Saotome Kazuya is an expert in computer programming. Nanbara, his pal, threatens him with a computer virus one day. In order to stop the infection, Kazuya places a specific order. May is a cyberdoll that appears at his door a few minutes later. She is one-sixth the size of a regular human, which causes numerous embarrassing situations. Not to mention Kazuya's inability to pay to maintain May. Cyberdyne is fed up with Kazuya's nonpayments and will go to whatever length to reclaim CBD May.
