InuYasha: Kuroi Tessaiga

Sesshoumaru has long resented that his half-demon younger brother, Inuyasha, inherited their father’s treasured sword, Tessaiga, while he was left with the healing blade Tenseiga. That bitterness deepens when Sesshoumaru discovers that Tenseiga’s lone offensive technique—one he mastered himself—was meant to be passed on to Tessaiga, fueling his sense of being cast aside in favor of someone he deems unworthy.

Sensing an opening, Naraku exploits Sesshoumaru’s anger by offering a way to seize Tessaiga’s power. Drawn into Naraku’s scheme, the brothers are driven into a decisive clash—one that will determine whether Inuyasha can stop the plot and win Sesshoumaru’s recognition, or fall to the blade of his own kin.
