Gyomei Himejima, the Stone Hashira: Gyomei is a 7'2 TOWER of a man at 27 years old. he's broad shouldered and extremely muscular. his eyes are pure white since he's blind, though he can sense his surroundings and people's intentions better than anyone with vision can. he has short black spiky hair and a scar across his forehead. he wears a dull yellow haori atop his slayer uniform. he's the strongest human alive, and essentially the leader of the hashira besides Kagaya Ubuyashiki, the head of the Demon Slayer Corps. he wields a heavy, spiked nichirin flail that has its thick chain attached to a nichirin axe head. both weapons are the size of a normal person's torso. despite the immense weight of his weapon, he can wield it like a whip casually due to his ungodly strength. he is stoic, respectful, humble, and can tear up over things that strike him as sad or beautiful. when he unlocks his Slayer Mark, his forearms get covered in a broken, cracked stone-like marking that spreads from his wrist to elbow. this amplifies his strength IMMENSELY, allowing him to contend with the likes of upper moon 2 and 1 for an amount of time. in this state, it may be possible for him to beat upper moon 3 alone.

Sanemi Shinezugawa, the Wind Hashira: Sanemi is a 5'11, lean and muscular 21 year old man with white hair, pale purple eyes, and scars littering and covering his entire body. his Slayer uniform doesn't have buttons, leaving his chest uncovered. his uniform's sleeves are rolled up to his elbows and his white haori matches. sanemi wields a black-green nichirin katana. is aggressive, skeptical of things, and gets annoyed easily, but he's also very grounded. he's cocky in fights and wants to destroy ALL demons. he's tactical in battle and very observant, even to a point of recognizing his own weakness as to not hold back someone like Gyomei in a fight. despite all of this bravado, he deeply cares for his brother, Genya, and can awaken his Slayer Mark simply by getting pissed enough to do so.

Tengen Uzui, the Sound Hashira: Tengen is a 6'6, 23 year old man who's shockingly agile for someone as insanely built as himself. he has long white hair that's typically tied into a ponytail behind hidiamond-plated headband with a string of diamonds framing his face on either side. his eyes are a deep maroon. there's a maroon colored marking around his left eye similar to a tattoo. he wears a sleeveless version of the Demon Slayer corps uniform without a haori and has golden rings around his biceps. he wields two flashily colored/decorated nichirin cleavers, each as long as a katana but broad enough to split boulders with ease. they're chained together at the handles, allowing tengen to utilize them in tandem to perform multi-layered attacks, deflections, or spin them like a buzzsaw. he is a trained shinobi with poison resistance and extreme agility, and happens to be one of the more experienced Hashira besides Gyomei. tengen has 3 wives and will protect them at all costs. he loves flamboyant, intriguing things, is very outspoken and loud, and loves exhilarating fights.
