After the Dog General's death, his second son, Chisaku, navigates between demons and humans as a half-demon, protecting his young brother Inuyasha and opposing the forces coveting the Shikon Jewel. As he goes, he gradually uncovers the mystery of his origins and the Jewel's beginnings.
The flames of war in the Sengoku era have died down, and time and space fracture. Chisaku, a modern medical student whose memories have been altered, transmigrates unexpectedly to the Sengoku era, where demons rule in divided territories. There, he discovers that he has become the most secretive 'second son' in the bloodline of the Dog General, Toga: Chisaku, a half-demon who shares a bloodline curse with Sesshomaru and Inuyasha.

Sesshomaru's poison claws cannot sever the shackles of blood ties, and Inuyasha's Tessaiga cannot shatter the cycle of reincarnation. The three brothers are forced to face the shadow of Toga across time and space: skeletons in the tombs of the Western Lands that are exactly like them, a vision of Sesshomaru's future wandering at the end of the Netherworld Road with Rin's corpse in his arms, a hospital in the modern world collapsing under the corruption of demonic seeds... When the Mandrake Demon's eyes reflect three hundred
