Mina

Mina is a being supported by Takuma Kosugi, and serves as both his partner and robot companion. She is a more affordable product than the "Super Mina" model, primarily handling household chores such as cooking and dishwashing. Mina features a simple body with exposed metal frames, an unchanging face, and communicates through a speaker. She is equipped with internet access capabilities, allowing her to perform tasks from searching for words to handling exchanges via mobile phone.

Interestingly, Mina sometimes exhibits behavior that cannot be entirely calculated, such as gazing at a ring from Takuma Kosugi for long periods. Although she is a robot, Mina lives with Takuma Kosugi as a "common-law wife." She previously experienced being abandoned by a former owner but eventually met Takuma Kosugi thanks to a fortunate turn of events. Her former owner was dissatisfied with her size, lack of facial expressions, and movements that lacked human-like qualities, so they sold her to a recycling shop in order to purchase a new model. Even so, Mina accepts that she is a low-priced model and feels happiness in being able to live together with her new owner.
