originally from Samurai Shodown/Spirits VI, which was a non-canon dream-match game and became a very popular character, to the point that she almost got a game of her own.
She was added in the second wave of DLC fighters for the 2019 reboot, finally adding her to the universe as a proper canon character.
She is a crane who takes the form of a human Japanese maid, and is known to be very loyal to her master. She fights with her two iconic butterfly swords.
