Sesshoumaru, Inuyasha’s half-brother, stands out as one of the most complex and beloved characters in the series. At first, he appears as a ruthless demon determined to claim Inuyasha’s sword, Tessaiga. However, over time, Sesshoumaru undergoes a profound transformation, evolving from a cold-hearted being who despises humans into a compassionate father.
Here are 9 fascinating facts about this character!
1. Pure-Blooded Demon Heritage

Like Inuyasha, Sesshoumaru is the son of Toga but from a different mother. While Inuyasha is a half-demon, Sesshoumaru is a pure demon, inheriting powerful bloodlines from both parents. This pure heritage fuels his pride and disdain for the weak, especially his half-brother Inuyasha.
2. Wields the “Life-Saving” Sword Tenseiga

While Inuyasha inherits the powerful Tessaiga, Sesshoumaru receives Tenseiga from Toga, a sword capable of reviving the dead but useless against demons. Initially, Sesshoumaru dismisses Tenseiga as worthless, but he later learns to use it to protect those he cares about.
3. Unique Companions

Though often solitary and distant from Inuyasha, Sesshoumaru has his own companions: the two-headed dragon A-Un, the small demon Jaken, the human girl Rin, and Kohaku, Sango’s younger brother. This group plays a key role in softening Sesshoumaru’s personality and nurturing his compassion.
4. Indifferent to the Shikon Jewel

Sesshoumaru sees anyone chasing the Shikon Jewel as weak. His true motivation is to grow stronger on his own terms. His goal is not to possess magical items but to surpass his father’s power.
5. Hunting Naraku Alongside Inuyasha

Despite their complicated relationship, Inuyasha and Sesshoumaru share a common enemy: Naraku. Naraku initially exploits Sesshoumaru’s pride to fight against Inuyasha. However, after understanding their father’s message and witnessing Naraku’s evil, Sesshoumaru joins Inuyasha in hunting him down.
6. Possesses the Power of a Great Demon Lord

As his character develops, Sesshoumaru gains the strength of a high-level demon like his father. He acquires a powerful new weapon, Bakusaiga, which appears alongside the regeneration of his left arm. Bakusaiga can tear apart and annihilate demons, making Sesshoumaru an unstoppable force.
7. Two Tragic Loves

Sesshoumaru’s two potential romantic interests both end in tragedy. The first, Sara Asano, whom Sesshoumaru was fascinated by, died at his hands after transforming into a demon to be closer to him. The second, Kagura, died just after escaping Naraku, turning to dust before Sesshoumaru’s eyes.
8. Rin’s Gentle Influence

Rin, a human girl, plays a major role in changing Sesshoumaru’s character. Thanks to her, he learns to care and love, evolving from a demon who despised humans into a compassionate father figure.
9. Father of Half-Demon Twins Setsuna and Towa

In the sequel Yashahime: Princess Half-Demon, it is revealed that Sesshoumaru is the father of the half-demon twins Setsuna and Towa. This is confirmed by Setsuna, who was trained by Kohaku for ten years while Towa disappeared into the future.
