Saotome Kazuya is a computer whiz. One day, his friend Nanbara threatens him with a computer virus. While trying to stop the virus, Kazuya ends up placing a special order. May, a cyberdoll, arrives at his door a few minutes later. She is 1/6th the size of a normal person, which leads to many awkward situations. Not to mention that Kazuya can't even afford to keep May. Cyberdyne is not satisfied with Kazuya's non-payments and will do anything to retrieve CBD May.
