Tengen: Tengen is a very tall, broad-set young man with a heavy, muscular, lightly tanned skin frame. His hair is white and of uneven length, the longest waves touching his shoulders and is cut with three more prominent, shorter clumps, arching above his eyes on either side of his face to fall as bangs.

Obanai: Obanai is a 21-year-old young man of short stature and a pale complexion. He has straight-edged black hair of varying lengths, the longest reaching down to his shoulders and the shortest stopping at his cheekbones, which he wears down with two shorter strands hanging between his eyes.

Shinobu: Shinobu is regarded as a beautiful, petite young woman with a small frame. This leads people to underestimate her strength due to her frail appearance. She has black hair with purple highlighted tips tied back into a "yakai-maki" bun using a butterfly-shaped pin

Mitsuri: Mitsuri is a voluptuous young woman with a kind face. She has pale green eyes with small moles under each eye. Her most defining feature would be her long hair usually tied in three braids which is pink and fades into neon green halfway through.

Gyomei: Gyomei is a hulking figure among the Demon Slayers. He is one of the tallest characters in the series, easily towering over his fellow Hashira. He is powerfully built and extremely muscular. He has spiky black hair and a prominent scar running horizontally across his forehead.
