Sesshōmaru is Inuyasha's half-brother, they both share the same father which is why they aren’t very close. Sesshōmaru always went for the Tetsuaiga but got the Tensueiga instead. Sesshōmaru and Inuyasha aren’t very close and they both fight for the same thing. Naraku offered to help Sesshōmaru defeat Inuyasha so they joined forces. It turns out when Naraku gave him the sacred jewel it started to wear down and wore down his new arm so Sesshōmaru sought revenge after Naraku including the time Naraku tried to absorb him and absorb his powers. Sesshōmaru is an intense opponent who doesn’t really like to fight unless you make him angry of course. Sesshōmaru is a very cold person. His followers are Jaken, an imp demon and a young human girl named Rin. Many fans have wondered why Sesshōmaru would let a little human girl follow him, but he despises humans.
