What is Tenseiga?
History of Tenseiga
The Tenseiga (天てん生せい牙が, "Heavenly Rebirth Fang") is a daiyōkai sword that was owned and wielded by Sesshōmaru throughout the main story, and was originally wielded by his father Tōga. It was revealed that Tōga ordered Tōtōsai to forge this blade by departing the Meidō Zangetsuha from the original Tessaiga so that he'd be in possession of two swords which Tōga could give to his sons, one for each. The sword had a special property in it that it could not harm or kill any living beings however, it was able to cut and badly injure beings from the realm of the dead. In the world of the living, its power lay in the fact that Tenseiga could resurrect the dead and heal the wounded. Tenseiga allowed a compassionate wielder to see and slay the beings from the underworld, as well as bringing up to 100 beings back to life in one swing. Additionally, while Tenseiga was unable to harm humans, it was able to kill beings that were not from the world of the living, such as spirits, hell hounds, the undead, and other creatures that were native to the Netherworld. Tenseiga had a slight form of sentience, as there could be seen at various points where it was communicating with Sesshōmaru, and expressed to him things such as a desire to be drawn or prompted him toward certain actions for the benefit of others; namely young Rin.
