Shishou

師匠

A former Japanese person reincarnated into a mysterious sword that rested on a pedestal in the center of certain hidden ruins. After "awakening," the sword quickly learned to move and fight independently using magic, discovering it could absorb a monster's core to increase its strength.
After accumulating some power, it grew bored and decided to leave the ruins to explore new lands, but became trapped in a mana-depleting zone and lost its freedom for several weeks. Eventually, a black cat beastkin slave found it by chance while fleeing from a monster, and the sword helped her regain her freedom. As a result, both decided to continue together, and the sword bestowed upon the girl a name (Fran) and a contract that shares its abilities with her. Fran, in return, named the sword Shishou (Master).
Shishou eventually also summons a familiar and names it Urushi, which ends up serving as Fran's familiar as well.
He also gains the ability to create doppelgangers of himself, which resemble his former human self.
