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.

The remains of Division 1's Labors return to the hanger. Noa is somewhat scared of the prospect of having to fight the Griffin again, but Asuma assures her that she can defeat it. Meanwhile Schaft's section chief is livid at Utsumi's actions. Goto asks Kumagami about her relationship with Utsumi. She tells him it is none of his business. Bud leaves the ship where the Griffin is being hidden to visit the SV2. He doesn't go into the hanger to meet them, and stops at the gate because he is worried that Goto might spot him. He is later chewed out by Utsumi because of his actions. Kurosaki notices that Bud is becoming more dangerous and secretly orders to place a bomb on the Griffin without Utsumi's knowledge. If it looks like the Griffin will be captured Kurosaki will destroy the Griffin and Bud. Matsui notices that the labor specialists are on the move. They are in fact being taken on a bus en route to the Griffin Labor's next show. Utsumi notices Matsui trailing the bus and manages to give him the slip. The Griffin appears that night, 31 December 1999, and Division 2 are mobilized. Meanwhile Kanuka is taking her grandmother on a trip. On the train she overhears a news report about the Griffin surfacing again in Tokyo bay. Her grandmother senses her anxiety and tells her to go and that she will be fine by herself.

The children's TV program Together With Mother has finally been axed after 20 years, and is about to begin its final broadcast. Unfortunately, one of the cast members, Kumagoro, a man in a bear suit, has decided to take the rest of cast hostage by grabbing them with a small a Labor. He demands ¥300,000,000 and a helicopter or he'll blow up the cast. To prove his claims, he sets off a car bomb in the parking lot. Division 2 are called in, but the producers of the show seem to want to prolong the situation in order to get higher ratings. Kumagami and Noa enter the studio disguised as waitresses in order to free the hostages, but the plan does not go well. The riot police are called in after Division 2's failure, but Goto thinks they'll just inflame the situation more. However, Goto does have a plan which is so bizarre it might just work.

The Griffin is ready to fight Division 2. Momoko Sakurayama races to the scene, but a traffic jam is holding them up. She decides she can wait no longer, and runs to the scene without her camera crew. Meanwhile, the Ingrams face off the Griffin across a bridge. In the ensuing battle, the Griffin escapes off the bridge into the water and Ota shoots a hole into the bridge with the shotgun in an attempt to hit it. But the Griffin pulls Ota's Labor down through the hole. Ota manages to escape, but his Labor is at the bottom of the bay. Kanuka returns to the SV2 hanger to retrieve Unit 3. She is determined to help her comrades, but will she make it to them in time? Momoko finally arrives at the scene to report on the action, but Goto and Kamagumi have other plans for her and her camera crew. They ask her to film the windows of the hotel where the fight is taking place. Goto believes that the Labor specialists are watching the show inside the hotel. He wants to be able to identify them. Utsumi orders Bud to fight Noa. Bud smashes Noa's Ingram back onto its carrier. Noa's Labor is flat on its back, and Bud is coming in for the final blow. Worse yet is the fact her battery is running out.
