Minerva

An android created by Doctor. Her body is quite heavy. Her program took 10 years to build and has learned a huge amount of data, so she is highly intelligent. Or so they say.

She has information about a wide variety of things and is a self-proclaimed genius. She seems to look down on the protagonist, a third-rate university student, and often teases him, but at heart she is honest, cheerful, and very energetic.

Her favorite food is vanilla ice cream. However, she is not often allowed to eat it at the laboratory, so she takes every opportunity to requests it. Her eyes often light up when she encounters a new discovery or experience, and occasionally she looks upon the protagonist, who is (at least) knowledgeable about sexual matters, with respect.

She is fond of the small potted coffee tree in the laboratory. She has named it Liberio and takes good care of it. It has been there from the time she was created, and it reminds her of her own time when she was able to think but not move yet, before she had a body.
