Obanai Iguro

Deuteragonist Deceased First: Chapter 44

The Serpent Hashira, who fights with a uniquely twisted nichirin blade and uses his white serpent companion Kaburamaru to relay visual information in battle. Raised by a criminal family that sold him to a demon at birth, Obanai carries profound guilt and has spent his life trying to become worthy of the feelings he has for Mitsuri Kanroji.

Biography & Character Analysis

Obanai was born into a family that worshipped a snake demon, and was marked for consumption from birth — his scars and partially sewn-shut mouth are from the demon's partial consumption of him when he was a small child. He escaped, found the Demon Slayer Corps, and dedicated himself entirely to the Corps to atone for the harm his family's demon caused others. His devotion to Mitsuri is absolute and unspoken for most of the series because he does not feel he deserves her.

The Serpent Hashira

Obanai Iguro is the Serpent Hashira of the Demon Slayer Corps, a stern, suspicious swordsman rarely seen without his white snake Kaburamaru coiled around him. Guarded and severe, he holds others — and himself — to unforgiving standards.

Serpent Breathing

Obanai wields a wavy, snake-like blade and fights with Serpent Breathing, a style of winding, unpredictable strikes that slither past a demon’s defenses. His companion snake aids him in battle, extending his senses and reach.

A dark inheritance

Obanai was born into a cursed family that fed its children to a demon, and he escaped that horror carrying deep shame and self-loathing. That past explains his rigidity and his fierce, protective loyalty to the Corps that gave him a purpose.

Devotion in silence

Obanai’s harsh exterior hides genuine feeling, most of all his unspoken love for Mitsuri Kanroji. His quiet devotion, and his willingness to give everything in the war against Muzan, reveal the warmth buried beneath his severity.
