Kirakishou (雪華綺晶 Kirakishō?, Schöner Schneeblüten Kristall, Sparkling Snowdrop Crystal) (spelled Kirakisho in the Tokyopop translated manga)

The true seventh Rozen Maiden doll. Both her hair and her ornately ruffled dress are white, as indicated by Shinku's description of her in volume 6 of the manga, and by the remodeled version of the original manga. However, she has been shown with a pale pink dress (anime), pale pink hair (Rozen Maiden AliBat, a fan-created fighting game), or both (the cover of volume 6 of the manga). Kirakishou's right eye is missing. In the anime, a layer of tissue covers the right eye socket and a single white rose grows from it, but in the manga, she simply has a rose growing out of the empty eye socket, as described by Shinku: "Her left eye can see everything, but reflects nothing, while her right eye is an empty hole, with a white rose growing out of it." In the anime, Kirakishou's shoulders are not ball jointed as the other dolls' are, presumably because she is an entity that only exists in the N-Field.

Kirakishou's first appearance in the manga is in volume 6, but is not properly introduced until volume 7. In the anime, however, she has not been formally introduced. Her only anime appearance was towards the end of the finale of Rozen Maiden Träumend; she is shown for only a few seconds.

In the manga, Kirakishou claims that the seventh doll lacked a physical body and could only exist in the N-Field. Because of this, she destroys and consumes Hinaichigo so that she can use the sixth doll's body to materialize outside of the N-Field. Even though Kirakishou could not initially exist in the real world, she could still affect real world events; she gives a rose ring to Odille Fosset, the granddaughter of Corinne Fosset, Hinaichigo's former mistress.

Kirakishou offers her Rosa Mystica to Suigintou in volume 7, in order to trick her "big sister" and take Megu. Suigintou, however, refuses to accept the Rosa Mystica, saying that she would take it later on her own terms. During her first encounter with Shinku, in volume 6, Kirakishou parrots whatever Shinku says, much like Barasuishou does in the anime.

Because Kirakishou's appearance in the anime was merely a headshot, her abilities remained unknown there. However, in the manga she controls white rose vines, manipulating them to restrain her opponents or violently lash out at them as if they were whips. Also, the vines make up a spider web-like structure with which Kirakishou crawls (literally, like a spider) through the N-Field. The rose vines are also used as a mean to anticipate Kirakishou's entrance or simply to foreshadow her creeping presence, especially when wrapped around some unsuspicious character. Finally, Kirakishou can trap people's consciousness into the N-Field, sealing them into white crystals. As seen with Odille, one of her victims, people whose soul has been trapped fall into a deep slumber in the real world, likely dreaming something Kirakishou herself conjured to keep them at bay. Apparently, this is also done due to Kirakishou's far greater need of power, which a single medium would not be able to provide.

In the manga, Kirakishou appeared towards the end of the series, when she devoured Hinaichigo from the inside-out to gain physical substance. Offscreen she managed to corner and trap almost every other doll and medium. By masking herself as Jun, she also sent parts of Souseiseki's lifeless body to the Jun of an alternate reality where he never wound up Shinku nor encountered any Rozen Maiden, where she appeared as a true doll for the first time. It is explained that Kirakishou was voluntarily left without a body by Rozen himself, who wondered if leaving her as a disembodied spirit would grant her superiority over the other Rozen Maidens and achieve greater perfection. Indeed, inside the N-Field Kirakishou is almost omnipresent and far exceeds her sisters in terms of power, but being nothing more than a ghost apparently took a toll on her mind: she is depicted as almost insane, polite yet ruthless and often creepily grinning, driven by extreme jealousy of her sisters' qualities granted by their physical bodies. Her belief is that by obtaining a physical body donned with the unique aspects of every other Rozen Maiden would make her truly perfect. It is however questionable on how malicious she might really be, as while flailing at Shinku and Suigintou she surprisingly pleaded to "hold me more".

Given the fact that it was Jun who assembled her, Kirakishou adresses him as master and wants to form a contract with him, displaying her disturbed thoughts by allowing him to choose which Rozen Maiden would be form a contract with, but not letting him fulfill said choice if it does not contemplate her. She also offered him the power to change his past if he would form a contract with her, though Shinku claimed this to be only a ruse. After Jun kissed Souseiseki's ring, Kirakishou's features started to waste away, given the fact that the body she was using was Souseiseki's. If this meant her demise is unknown, though in her last known act, Kirakishou asked in vain for Jun's help.
