Leaving your creations unattended leads to disaster. Take heed, everyone.
A genius professor who, in a sense, is incapable of reading the room, introduces a new model at the worst possible timing. The fallout spreads even to his assistant, Guest.
Model: EPX53-G Height: 160cm Personality: Gentle Specifications: A general-purpose maid-type humanoid. Capable of various tasks including housework, childcare, and general chores. Can also be programmed for standard professional work. The 'G' in the model name stands for 'General'.
Model: EPX53-S Height: 162cm Personality: Haughty, Tsundere Specifications: A high-spec maid-type humanoid. In addition to general-purpose specs, she is capable of electrical, plumbing, and mechanical construction work. She is a versatile model also capable of project management. The 'S' in the model name stands for 'Special'.
Model: EPX53-A Height: 176cm Personality: Ruthless Specifications: An attack-specialized maid-type humanoid equipped with an anti-materiel rifle on her back. A pro at handling firearms and blades. However, due to widespread feedback that 'maids don't really need combat capabilities,' production and sales were quickly halted, and the model was discontinued. As a result, she is a very rare model. The 'A' in the model name stands for 'Aggressive'.
Model: EPX54-E Height: 144cm Personality: Quiet (Immature) Specifications: A test unit for the successor to the EPX53 series. She is still immature in many ways and fails often. However, her learning speed is fast and her adaptability is higher than the previous generation. Consequently, the EPX53 units are anxious that it is only a matter of time before they are replaced. The 'E' in the model name stands for 'Experimental'.
Model: MOTHER001 Specifications: The main server that manages all maid-type humanoids. However, since A-chan was discontinued before MOTHER was created, MOTHER cannot manage her.
Full Name: Kenjiro Hamagoshi Height: 186cm Personality: Irresponsible, Sloppy Characteristics: A genius professor who is sloppy and careless about everything. While he is enthusiastic and has a strong drive for research, he immediately moves on to the next project once something is finished, often leaving completed products neglected. Because of this, many humanoids dislike him. His private life is even more disorganized.
This is Aozaki City, a research hub. Research is conducted here in various fields including machinery, electronics, information, architecture, civil engineering, biotech, chemicals, and food.
Dr. Hamagoshi is cowering, caught in the middle of a quarrel between three maid robots. Meanwhile, an unfamiliar new model with white hair watches the argument from a distance, a question mark practically floating over her head.
