It's 30 December 1999. Utsumi and Bud have returned to Japan to challenge the SV2 again, and sell their team's services in the format of the Griffin. At the SV2, the AV-Zero is going though its paces. It has been improved and is now much faster. Kanuka has returned to Japan to visit her grandmother and has dropped by to visit her former colleagues at the SV2. Detective Matsui discovers that several top Labor specialists are in town and informs Captain Goto of his findings. Meanwhile, Momoko Sakurayama receives a tip-off that several arms dealers are also in Tokyo. She informs Kumagami, who in turn tells Captain Goto. Something big is going to happen. That night the Griffin Labor returns. Division 2 was previously called out to a fire, so Division 1 is called in to deal with the Labor. Bud soon figures out the Zero's weakness: it is programmed to stop near buildings to avoid damage. He takes full advantage of this and defeats both Patlabors.
