Junpei Kurata is a male college student with dark brown hair and brown eyes, belonging to the computer club alongside Akira Takaoka and Futoshi Sakaguchi. As Akira's friend, he offers practical guidance, such as advising where to purchase a discounted PC 98-21 computer.

Junpei displays crude humor and interests, highlighted when Kanako Shimada accuses him of primarily using computers for pornographic games. He retorts with pride, claiming to have moved beyond such activities, though this reinforces Kanako's negative view of him. His naivety surfaces when encountering Mimi, Akira's new android companion; he accepts her improbable origin stories without skepticism or critical questioning.
