As the Serpent Hashira, Obanai’s sword perfectly reflects his Serpent Breathing style, his precise combat techniques, and his tightly controlled personality.

This article explores the design, symbolism, and meaning behind Obanai Iguro’s Serpent Sword.

Who Is Obanai Iguro?

Obanai Iguro is the Serpent Hashira of the Demon Slayer Corps.

He is known for his:

• Strict personality
• Strong sense of discipline
• Sharp judgment
• Absolute dedication to his responsibilities

Although he often appears cold and critical, Obanai is deeply loyal and carries strong feelings beneath his guarded personality.

His sword reflects the same qualities: controlled, complex, and always ready to strike.

What Kind of Sword Does Obanai Use?

Obanai uses a unique Nichirin katana designed specifically for Serpent Breathing.

Unlike ordinary swords, his blade features:

• A twisted, snake-like edge
• A wave-shaped profile
• A lavender-colored Nichirin blade
• A design inspired by serpentine movement

The unusual shape makes his weapon instantly recognizable among the Hashira swords.

Why Obanai’s Blade Looks Like a Snake

The most famous feature of Obanai’s sword is its curved, irregular blade shape.

The design resembles:

• A snake’s body movement
• Coiling and twisting motion
• Sudden changes in direction before striking

This visual style perfectly matches Serpent Breathing, which focuses on unpredictable attack paths and precise movements.

The Meaning Behind the Lavender Nichirin Blade

Obanai’s Nichirin sword changes into a lavender color associated with Serpent Breathing.

The color represents:

• Elegance combined with danger

Unlike bright and aggressive sword colors, lavender creates a feeling of mystery and restraint — matching Obanai’s personality.

How the Serpent Sword Matches His Fighting Style

Serpent Breathing focuses on:

Obanai’s curved blade enhances the visual feeling of this style.
