While under the effects of the Spirit Transformation Technique, the user is capable of creating a mirror lithograph from the ground, which can then change into a perfect copy of the one whose reflection it catches, with the exception of the user's. The copy has the appearance, abilities and weaknesses the target had before the lithograph was created. When the copies are defeated, they shatter like mirrors, to which Muchitsujo refers as a harbinger of "seven years of bad luck".
