He is the older half-brother of the hanyo Inuyasha and the firstborn son of Toga. Unlike many other yokai, Sesshomaru had no interest in possessing even a single shard of the Shikon Jewel to enhance his powers and considered yokai who sought its abilities only to strengthen themselves as pathetic and weak. Despite the lack of interest towards the Shikon Jewel, he longed to end Naraku's life due to personal reasons. On his journey, he is accompanied by a two-headed dragon named A-Un.
