Promise is the twenty-fifth and final episode of Gundam Build Fighters.

Synopsis

After many ups and downs, the finals of the Gunpla Battle Championship World Tournament are over at last. However, in its aftermath, the Plavsky particle crystals have gone out of control. The particles that fill the arena are starting to materialize, as the panicking audience members rush to escape. The only way to resolve the situation is to destroy the crystals. On Nils's advice, Sei and Reiji dispatch their Gunpla, as do Mao, Fellini, China, and Aila, but they are hard-pressed by the counterattack from the crystals. Their former rivals hurry to their aid, as do the former Gunpla fighters Mr. Ral, Takeshi, and Master Chinan. Let's do it! This is Gunpla's last shooting!

Plot

Around the building, crystalline growths of Plavsky particles erupt along the walls and support beams, threatening to collapse the entire building. Takeshi Iori and Mr. Ral take it upon themselves to begin an evacuation of the audience, assisted by others such as Luang Dallara and Greco Logan. The Gunpla Battle System activates, turning the interior of the arena into a space zone and materializing a representation of Zeon's final fortress, A Baoa Qu.

Even at 1/144 scale, the asteroid fortress is large enough to break through the dome of the tournament stadium. The gathered Gundam Fighters decided to evacuate, while Chairman Mashita comes clean to Reiji, confessing his crimes and begging for his help.

Before the others can run, Nils Nielsen and Caroline Yajima arrive. Nils explains about the giant Plavsky crystal and decides that before the now-unpredictable particle system can cause any more damage, he'll try to destroy the crystal. Unfortunately, the crystal has transported itself inside A Baoa Qu, and the only way to reach it at hand is to use the system against itself and assault the fortress with a Gunpla. Reiji and the other Gundam fighters, even China, Caroline and Kirara, agree to help him. Tatsuya wishes to help, but his Exia is in no condition to fight. Fortunately, Allan Adams arrives with a repair kit. Outside, the evacuation finishes, but Rinko tells Takeshi that the children are still missing.

Back at the Arena, several Mock mobile suits, armed with weapons from across the Gundam saga, have launched from A Baoa Qu in response to the mobile suits approaching. The Gundam Fighters engage in a fierce battle, but there are far too many to punch through... Until Mao deploys his newly-completed Gundam Crossbone Maoh and blows a hole through not only the Mocks' line, but the fortress itself, giving the team a clear path inside. The Star Build Strike, Build Mk. II, Miss Sazabi, and Mr. Bearguy III go into the breach while the others hold off the horde.

The mass of Mocks is endless however and threatens to overwhelm the fighters until Master Chinan and Mr. Ral arrive with their own Gunpla; a Master Gundam and Ral's custom Gouf R35. Together, the two veteran builders show the full strength of their experience, tearing the Mocks apart en masse.

Inside the base, Aila suddenly notices a massive buildup of Plavsky particles as they head towards the fortress' core. The core is protected by a massive particle cannon similar to Requiem or a Colony Laser. The beam fires, with Aila and China just barely managing to push the Star Build Strike and Build Mk. II out of the path of the blast. the massive beam erupts from A Baoa Qu, destroying everything in it's path. Both Miss Sazabi and Mr. Bearguy III are disabled, and more Mocks come pouring through the hole blasted in the fortress, pinning them against the cannon, which is charging for another shot.

Suddenly, Tatsuya Yuki tears through the Mocks with a repaired Exia, followed by Takeshi with a Perfect Gundam. Figuring that the crystal has to be behind the cannon to power it, Takeshi destroys the cannon with a massive blast from the Perfect, giving the Strike and Mk. II an open path. They manage to penetrate to the crystal's chamber, which tries to push them away with a huge wave of plavsky particles. To fight the particle storm, Sei disengages the Mk. II's booster and attaches it to the Star Build Strike, activating the RG system and giving them the power to push through and destroy the crystal.

The shattered crystal exploded, scattering particles everywhere as the Mocks shut down and the space zone and A Baoa Qu fade away. Chairman Mashita begins to glow, as the giant Arista is no longer anchoring him in this world. Baker desperately hugs onto him just as the effect triggers, pulling her to Arian with him. Recognizing the effect as the same one that happened with Reiji before, Sei worriedly turns to Reiji, only to find him perfectly fine.

With the particles disappearing, Reiji wants to have one last battle with Yuuki, without the Embody System getting in the way, while they still have time. Fellini and Mao give the Fenice's arms and the Crossbone Maoh's weapons to re-arm the Build Strike, while Allan hastily re-repairs the Exia with parts from the Kampfer Amazing. As the boys set up their gunplas, Kirara finds a camera and resumes broadcasting herself.

As their battle rages on, Sei thanks Reiji for taking over for his own shortcoming as a Gundam Fighter. Reji assures him that his only fault was worrying too much about damaging the model, and that worry was holding him back. But thanks to the friends and rivals he's met over the course of the tournament, he's learned how to let go of those concerns and be willing to take a risk to earn victory. As his own Arista starts to fail, Reiji lands the Build Strike and turns the controls over to Sei.

Proving Reiji's point, Sei holds his own in battle against Yuuki. But just as he manages to store an opening against him, the last of the particles fade, bringing the battle to an end. Reiji's Arista also gives out, and he begins glowing as well. Sei and Reiji say their goodbyes, with Reiji getting Sei to promise to get stronger so they can fight each other next time. With that, the Arista finally breaks and Reiji disappears.

Later, Reiji stands in the garden of the Royal palace in Arian, promising to see Sei again. To his great surprise, someone hands him his GPB-X80_Beginning_Gundam model. Aila, carried by the Arista passed on from Sei, is kneeling next to him. Reiji is still remarkably clueless as to why Alia would wish to follow him to Arian, much to her annoyance.

A year later, everyone continues their peaceful lives. Kirara's career has taken off, with Fellini happily looking on. Mashita and Baker are selling Mock models in Arian, Nils and Caroline have (re)discovered Plavsky Particles, ensuring that the Gunpla Battle system, still going off previous particle stockpiles, will continue, and Sei prepares to meet Reiji again, defending his title in the 8th Championship with the new Build Strike Cosmos.
