Powers, Skills and Abilities

 * Meidō Zangetsuha: This technique created a path that sent anyone who was hit with it directly to the Netherworld. The technique originally belonged to the Tessaiga after absorbing it from Shishinki. However, Tōga passed it on to Kai in the form of Tenseiga in order to teach him the value of compassion. Originally, the Meidō Zangetsuha manifested as a massive black circle that would send an opponent's entire body and soul to the Netherworld, and left no trace behind. However, when Kai first obtained the technique, the Meidō Zangetsuha took the form of a black crescent portal that only sent a part of a person into the Netherworld along with their soul; stronger opponents were thus unaffected by the incomplete Meidō. As Kai's compassion grew, the Meidō Zangetsuha was strengthened until it became a perfect circle.


 * Meidō Blades: Once Kai completely mastered the Black Tenseiga, the Tenseiga could fire multiple black crescent-shaped portals that not only cut an opponent, but have their remains sucked up into the path. Thus the technique kept its original ability intact while also adding the Tessaiga's cutting nature. It seemed to be stronger than the original Meidō Zangetsuha, as it was able to destroy forever Naraku's body, which was impervious to the original move.
