Sesshomaru

Sesshōmaru (殺生丸, "Destruction of life") is a powerful dog daiyōkai and feared throughout the feudal world, as well as the supporting character in Inuyasha series. He is the half-brother of the hanyō Inuyasha and the first son to the Inu no Taishō, their father. Unlike many other yōkai, he has no interest in possessing even one shard of the Shikon no Tama to enhance his powers. On his journey, he is accompanied by a two-headed dragon named A–Un, a demon imp named Jaken, and an orphaned human girl named Rin. Eventually, Rin's smile is what caused Sesshōmaru to redeem himself.
