However, later in the series it gains the ability Meidou Zangetsuha. This is an attack that creates a black portal that forces whatever it touches to be sent straight to hell. At first his Meidou is in the shape of a crescent. But as he grows in his knowledge of the technique Sesshoumaru creates a giant oval shape. Finally, after reacting to the nearby Tetsusaiga it takes on it's perfect circle shape.
This technique is later discarded when Sesshoumaru breaks the Tenseiga over the Tetsusaiga, thus transferring the attack to the Tetsusaiga.
