Bakusaiga

Bakusaiga
Bakusaiga is Sesshomaru's signature weapon. The Bakusaiga manifested itself in the hand of Sesshomaru's fully regenerated, and longtime-severed, left arm during his battle with Magatsuhi. This sword has the power to decompose any organic material that its blade comes in contact with, and nullifying any regenerative abilities thereafter. Its effects are extensive as Miroku comments that Naraku would suffer the same affliction should he absorb any demon wounded by Bakusaiga.[6] The blade itself is the manifestation of Sesshomaru's own true power, born from his detachment of InuYasha's Tessaiga. Its birth signifies Sesshomaru's graduation into a full-fledged daiyōkai, which was long compromised by his obsession with Tessaiga. Totosai comments that his ability to manifest his own blade suggests his strength has surpassed that of his father's and connotes his growth through the many trials he endured to emerge as a daiyōkai, with the Bakusaiga serving as the product of this 'rite of passage'. Much like the Tessaiga's Kaze no Kizu, the Bakusaiga can also unleash massively powerful amounts of yōki, enough to slay thousands of demons with one swing. Though similar, Rumiko stated that Bakusaiga's wave attack, which is similar to the Kaze no Kizu, possesses greater power than a full power Bakuryūha from Tessaiga.
