Kitetsu has a single unique ability that sets it apart from other blades. When the sword inflicts a fatal injury, it will rip the soul from the victim's body and absorb it, preventing the victim from being healed or revived by any means. An absorbed soul will become permanently bonded with the blade after three days. If the sword is ever broken, it will release any and all souls stored within it that have not been bonded and this ability will be rendered inert until the blade is repaired. As souls are metaphysical, there is no limit to the number of souls that the sword can hold. The more souls that are taken, the stronger the blade's curse will become, slowly twisting and perverting the user's body into a monstrous state similar to the Curse Seal, however any modifications are purely cosmetic and will not grant any kind of additional abilities.
Reason for Modification: Learned that soul taking/destroying is a valid ability, more concise ability description, and this fits better than the other effect once the revamp of the character is completed. Specific Modification: Changing ability description and lowering both Strength and Endurance to C-rank.
