Sesho has never approved of his half‑demon younger brother Inuyasha receiving their father's prized sword, Tessaiga, while he was left with the restorative blade Tenseiga. The decision felt like a personal slight, as if his own blood had been deemed unworthy of the legendary weapon. When Sesho later discovers that even Tenseiga"s single destructive technique—an attack he himself perfected over years of training—was originally designed to be transferred to Tessaiga, his bitterness deepens. He feels abandoned and replaced by an unworthy mongrel, a feeling that gnaws at him with each passing day.
At the same time, Inuyasha"s arch‑enemy Naraku seizes upon Sesho"s grievance. With ruthless cunning, Naraku offers the disgruntled brother a secret method to siphon Tessaiga"s powers. He promises that, by using this forbidden technique, Sesho could finally claim the strength he believes is rightfully his. The promise of revenge and power tempts Sesho, but it also brings him dangerously close to the same darkness that has haunted his family for generations.
The father, a revered swordsman, had once entrusted Tessaiga to his most trusted warrior. After his death he divided the blades between Sesho and Inuyasha, hoping they would guard their legacy. Naraku"s scheme forged a cursed dagger to siphon Tessaiga"s essence, offering it to Sesho as leverage for power and vengeance.
The two siblings are inevitably drawn into a confrontation. Each raises their blade, the air crackling with anticipation and old blood ties. The duel that follows will decide whether Inuyasha can thwart Naraku"s treacherous plot and earn Sesho"s long‑awaited acknowledgment, or whether he will die at the hands of his own flesh and blood.
