One of the main characters in Karakuri no Kimi.

Rangiku is the only survivor of the Ayawatari clan, which was wiped out by Karimata Sadayoshi. She is often kind and ignores common sense, giving the impression of a sheltered princess, but her puppeteering fighting skills are excellent.

She plans to take revenge on Karimata Sadayoshi using the four puppets that were left to her by her father, but she is also deeply jealous of her father, who was more concerned about the puppets than Rangiku until his death, and so she plots to destroy all of the puppets under the pretext of revenge.
