Nakamura is chief official at the Ministry of Foreign Affairs and head of Public Security Section 6, where he investigates various mysterious cases. In an effort to solve the case of 2501 (an illegal hacking program), he frequently locks horns with Section 9. He was part of the original movie; however, there is no mention of him in the series. Nakamura is seen once again in the OVA (Solid State Society), in a scene that suggest the Major was working in freelance for Section 6.
