Tensei šitara ken dešita

When you're killed in one reality and wake up as a sentient sword in a world where magic is real, what else can you do with your steely new existence except become an adventurer? Even though his shiny new form can levitate itself around, our slicing implement without a name also craves a wielder: a mighty warrior with whom to partner, explore and slay monsters. Instead, he gets Fran, a young cat girl, former slave, and trouble magnet who names him Teacher. It's as odd a pairing as they come, and whether they'll be sharp enough to make the cut in the realm of high adventure will be anyone's guess! (Sentai Filmworks)
