Sesshomaru is a prominent character in the anime and manga series "Inuyasha." He is the older half-brother of Inuyasha and the son of the powerful dog demon Toga. Unlike his half-brother, Sesshomaru is a full-blooded demon and possesses immense strength and agility. He is known for his striking appearance, which includes long, silver hair and golden eyes, as well as his calm, emotionless demeanor. Sesshomaru initially appears as a cold and ruthless character, driven by a desire for power and disdain for his half-human brother. Over time, however, he undergoes significant development, especially after meeting a young human girl named Rin. Her presence in his life brings out a more compassionate and protective side of him.
