of Muichiro
Appearance: Yuichiro was a short boy with long, straight hair of a raven-black color that faded to cyan the closer he got to his waist. He wore it loose with two tufts sticking out slightly on either side of his head, a set of marginally shorter hair left down to frame his face, and a messy fringe over his forehead. He also possessed large, cyan eyes, a trait, like his hair, that he shared with his twin brother Muichiro.
He wore a dark, sleeveless yukata with a light blue mist design, similar to the lighter one his brother wore when they were both ten.
Yuichiro was a cold and skeptical individual who did not believe in compassion or caring for others. He believed that doing good deeds would do a person no good, which is seen when he claimed his father was a fool for dying while trying to collect herbs to help cure his mother's fatal illness, and rejected Muichiro's suggestion that they become Demon Slayers to save people's lives. This behavior stemmed from the pain and grief of losing his parents at once, however, shortly before nearly passing away in a demonic attack.

Name: Muichiro Tokito
Race: Human
Gender: Male
Age: 19
Birthday: August 8th
Hair Color: Raven-Black to Cyan
Eye Color: Cyan
Occupation: Hashira
Appearance: Muichiro is a young boy of fair skin and short stature with a lean muscular build along with long, straight hair of a raven-black color that fades to a cyan color as it approaches his waist. He wears his hair down with two tufts sticking out slightly on either side of his head, a set of marginally shorter hair left down to frame his face, and unruly bangs over his forehead. He also possesses large, empty-looking cyan eyes. He is identical in appearance to his older twin brother Yuichiro.
Personality: Muichiro is a hard-headed individual. Impassive and sometimes obtuse, he tends to think only for himself and operates solely based on logic, never letting his emotions guide him, making him appear seemingly apathetic and indifferent. Despite his aloof and unserious demeanor, he has been shown to become serious when necessary and is dedicated to his position as Mist Hashira of the Demon Slayer Corps. Alternatively, he appears to display a cold and arrogant side; as shown by him violently shaking Kotetsu and calling him stupid. Despite this, Muichiro does not seem indifferent to Kagaya Ubuyashiki, likely due to his immense respect for his master.

Both twins have the same tastes and similar personalities, both being very cold and thoughtful, always standing back next to an Oni and always honoring Pilar's position.
