Masamune

The Masamune is a legendary katana from Super Land, notable for its brilliance and length. It is the key that sealed away a curse in Super Land, and once it was stolen by Leon the curse spread, changing the angelic creatures into grotesque avians. It is regarded as having similar power to the Orbs of Nature and gives a potential explanation as to why there is no Orb of Light. Leon was able to perform Light Magic for a brief time in his battle with Zais during the Sea of Sand saga while wielding the blade.
