Ogre’s force, Hyakki, participates in a space combat mission. Near the end of the fight, a Leo NPD sneaks up on Do-Ji’s Geara Ghirarga, but he’s saved at the last minute by teammate Rose. Ogre then activates the Ogre GN-X’s Trans-Am and destroys a Pegasus ship to end the mission and clear it with a new record time. A teammate named Nuts asks Do-Ji if he’s really Ogre’s brother, and Do-Ji thinks about the Break Decal he acquired from Tsukasa. At school, Riku and Yukki talk about GBN and wonder how far Break Decals have spread and who is giving them out. Momo finishes a soccer match and asks them if their Battle-Random opponent has been announced. It’s a monthly Force Battle event where the opponent, objective and location aren’t known when you register for it. The game matches forces together based on their rankings. The announcement arrives at the Build Divers’ Force Nest that they’ll be fighting at the Arctic base from Gundam 0080 against Hyakki. Yukki wonders if they should cancel since Ogre and Do-Ji were dubious characters, but Riku feels fired up by the opportunity to face Ogre again with all that he’s learned. Koichi thinks that Riku can handle Trans-Am now, but Riku insists that he won’t use Trans-Am. At the Hyakki base, Ogre comments that Riku isn’t the same as before, and Do-Ji vows to beat him up. Riku explains that he misjudged his own strength and damaged the 00 Diver, and since then he’s wanted to be strong enough to win without Trans-Am. Ayame asks what Riku will do if Ogre uses Trans-Am, and Koichi notes that Trans-Am has disadvantages, but everyone vows to help Riku. Later, the Build Divers take off in their Gunpla and head for the Arctic base on a mission to defend the shuttle launch from Hyakki. Sarah hangs out with Magee, who notes that the Build Divers will lose if their Gunpla or the shuttle are destroyed. The members of Hyakki launch from a submarine.
Koichi’s Galbaldy Rebake is stationed atop a canyon, and he notes that the key in base defense is to lure the enemy where you want them to go. The base’s anti-air system and their sniper types can take out aerial attacks, leaving two crevasses and an underground water channel that can access the shuttle launchpad. Explosives detonate and seal the channel, forcing Hyakki to the two crevasses, where they come under ambush from the GM III Beam Master and Momokapool. Do-Ji rushes off on his own to find Riku. Rose’s Jagd Doga Thorn is attacked by Ayame’s RX-Zeromaru, and Ogre dodges collapsing ice blocks and speeds past Koichi. Do-Ji attacks Riku and says that he wants payback for earlier. Riku blocks the attack and tells Do-Ji that he’s gotten stronger since their last battle. Koichi and Yukki want to help Riku but are unable to, so they leave that to Ayame. Do-Ji cries after Riku knocks him to the ground and holds him at gunpoint. Ogre then arrives and attacks Riku, who manages to hold his own. Do-Ji thinks Ogre will take notice of him if he beats Riku. Ogre sees that Riku has strengthened enough to control Trans-Am, but Riku vows that he will fight without Trans-Am. Ogre activates it for his Gunpla, and Riku stands still and dodges an attack from behind. Riku jumps and is knocked out of the air by Ogre, who charges to attack again. He’s blocked by tail spears from Do-Ji’s Geara Ghirarga, which has taken on a monstrous form due to the use of a Break Decal. Tsukasa calls Ayame and tells her not to interfere because Do-Ji is an important client. Ogre asks Do-Ji how he could do this, and Do-Ji answers that he’s lost control of the Gunpla. Multiple tornadoes form as the result of GBN bugs, and Ogre tells Riku to stay out of this. The Geara Ghirarga’s multiple tails attack Ogre, and Riku slices into them, saying Ogre can’t fight this alone. The damaged tails regenerate, and Riku tells Ogre that they can damage the Geara Ghirarga using a weapon enhanced by a Break Decal. Ogre attacks again, and Riku stabs the Geara Ghirarga’s chest with a piece from one its broken tail spears. The Gunpla finally stops moving, and Ogre tells Riku that Hyakki is withdrawing from the battle, thus giving the victory to the Build Divers by default. Do-Ji cries about wanting to be acknowledged by Ogre, and his teammates explain that they’ve already done that. Ogre tells Riku that he wishes to fight him again someday. Yukki says that even though they won, it doesn’t feel very satisfying. Magee comments that the people spreading Break Decals seem to resent the joy experienced by people who play GBN. Elsewhere, Kyoya meets with Rommel, whose force lost a battle against Mass-Divers.
The Build Divers engage in their second team battle, which lines Riku up in a rematch against Ogre. Riku has definitely improved his Gunpla and battling skills since their first encounter, but we never get to see the outcome of their rematch due to Do-Ji spoiling everything with a Break Decal. By this point, this formula is already old: a battle or some other event happens, and the flow is totally interrupted by some upset loser using a Break Decal in an ultimately futile attempt to show their power. Do-Ji is a pretty pathetic character, but at least Ogre did the honorable thing by forfeiting the match. It was interesting to see a base defense concept referencing Gundam 0080, but we never got to see the full potential of this type of battle, again due to having a Mass-Diver involved.
