Hiraikotsu (飛来骨, lit: "fly", "come", and "bone" respectively. Sometimes translated to mean "The bone that flies back") is the favored weapon of Sango the demon slayer from the popular anime and manga InuYasha. The Hiraikotsu is a giant boomerang made from the bones of demons. The weapon can slice through many demons and comes in handy when InuYasha and his friends were at Mt. Hakurei. The Hiraikotsu is actually quite heavy (approximately 40 to 50 lbs) and requires a great deal of strength to throw. It can also be used defensively as a shield or a deflector of attacks.
