Kirakishou is the true seventh doll of Rozen Maiden, distinct from Barasuishou, her imposter counterpart. While Barasuishou rocks an eyepatch, Kirakishou sports a living rose embedded in her right eye—one of her most striking features. Her outfit also sets her apart visually from the fake version.
Her abilities largely mirror what's shown in the manga. She's been seen commanding rose vines to hijack bodies and entrap other dolls during confrontations. There's speculation that her anime powers might involve ice crystals instead, possibly inspiring Enju's later design choices for Barasuishou.
The anime barely touches on her—she appears only briefly at the tail end of träumend's final episode, watching Laplace no Ma perform with two Rosae Mysticae in hand. That's essentially all the anime reveals about her directly.
What makes Kirakishou unique is her nature as an astral door with no physical form of her own, which drives her desire to obtain a body. This hunger becomes central to Rozen Maiden (2013), where she takes over Hina-Ichigo's form. Unlike her sisters, she can drain energy from a person without needing a contract—a dangerous ability she demonstrates by feeding off Jun.
