Promise

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!
