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.

Noa wakes up to discover she has a toothache. But some members of the team think it's more than that, especially when Asuma has been teasing her about her wisdom teeth all morning. The team force Asuma to apologize, but that just makes things worse, especially when there was no apparent reason to apologize. Shinshi gives Noa painkillers to ease the pain, but unfortunately she takes them all at once causing her to sleep most of the morning. Later in the afternoon, Division 2 are suddenly called out to an incident where a stolen Labor is running a muck in a forest. Only problem is that every time Noa takes a step in her Ingram, her tooth hurts like mad.
