An autonomous waitress doll at Kuroneko-tei Cafe. She’s a hard worker brimming with curiosity. Her program was wiped and now she knows nothing about the world. She likes songs and especially loves to sing and also listen to other people’s songs.

The leader of Kuroneko-tei Cafe. She’s serious-minded, has a strong sense of responsibility and is a tiny bit stubborn. She’s good at looking after others and is loved by those around her. However, she also has a cautious side and doesn’t like new things or unexpected situations.

An ex-reconnaissance autonomous doll. Her artificial body was made to be lightweight and she looks seemingly like a child. She speaks bluntly—a lingering trait from her time working as an army civilian—and uses as few words as possible. She faithfully does whatever she’s told, but beyond that, she has no desire to have any further involvement.

She works in the kitchen at Kuroneko-tei. Her cooking skills are outstanding. She’s a gentle, polite and graceful autonomous doll. She’s always cheerful and is like a big sister who can put others at ease. She enjoys writing and every day she methodically writes in her diary.

An autonomous doll made in Loberia. She receives a research observation request from the imperial army and is sent to Kuroneko-tei. Although her graceful poise exudes refinement, she casually insults others. Being the only one from a different country at Kuroneko-tei, she experiences loneliness from time to time.
