Sakuya

The most advanced version of the maid doll produced by Maid Works. Her body is identical to that of one of the dolls Yui threw away, and it turns out that that doll contained a microchip capable of recording the stresses it received, thus allowing the manufacturing company to create a life-size replica while preserving its previous memories. Since Takaya was the one who created her, she is very close to him. Voiced by Ai Shimizu.
