||InuYasha's older half-brother
Sesshomaru (殺生丸 Sesshōmaru?) is InuYasha's older half-brother, aged nineteen in appearence and mindset. As a full-blooded demon, he is extremely powerful, easily invulnerable when fighting, and is able to fly in the air like "Ah-Un." Sesshomaru's hair is long and silver like InuYasha's, only it appears to be a little longer. Unlike most demons seen in the series of The Anime and Manga, he shows no interest in possessing any of the Shikon Jewel Shards, feeling confident of his own strength and seeming to find the use of the gem to enhance one's power distasteful. He is initially ruthless in dealing with InuYasha, whom he hates as a half-demon who consorts with humans, and attempts to steal the sword Tetsusaiga from him. He even had a sword forged from the fangs of Hoshinki, an incarnation of Naraku, that sliced the Tetsusaiga into two, knowing that this will match the Tetsusaiga's power. This sword's name is Tokijin, which later gets destroyed by Moryomaru. However, Sesshomaru gradually becomes more sympathetic and caring after meeting the human child Rin, who never shows any fear of Sesshomaru's demon-self. Even going as far as using Tenseiga to revive her, Sesshomaru becomes a guardian to Rin, coming and opting to Rin's aid whenever she's in trouble, while Rin is considered as his ward. His growing compassion and the reaction of the Tenseiga to Sesshomaru's compassion for Kagura and her slow death prompts the master swordsmith Totosai to reforge Tenseiga, enabling the Meidou Zangetsuha ("dark path of the dawn's moon blast") attack. After Naraku attempts to manipulate him by using Rin as a hostage, Sesshomaru becomes determined to destroy Naraku as his main goal. He eventually gains his own blade that is a manifestation of his own power, the Bakusaiga, made by Totosai in the Manga. In the Anime, he is voiced by Ken Narita. In the English dub, he is voiced by David Kaye and by Michael Daingerfield in the Manga.
At the end of the Manga, Sesshomaru becomes Kagome's brother-in-law and has Rin staying with Kaede in the village, but he still continues to pay her a visit in a regular basis. Jaken also continues to travel with him.
