Uta is a Japanese robot with the appearance of a young female humanoid. Her birthday is allegedly February 5, which was the beginning of the UTAU project in 2008. She has a cool and friendly personality, but her alleged bullying towards Momo makes her unpredictable. She appears lonesome and melancholic. Her eyes are usually half opened.

Momo is a Japanese robot with the appearance of a young female humanoid. She is designed as a maid and housekeeping robot, but she can also sing. Her attitude is described as being sincere, obedient and shy; she also does things at her own pace. She is also sensitive, so she can be made happy, mad, sad, etc. by the influence of just little things.

Case was a robot created in the image of the Twitch streamer CaseOh. The project was intended to reflect the humor, happy-go-lucky personality & values of what his origins are. His creation was to bring fun & joy into the world, while also caretaking orphaned cats. Empathetic and a gentle giant, he has a sensitive soul and has an air of whimsy and happiness to him with everything he does. He has incredibly sensitive night vision, allowing him to both find and comfort kittens in need that are either orphaned on the streets or alternatively, helping from shelters where there is the potential to be put down. He brings them to an orphanage, a safe haven for them.
