Among the most fascinating Pillars of manga Demon Slayer, Obanai Iguro is distinguished by his rigid temperament and his unwavering loyalty to the Demon Slayer Army. Behind his headband and his Kaburamaru snake, hides a painful story marked by guilt, sacrifice and a discreet love for Mitsuri Kanroji. Let's discover together the complex journey of this emblematic manga character.

His haori and mouth wrap are on our Obanai cosplay.

Obanai's tragic past in Demon Slayer

Obanai Iguro, the Serpent Hashira in Demon Slayer

Obanai was born into a corrupt clan, living off offerings to a snake demon. As a child, he was raised in a cage, destined to be sacrificed. This childhood marked by fear and loneliness forged a tough and implacable spirit. Saved at the last minute by a Pillar, he later joined the ranks of demon slayers, determined to redeem himself by fighting evil.

A destiny shaped by pain

Obanai's destiny is deeply linked to his past. His scars, which he hides under a bandage, are reminders of the horrors he experienced as a child. His severity is not the result of chance, but the reflection of a demand towards himself and others. For him, each fight is a way of atone for the fault of his birth and of affirming his value among the Pillars.

Obanai and Mitsuri: a silent love in Demon Slayer

Despite his apparent coldness, Obanai harbors sincere feelings for Mitsuri Kanroji, the Pillar of Love. Their relationship, modest and touching, illustrates a more human side of the character. Obanai admires Mitsuri's benevolence and joie de vivre, a stark contrast to his own austerity. Their bond becomes a powerful emotional driver in the final battle against Muzan.

A love born from respect and gratitude

Obanai never dared to declare himself to Mitsuri, judging himself unworthy of her because of his past. However, their exchanges of letters and their shared moments testify to a deep affection. Before their death, they promise to meet in another life, free from the weight of demons and past suffering.

Breath of the Serpent: Obanai's signature in Demon Slayer

Obanai masters the Serpent's Breath, a unique technique inspired by the undulating and unpredictable movement of the reptile. His attacks, both precise and rapid, embody the coldness and determination of the character. With Kaburamaru, he even manages to compensate for his partial blindness, proving that he remains a formidable fighter despite his weaknesses.

A fight against yourself as much as against demons

Through his techniques and his rigid attitude, Obanai embodies sacrifice and absolute discipline. His quest is not just that of a warrior, but that of a man seeking to free himself from the shame of his past. His courage in the face of Muzan, until his last breath, makes him one of the most memorable characters in the manga.
