Tyrfing

Tyrfing is the sword Zyeta's Susanoo wields in its right hand. It dons the appearance of a blade of flames similar to a regular Susanoo Sword, and is an enchanted blade capable of utilizing three different effects, all of which stem from the one controlling the ethereal embodiment; Tyrfing's three abilities stem from Zyeta's mastery over the Six Paths of Pain:
 * It is capable of repelling physical objects that hone on its surface in a similar fashion to Shinra Tensei, greatly enhancing the cutting ability of the blade itself. - Deva Path
 * It is capable of absorbing anything composed of chakra in a similar fashion to the Blocking Technique Absorption Seal technique, although does not don a dome. - Preta Path
 * It is capable of tearing out the souls of humanoids it comes into contact with, instantly killing them as a result in a similar fashion to the Soul Removal technique. - Human Path

However the immense boost in power does not come without a price; Zyeta cannot access the abilities of the Paths used by Tyrfing (Deva, Preta, Human) until he removes Susanoo from the battlefield, more specifically the blade itself.
