The Build Divers are given their first monthly Battle-Random mission, and their opponents are Hyakki, led by Ogre. Despite Yukki's doubts about a rematch with Ogre, Riku proceeds with the mission to test all of the skills the Force has learned from their first encounter with Ogre. However, Riku insists on keeping his promise to Sarah to not use Trans-Am. During the battle, Do-ji deviates from Hyakki's strategy and charges towards Riku, only to be defeated in hand-to-hand combat. Ogre arrives to challenge Riku, but Do-ji activates Break Decal on his Geara Ghirarga and interferes with the duel, much to Ogre's dismay...
