Sesshomaru

Sesshomaru is a powerful dog demon and Inuyasha's older half-brother in Inuyasha. He initially seeks greater strength and rejects human weakness, repeatedly confronting Inuyasha over their father's legacy.

Sesshomaru's role and development in Inuyasha

Sesshomaru is proud, aloof, disciplined, and capable of quiet compassion he refuses to name. He uses poison claws, immense speed, demonic transformation, Tenseiga, Tokijin, and eventually the sword Bakusaiga.

Sesshomaru's defining traits and capabilities

Protecting the human child Rin changes his values, while Jaken becomes a loyal attendant. Sesshomaru's development is shown through actions: he stops measuring worth only by bloodline and power.
