Masumi tries to finally prove himself to Satoru on a mission to prevent Ryuuwon and his most powerful Wicked Dragon from obtaining a power to rule the world.
Sakura informs the others that the Precious from Hermit's Groge has completely be block off. It seems there is a huge Jell-O like dome has been formed around it. Mr. Voice asks about Dark Shadow. Masumi stresses how dangerous Yaiba is. When Natsuki mentions how scary Yaiba is, Morio is reminded to ask Masumi if he cleaned his dorm room already for the new year. Turns out Masumi has completely forgot about it. Everyone else has finished, Satoru had already finished in November. Satoru boasts that an adventurer must always be a step ahead. Shouta asks him to please clean his room, because his room smells so much that his room is starting to smell. A Jaryuu successfully kills 3000 Jaryuu. Ryuuwon plugs a hose to his sword and impales him with it, pouring him with all his science, making the super strong Tagargin. Masumi has piles of garage bags in his black-themed dorm room and wonders what cleaning has to do with being an adventurer. His old diary catches his eyes and he opens up to find the entry about the first episode, where Masumi wanted a duel with Satoru. Masumi throws the diary away. His Acellular rings. All the GoGo Vehicles head in search of another Precious, this one has a hazard level that increases. They are attacked by Ryuuwon and Tagargin. He tells them it is the Three-Headed Dragon of Darkness. It has the power to make a ball of darkness come down from the sky. For the chosen one to receive the power. They transform. Silver goes against Ryuuwon, Yellow, Red, and Black go against Tagargin. Blue and Pink go after the Precious, but Tagargin stops them with a rifle he makes from his arm. Red says to take care of the monster, more than the Precious, they all agree and fight against it. Ryuuwon wants Red to be defeated. Pink and Blue go after Tagargin with their Survibusters. Yellow then performs her 'Scooper Phantom' attack on Tagargin, he turns his rifle arm into a replica of her Scoopers. He sends a similar attack on them all. Blue does an attack with his Knuckle Cannon. Tagargin explodes and rises from it using a tornado. He has copied his weapon. Blue wants to use the Dual Crusher. Pink is against it. Black then decides he is his opponent and fights against Tagargin. Meanwhile, Ryuuwon tells Silver he isn't an opponent for him. Tagargin makes his arm into a copy of the Survi Buster. Black is knocked down and gets up again. Yellow tries to stop him. Red tells her to wait. Black conducts his Hammer Break and while Tagargin makes a copy of the hammer, Red shoots him with the Dual Crasher. Tagargin retreats. Satoru offers to help Black up but he refuses, stands and un-transforms. The others gather and ask Masumi why he was being so reckless. He doesn't answer. Akashi explains the last attack worked because since Tagargin's nerves focused on forming a weapon, making it his weak spot. Masumi is insulted because he did all the work. Everyone rushes off, Masumi follows. Ryuuwon blows Silver down the hill and goes after the Precious and it flies out of its palace. It glows and Yaiba stands up in an unknown location. He says the time has come. The Precious buries into the ground. Eiji witnesses this. Ryuuwon then retreats. Eiji is about to go after him when the others arrive and he is a bit peeved. He explains the Precious left on its own and this shocks the others. Meanwhile, Ryuuwon and Tagargin are gathered elsewhere. Tagargin says Red won't get another chance to do damage, he won't let the experience go to waste. Tagargin brings down one of his tendrils down into the ground to track the Precious. Meanwhile Eiji is tracking it with his SagaSniper, hooked up to Shouta's laptop. Satoru says if an attack was doubled and returned, even the Aceeltector couldn't be able to block it. Natsuki asks Masumi what is up. Masumi stands up and tells Satoru he will defeat Tagargin and not to get involved. Satoru thinks he is saying this because he didn't like him using him like he did. Masumi is sure he will defeat Tagargin. Satoru thinks it is something deeper. Masumi admits it is a duel between them. In beating him, it will be beating Satoru. Sakura is outraged. Natsuki says it is meaningless. Satoru accepts his duel, which shocks the two women. Satoru says a method of high motivation is best to defeat the foe and collect the Precious. Shouta gets in between of two, before it gets heated. He has found the Precious' location. Before the Jaryuu go retrieve it behind a waterfall, the Boukenger block the way. They transform and present themselves. Black says his opponent Tagargin and Red says he will stay to watch the results. Red leaves Ryuuwon to Pink. They all start fighting. When Tagargin forms his hammer, he hits Black's Acelltector that he calls at that moment. He performs 'Hammer Dynamite' attack and it doesn't arm Tagargin, he predicted the attack. He beats up Black into Masumi. He is about to bash him, when Red shoots Tagargin's hammer. Red jumps down and fights him with his Survibuster. Masumi is convinced the blade won't work. Tagargin makes his copy hammer and finds Acelltector once again. Both Tagargin and Masumi tell Red it won't work. Red drives his Survibuster into Tagargin's chest and pushes and pushes it in and finally impales him right through. Masumi is shocked. Red then slashes him with his Golden Sword and he blows up. Masumi has a bloody lip. Masumi stands asks how he could do it, since he did the same attack he did. He explains it is feelings, that if both fighters honed their techniques and got to the highest levels and clashed, there is no result because there is no difference between the two. Satoru says in that specific case, the deciding factor is feeling, the desire to defeat your opponent no matter what. Masumi crashes to his knees and bashes the ground with his right fist. He says Satoru is always a step ahead of him. He wonders if he could ever surpass him. The energy of the monster than gathers and becomes huge. Satoru covers Masumi, who is lost in thought as the monster shoots fire down at them. Ryuuwon then brings the other four down. The monster appears near them and blows fire at them, at Ryuuwon's command. The monster is about to hit again, when Zuuban hits him. Red comes in and attacks Ryuuwon. He orders Silver to go. The monster is about to shoot Zuuban with his rifle when SirenBuilder blocks the attack. They fight against the monster as the others fight Ryuuwon. The Precious comes bursting from the waterfall and Ryuuwon is about to catch it, when Black leaps into the way and grabs it. SirenBuilder has attacked the GoGo Crane to it off screen. SirenBuilder Crane then wraps its hook around the monster, swings and punches the monster at close range. Zuuban destroys the monster with his finisher kicking attack. Meanwhile, Red attacks Ryuuwon with his finisher. Each pair of eyes of the Three-Headed Dragon of Darkness glows. a black smoke surrounds Bouken Black and it un-transforms him back into Masumi. Ryuuwon, who is beaten, turns around as the others move forward, shocked. Elsewhere in a bamboo forest, Yaiba's hunch is confirmed. He says Masumi's darkness is still within him.
