For the grand opening of "G-Quest," Yuuma Kousaka and Minato Sakai are invited to The Gundam Base Tokyo to be its first challengers. G-Quest is a new Gunpla Battle attraction, in which the goal is to clear an event set up by the battle system. Yuuma sets the Gundam Lightning Black Warrior in his GP Base, while Minato chooses the Gundam Dryon III. The time limit is ten minutes! The two of them begin their attempt to break into a secret base protected by countless Gunpla and destroy a new mobile suit that is under construction, before their time runs out.
