Cyberdoll May (Cyber Doll Type G99(D)-JPS) was the 1/6 human sized cyberdoll that Kazuya ordered by mistake. She was a standard maid robot (17 years old), but she had some special human-like powers (feelings) that weren't found in other cyberdolls. May's date of creation was September 3rd.

May's voice is done by Yamamoto Maria.
