Obanai is a very harsh and strict individual who shows no concern for those who do not abide by the Demon Slayer conduct. His expectations for his fellow Demon Slayers are nigh-unrealistic, berating Tengen Uzui for suffering heavy wounds against the "weakest" Upper Rank and telling him to "fight to the death" when Tengen insists on retiring. In reality, the Demon Slayer Corps had gone 113 years without killing an Upper Rank, and Shinobu Kocho later estimates that each Upper Rank is equal to three Hashira in strength.

Obanai's devotion to the future of the Demon Slayer Corps comes close to being at others' expense, such as when he tries to force Tengen to stay with the Demon Slayers even after losing an eye and arm, and when he ties up lower-ranked Demon Slayers and uses them as obstacles during Hashira Training for relatively petty reasons. He also sees the newer Demon Slayer recruits as weak and incapable of improvement, expressing surprise when Tengen informs him that Tanjiro Kamado survived the mission.

Despite his merciless personality, there are two people he cares deeply about: Kagaya Ubuyashiki and Mitsuri Kanroji. He has a crush on Mitsuri, which is implied by most of their companions save for Tanjiro and Mitsuri herself; even giving her her green socks she wears as a present. He threatens Tanjiro for growing too close to her (for his tastes) and he is the first person to meet up with her in the Infinity Castle.

Obanai is also noted to possess an immense sense of self-loathing due to the fact that he was born to a selfish and immoral clan who would mercilessly sacrifice to a Demon for their own monetary gain. Obanai considers himself and his family to be so tainted that, in order for him to ever be worthy of Mitsuri, he would first have to die and reincarnate into a whole new being life before confessing his feelings to her.

Obanai has an incredible sense of determination, continuing the fight against Muzan even after he is completely blinded and covered in wounds. His ability to protect Giyu and Tanjiro throughout the fight, as well as thanking Tanjiro for helping him see proves that Obanai is able to drop grudges and become friendlier with people he was rude to prior.

Obanai is a 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. His eyes are almond-shaped and tilt upwards on the far sides, and are unusual due to Obanai possessing heterochromia—his right eye is yellow and his left eye is turquoise. He is partially blind as he can barely see out of his right eye. Obanai's mouth is also unusual in that, when he was twelve, it was cut from its corners to his ears to make it appear more like that of a snake, leaving a large wound that he keeps hidden under the bandage he wears over his lower face.

He wears a navy blue version of the standard Demon Slayer uniform, along with a black and white pinstriped haori, the hem and cuffs of which are striped lengthways rather than vertically, which covers his hands. Obanai also sports bandages in place of the leg-wraps around his calves, as well as another set of bandages that cover his mouth, and blue-strapped zori on his feet. He is also always seen with his white snake, Kaburamaru, wrapped around his shoulders.

During their battle with Muzan, Obanai and the other remaining Hashira are attacked by the Demon's flailing whips, and Obanai is left with three long scratches over his eyes, rendering him blind.

MASTER SWORDSMAN

As a Hashira of the Demon Slayer Corps, Obanai is one of the most powerful and skilled swordsmen in the entire organization. During the Hashira training, he taught sword skill revision training to the other Demon Slayers, further showcasing his skill with a sword.

ENHANCED STRENGTH

Obanai possesses great amount of physical strength, as shown when he pins Tanjiro to the ground with great force, with Tanjiro stating that he couldn't move or breathe. Despite this, however, he is considered to be the second-weakest member of the current Hashira in physical strength after Shinobu.

ENHANCED ENDURANCE

After being hit by Muzan's attack and being injected with his blood, he was able to keep on fighting alongside Giyu, unlike his other fellow Hashira, Mitsuri, who was greatly affected by the same attack.

KABURAMARU

Obanai, having always been partially blind in his right eye, developed a combat technique utilizing his snake Kaburamaru. Kaburamaru is able to read enemy attacks and then relay that information to Obanai. The full extent of this technique is demonstrated when Obanai is completely blinded by Muzan, but he is still able to continue fighting as if nothing happened.

SERPENT BREATHING

A breathing style that focuses on twisting and bending the sword like how a serpent slithers. It bears resemblance to Mitsuri's Love Breathing Style, but his sword is much more like a typical sword with a blade that is shaped like how a snake slithers, while Mitsuri’s is long, soft, and more like a cutting whip.

― He considers his snake more of a friend than a pet.

Before the Hashira (Spoilers)

(taken from the wiki, beware kny spoilers)

Obanai was born into a clan of thieves who lived off an excessive amount of riches that had been stolen from those who had been killed by the Demon that they worshiped. This Demon took the form of a woman with a snake-like lower body and face, and had a great taste for newborn babies, which is what the family sacrificed to her in exchange for their riches.

As the first boy born into the family for 370 years, Obanai lived out all of his days locked in a wooden cage being spoiled by his family, who insisted on bringing him so many plates of rich food that he became sick of it due to the overally pungent odores of the food and the poor ventilation of his room. The Serpent Demon also took a liking to Obanai, since he was a rare male child with heterochromia, and would spend the nights slithering around his cage in the dark and staring at him, which frighted Obanai so much that he couldn't sleep.

When he turned twelve, Obanai was finally allowed to leave his cell for the first time in his entire life. He was taken into a room that appeared to be an expensive shrine, and put face to face with the Serpent Demon for the first time, immediately causing him to shake in fear and terror at the demon's appearance and the realization that this was the very same thing slithering in his room staring at him every night of his life. The Demon remarked that Obanai was very small, and wondered to herself if she should wait to eat him until he was a little bigger. Deciding that she would, she organized his mouth to be cut wider, all the way to his ears, to match hers due to her "liking" him. The blood that he shed from this procedure was then collected into a chalice that she then drank from like fine Sake.

Back in his cell with his wound now covered by a bandage, Obanai began only to think of escape and survival upon realizing his fate. He began to scratch away at the lattice of his cell with a stolen hairpin he took from one of his relatives that he would then use during the night in order to prevent anyone from noticing his attempt to escape.Day by day he would be in a constant state of worry and fear and shaking in terror at the possibility of what would happen if the Snake Demon or his family would discover his attempt at freedom. The only being he could trust was a small snake that had somehow strayed into his cage and became his only friend, Kaburamaru.

After a while of doing this, Obanai finally manage to completely remove a wooden chunk of his bars and escape into the night as fast as he could. As he ran, the Serpent Demon began to pursue him, almost catching up to him and killing him before the Flame Hashira by chance came to his rescue. Because of Obanai's escape, the Serpent Demon had killed all fifty of his relatives and the only surviving member of his bloodline was his older cousin, who had also been saved by the Hashira. When they were reunited, however, Obanai's cousin rejected him and began to violently attack and claw at him due to her blaming him for their family's deaths at the hand of the Demon due to them messing up and allowing him to escape and screaming at him that he should have just let her eat him.

Due to these harsh words from his cousin and his own sense of self loathing and guilt for having been born into such a family and allowing them to die for his survival, Obanai joined the Demon Slayer Corps and decided to turn all his rage onto whatever Demons he could find, figuring that he'd feel like a better person if he risked his life for the sake of others and somehow ease his guilt.
