Sesshoumaru

Sesshoumaru is Inuyasha's older half-brother, a dog-demon defined by his pure bloodline and disdain for his sibling. Driven by a need for power, he hunts for Tessaiga, the sword forged from their father's fang, which he views as superior to the Tenseiga left to Inuyasha. This pursuit leads to frequent, violent confrontations between the two. While initially characterized by cruelty, Sesshoumaru eventually faces his own insecurities and a growing capacity for compassion.
