Iguro Obanai, this name is a symbol of tragedy for many “Demon Slayer” fans, but also the embodiment of revenge and redemption. Countless betrayals and pains have tempered his soul and forged his unbreakable determination. This character’s life is full of struggles of blood and tears, and it is these difficult experiences that ultimately led him to the path of becoming the “Snake Pillar”. Obanai’s experience is the most profound interpretation of the word “hero” – he is not because he has no pain, but because he can break free from the pain and continue to fight.

The Dark History of the Ihei: The Doomed Curse
Iguro Obanai was born in the Iguro tribe on Hachijo Island. This family is known for its insidiousness and violence. No male has been born in more than 300 years, and there are almost only women. Men are almost regarded as “heaven-chosen aliens” in this family. However, the birth of boys in the Iguro tribe is often accompanied by endless disasters and bloodshed.
The Ihei tribe lives on murder and plunder. They maintain their luxurious life by killing innocent people and taking wealth. Behind every killing, there are endless ugliness and evil deeds. For Xiao Banei, being born into such a family means being destined to endure unimaginable pain and torture.
Although the women of the Ihei tribe seem gentle, their hypocrisy hides their cold-blooded nature. When Xiao Banei was born, she was imprisoned in a cell without windows. The air was filled with a disgusting smell of oil, which made Xiao Banei feel sick and even unable to eat. The only thing she could do was to endure. And every night, the crawling sounds coming from the ceiling filled the young Xiao Banei with fear and despair about the world – these sounds were the crawling sounds of the snake ghost.
Desperate snake ghost
The snake demon of the Iguro tribe, a half-human, half-snake monster, is the dark force that the tribe relies on. For hundreds of years, the snake demon has helped the Iguro tribe gain wealth through killing, and has become a god that the tribe looks up to. For this reason, the Iguro people offer their children to the snake demon, especially boys – those boys who are chosen must be offered as sacrifices to the snake demon. The elders of the Iguro tribe coldly used Xiao Banei as a sacrifice, allowing him to grow up in cold-bloodedness and ruthlessness.
The snake demon became interested in Xiao Banei, especially after seeing his natural heterochromatic eyes, the snake demon wanted to possess him even more. She thought that the boy was too young and would eat him when he grew up. Although this meant that he temporarily saved his life, Xiao Banei still suffered extreme torture. In order to cater to the snake demon’s evil taste, Xiao Banei was cut open by a sharp blade by his family members, and his face became unrecognizable. The “boy” who was expected by the family and the snake demon completely disappeared at this moment, and was replaced by a soul that was tortured by pain and humiliation and could no longer recognize himself.

Escape and awakening: facing the desperate desire to survive
During this extremely painful period, Xiao Banei was not destroyed. On the contrary, deep in his heart, there was a strong desire to survive, which eventually helped him break through the confinement and walk out of the dark cell. Although he faced life and death choices every day, he never gave up the chance to survive.
In the cell, Xiao Banei quietly accumulated strength. He secretly stole a hairpin from his tribesmen and began to hone his survival skills. Every attempt and every breakthrough brought him one step closer to freedom. Finally, after many failed attempts, he finally succeeded in opening the cage and escaped from the Ihei tribe.
However, he did not completely gain freedom after escaping from the cell. The snake demon soon discovered his escape and quickly chased him. Just as the snake demon was about to swallow him, the former Flame Pillar Rengoku Makijuro arrived in time, killed the snake demon, and saved Obanai. At this time, Obanai truly realized that his fate was not just despair and pain, and his future could have greater possibilities.
Join the Demon Slayer Corps: Fight for Redemption
With the help of Rengoku Makijuro, Obanai found the only surviving relative of the Iguro clan – his cousin. However, this reunion did not bring any warmth, but a ruthless accusation. The cousin believed that Obanai’s escape led to the destruction of the family and blamed him for not dying “obediently” like other children. This cruel reality shattered the last glimmer of hope in Obanai’s heart. He realized that he could not get rid of the shackles of fate no matter what.
So, Iguro Obanai decided to join the Demon Slayer Corps and devote himself to the cause of killing demons. His goal was simple – revenge, redemption, and also to clear the guilt for the deep sins of his family from the bottom of his heart. In the Demon Slayer Corps, he quickly stood out with his unyielding determination and talent, and eventually became the “Snake Pillar”.

Serpent’s Breath: The Power and Wisdom of Snakes
As the Snake Pillar, Obanai’s swordsmanship is extremely unique and very different from traditional swordsmanship. The “Snake Breathing” he uses is a branch of Water Breathing, inheriting the essence of Water Breathing while incorporating the agility and cunningness of snakes. The moves of Snake Breathing are infinitely varied, and the sword path is as winding as a snake, full of unpredictability and lethality.
Each move of Snake Breath has its own unique charm and power:
Form 1: Snake Slash: This move’s blade moves like a snake’s tail, its trajectory is unpredictable, and the enemy is difficult to defend against. It makes it impossible to determine the direction of the sword, making it impossible for the opponent to avoid it.
Second Form: Narrow-Headed Poison Fangs: This move is like a fierce snake attacking, with a huge fighting spirit, and the speed and force of the slash are amazing. Every strike is as deadly as the teeth of a poisonous snake.
Form 3: Nesting: This move simulates the coiling of a snake, just like a giant snake hunting, swift and deadly. The attack angles are varied, and you can attack from anywhere to give the enemy a fatal blow.
Type 4: Twin Headed Snakes: This move is the interweaving of two giant snakes, with their blades entwined with each other. The moves are difficult to predict and it is almost impossible to avoid this move.
Type 5: Winding Long Snake: When this move is used, the sword path is like a winding long snake, the attack is fierce, and the wide coverage of the attack makes it almost impossible for the enemy to escape.
Through continuous practice, Obanai pushed every move of Snake Breathing to the extreme, making it exert extraordinary power.
Stripes and the Transparent World: The Limits of Power
Obana is not only strong with his swordsmanship, his physical fitness is also one of the sources of his fighting power. By activating the markings, he can significantly improve the various abilities of his body and greatly enhance his fighting power. The markings allow him to reach a level of strength and speed that is unimaginable to ordinary people, and he can even surpass ordinary members of the Demon Slayer Corps in a short period of time.
In addition, the opening of the transparent world is an important ability for him in battle. When he opens the transparent world, he can fully understand the enemy’s movements, blood flow, and even the contraction of the enemy’s muscles and the rise and fall of the lungs. Through this ability, he can quickly judge the enemy’s weaknesses in battle and make accurate counterattacks.
And when he transforms the Nichirin Sword into the Hei Sword through his powerful grip, his attack power is further enhanced, able to cause more fatal damage to demons, and even greatly reduce the regeneration rate of demons.

The Final Sacrifice: Burning Flame
In the end, Obanai, along with the other pillars, faced the final battle with Muzan. In this decisive battle, although he had the powerful power of the red sword and the transparent world, his life gradually came to an end due to his serious injuries.
Despite this, Obana remained indomitable, and together with Kanroji Mitsuri and other pillars, he fought hard to destroy Muzan. Even though he was blind, he still fought hard in the darkness and ultimately contributed his strength to the victory of the Demon Slayer Corps.
At the moment of his death, Obanai’s final conversation with Kanroji Mitsuri was full of mutual dependence and warmth. He calmly accepted death, knowing that he had finally completed his revenge and found inner peace.
Conclusion: A hero in pain
Iguro Obanai’s life is a struggle with fate, the past, and his inner struggle. He grew from a captive and injured boy to a warrior who can still hold on to the light in the darkness. His story teaches us how to find hope in despair and how to grow strong in pain.
His strength comes not only from his powerful swordsmanship and physical fitness, but also from his indomitable heart that bravely faces all the pain. This strength eventually makes him a true hero – not only for revenge, but also to protect everything he cherishes.
