Name: Chiyoko Yamamoto (Chiyo-chan)
Doll Model: Volks DDH-07 on DDS
Age: a few months old
Birthday: November 13
Chiyoko is a simulacrum created by students of the Japan branch of an alchemy school; Rhiannon Yamamoto got into the middle of it somehow, and that created a connection between her and Chiyoko, which is why Chiyoko claims Rhi`s last name.
Having only been created a month or two ago, she is still learning about her own personality.
Unfortunately, after a few months she ran out of power to live; Rosaire had been helping, and when Chiyo disappeared, he fell into a deep sleep.
