Muramasa (Fanon Canon)

Muramasa (村正, "Village-Just") is the  entrusted to the  of.

Powers
Released Form: The power of Muramasa can be awakened by the command "Whisper" (囁け, Sasayake).

Zanpakutō Control: Muramasa possesses the power to freely control the spirits of other. When its ability is invoked, it rouses the primal instincts of the Zanpakutō spirit and causes them to turn on their wielders. In doing so, the spirit is forced out of its wielder's inner world and permitted an existence of their own outside of their. The only way to counter its power and thus resist its influence is to close off one's own heart, for Muramasa's ability works by intruding into the hearts of its victims.


 * Indirect Invocation: Those who are under the control of Muramasa can have their powers and abilities indirectly accessed by the Zanpakutō. It becomes possible for the sword to direct the actions of those under its control, as if the ability they wield belonged to Muramasa.
