| At first, the sword was surrounded by such a massive evil aura that it actually possessed Kaijinbou when he held it. The evil of the sword basically came from Goshinki's deep lingering desire to kill Inuyasha. Kaijinbou eventually dies from his dual with Inuyasha though the sword remained to be contained with evil- so much so that no one was capable of touching it. When Sesshoumaru arrived to claim the sword, he was warned by Toutousai to not touch it or else he would also be possessed and controlled by the evil within. However, we soon see that Sesshoumaru surprised everyone by his ability to effortlessly surpass Toukijin's evil energy and gain control of the sword to use as his own. The evil aura dissipated and finally, the sword has chosen its master. In the few times that Sesshoumaru actually drew the sword out, we're able to see an amazingly great power pour out of it. The sword's mere energy/pressure is capable of cutting the opponent without even striking them. In fact most of the time, Sesshoumaru doesn't even touch Inuyasha with it. He just holds it out and all the cackling energy comes out of it and in turn cuts Inuyasha with the sword pressure. |
