==Summary==
 is a major supporting character of Kimetsu no Yaiba. He is a Demon Slayer of the Demon Slayer Corps and the current .
He 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. 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. When he turned twelve, Obanai was finally allowed to leave his cell for the first time in his entire life and was introduced to the demon who decided to wait until he was a little bigger to eat him.
Obanai escaped from his cage and fled with the demon pursuing him but he got saved by the then Flame Hashira, Shinjuro Rengoku, the father of Kyojuro Rengoku. Realizing the threat that demons posed to the world he became a Demon Slayer and eventually the Serpent Hashira of the Demon Slayer Corps.

|-|Abilities=
*Superhuman Physical Characteristics
**Acrobatics
**Body Control & Regeneration (Low - With Total Concentration Breathing, one can stop hemorrhages, and can manipulate his blood flow)
**Statistics Amplification (Total Concentration Breathing increase the user's speed and power to match demons. His Demon Slayer Mark further increases his power and speed)
**Transparent World: Perception Amplification, Information Analysis, Enhanced Sight, Analytical Prediction, and Enhanced Precognition (Transparent World makes his perception of time slow down and makes the user directly see their opponent's muscles, blood flow and movements which allows them to predict their next moves)
*Supernatural Willpower
*Extrasensory Perception (Able to sense the presence of others and malicious intent. Muzan stated that Hashira could in the Entertainment District right away)
*Battle Spirit, Limited Fear Manipulation & Paralysis Inducement (Overwhelming Aura that causes the opponent fear and paralysis with them feeling the air getting heavier, and can even cause internal bleeding and external lacerations)
*Instinctive Reaction (Comparable to Kyojuro, Mitsuri, Sanemi, and Giyu who can react instinctively)
*Pressure Points (Was able to pin down Tanjiro in a way that restricted movement or breathing)
*Kaburamaru:
**Animal Manipulation & Precognition (To compensate for being almost blind in his right eye, Obanai uses his snake Kaburamaru to read enemy attacks and then relay that information to himself. Used Kaburamaru to fight Muzan and predict his attacks even after being rendered completely blind)
*Master Swordsman and Limited Elasticity (Is one of the strongest and most skilled swordsmen in the entire Demon Slayer Corps. Can match opponents who have over a century worth of combat experience. Was the one to teach all the other Demon Slayers in the Demon Slayer Corps sword revision. Can make a normal wooden sword bend, weave, and extend in impossible ways)
**Sunlight Absorption (The ore of his katana (Scarlet Crimson Ore) absorbs sunlight. The amount of sunlight his weapon has absorbed is so great that Kokushibo's katana would burn and break off before it could cut through)
**Perception Manipulation (Users of Breathing Styles can create seemingly elemental effects)
**Shockwave Generation (Breathing Styles allow sword forms to strike from a longer distance)
**Bright Red Nichirin Sword: Heat Manipulation & Regeneration Nullification (Bright Red Blades emits heat and is capable of inflicting wounds that burn on the cellular level, hampering demon regeneration)

Resistance to:
*Fire Manipulation, Water Manipulation & Heat Manipulation with Demon Slayer Corps Garbs (Demon Slayer Corps Garbs protect against fire, water and cold)
*Poison Manipulation (Total Concentration Breathing grant resistance to poison and the ability to slow its circulation)
*Biological Manipulation (Users of Total Concentration Breathing are resistant to Muzan's blood which can immediately transform normal humans into demons with a scratch, leading them to require a few days to willingly transform. Can resist Muzan's injected blood which rapidly attacks and destroys cells leading to quick melting and vaporization, especially with the Demon Slayer Mark)
*Pain Manipulation (Was willing to continue fighting after suffering crippling injures and intense damage)
*Fear Manipulation &Paralysis Inducement (Unaffected by the aura of Lower and Upper Ranks which caused intense shuddering and lack of air)
</tabber>
Attack Potency: Building level+ (Should be comparable to Base Mitsuri), higher with Demon Slayer Mark (Stronger than before. Cut Muzan's arm whip, something only Gyomei who's the strongest Demon Slayer in his era was previously able to do. Cut Muzan's neck twice, only failing to do lasting damage due to his regeneration. Helped Tanjiro parry Muzan's arm whips while guided with his snake), even higher with Bright Red Nichirin Sword
Speed: Massively Hypersonic (Comparable to Base Mitsuri), higher with Demon Slayer Mark (Can parry hits from Muzan, continuing to do so even when he was blinded, using only his snake to guide him), even higher with Transparent World
Lifting Strength: Class 5 (He was stated to be a little weak when it comes to arm-wrestling, though he is strong enough to pin Tanjiro to the ground with Tanjiro stating that he is not able to move)
Striking Strength: Building level+, higher with Demon Slayer Mark, even higher with Bright Red Nichirin Sword
Durability: Building level+, higher with Demon Slayer Mark (Could take a very casual hit from Muzan, even going back to fight whereas Gyomei, Sanemi and Giyu remained incapacitated. Stopped Muzan from eating his head off)
Stamina: Superhuman (Superior to Tanjiro who endured extremely taxing training for seven days non-stop with no food, no sleep, and only a small amount of water from rain, later drained for even greater stamina, was also getting injured frequently during the training session. Far superior to Inosuke who can hunt for 3 days. Hashira can train for months through training that almost puts them on the verge of death. Fought Lower Rank-level demons in the Dimensional Infinity Fortress for nearly 5 hours on top of fighting Nakime. After being hit by Muzan's attack and being influenced by his blood he could still fight, unlike his fellow Hashira, Mitsuri, who was greatly affected by the same attack. Continued fighting Muzan even when both his eyes were cut out, and being badly bitten. Lasted the longest in the Muzan fight)
Range: Extended Melee Range; Several Meters with Breath Styles
Standard Equipment: Twisted Nichirin Katana (A blade made from metals that absorbed the light of the sun, they cause demons to completely disintegrate if they are decapitated with them, as they are weak to sunlight, which in the case of demons which have assumed a form where they don't have a neck or head in the traditional sense can be done by slicing something that's equivalent enough to the neck, demon limbs that are sliced off and constructs created through Blood Demon Arts that are bisected through a Nichirin sword are also subject to the disintegration, stabs and slashes with a Nichirin sword can dispel the effects of Blood Demon Arts and can temporarily weaken a demon's power and abilities if directed at the neck), Demon Slayer Corps Garbs (Protects from the claws and slashing attacks from weaker demons, and resistance against fire, water and cold), and his serpent friend, (Obanai, having always been partially blind in his right eye, developed a combat technique utilizing his pet snake Kaburamaru. Kaburamaru possesses a unique ability which allows him to read and predict a target's 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 effectively. Kaburamaru also seems to be capable of understanding human speech and emotions, as he understood Tanjiro's instructions to grab Yushiro's paper talisman and later shed tears when watching Obanai and Mitsuri pass away. Kanao herself stated that Kaburamaru was exceptionally clever)
Intelligence: Gifted (Should be comparable to Sanemi and Giyu. Created his own Breathing Style that made use of a unique weapon)
Weaknesses: He is almost blind (became fully blind when fighting Muzan), albeit Kabamaru helps to guide him in battle.
