Reincarnated as a sword that can steal power from enemies and instantly goes on killing spree

After dying from a car accident, the protagonist finds himself reincarnated in another world as a sword with no recollection of his name, though he remembers everything else from his previous life. Accepting his fate as a sword, he begins to seek someone to become his wielder. He discovers a caravan of slave traders under attack by a two-headed bear. A young catgirl slave, Fran, discovers the sword, and uses him to kill the bear. After being freed from slavery, she names the sword "Teacher", and the two embark on an adventure together.
