Okino is a serious, duty-bound Samurai warrior who is unaware that Prime Empire is a game, since he is part of it. His job is to lead players through the three dangers of Terra Karana - the Forest of Discontent, the Cliffs of Hysteria and the Maze of the Red Dragon where the first Key-tana is located. Unfortunately, the game is rigged to be nearly impossible and Okino quickly fails his masters, who are dematerialized into cubes of energy. As more and more masters are "cubed", Okino begins to

The Samurai guide, Okino, leads the ninja into the first of Terra Karana's deadly challenges: The Forest of Discontent, made up of deep, dark woods, filled with booby-traps. As the ninja fight their way through it, they begin losing lives, but with Okino's help, they survive and reach the middle of the forest.

The ninja arrive at the Cliffs of Hysteria where they meet Shifty, a merchant who runs a table at the base of the cliffs. Shifty sells the ninja some grappling hooks and rope. Unfortunately, the ninja don't have enough money to buy the "Rope of Supreme Durability" and opt instead for the "Rope of Questionable Integrity". Even worse, as they are buying the rope, they are spotted by one of Unagami's aerial drones. A squadron of Red Visors quickly arrives and pursues the ninja up the cliffs. The

As the ninja and Okino approach the Maze of the Red Dragon, Unagami uses his control over Prime Empire to briefly "pause" all the players except Okino. He appears before Okino, urging Okino to betray the ninja and not help them against the fearsome Red Dragon that awaits the ninja at the heart of the maze.

Having obtained the first Key-tana, the ninja enter the second of Prime Empire's game zones, Terra Technica, where they learn that the second Key-tana can only be won by winning a dangerous race called the Speedway Five-Billion. The ninja realize that they don't have enough game credits to enter the race but earn credits by winning a dance competition.

The ninja appeal to Scott for help in obtaining 5 race cars. Scott shows them his junkyard where he has 5 vehicles that may be repairable in time. Lloyd heads off to the racetrack and watches a live race, hoping to learn as much as he can about the brutal Speedway Five-Billion. One driver in particular impresses Lloyd - a race car driver known as 'Racer Seven'. Lloyd recruits her to help them win the race.

Red Visors discover the location of Scott's garage and Scott sacrifices himself to buy the ninja a chance to escape and they race off.

Cole and Kai bravely sacrifice themselves to buy their teammates a chance to win. With the help of Racer Seven, however, they successfully win the second Key-tana.

Devastated by the loss of Cole and Kai, the surviving ninja push on into Prime Empire's third and final game zone - Terra Domina.

Lloyd is selected and finds himself facing an avatar of Harumi. Lloyd manages to defeat Harumi and wins the third and final Key-tana for the team. Lloyd, however, also loses his final life in the process.

He had not realized how dangerous it was, and tried to shut it down.

The Mechanic's henchmen capture Master Wu and bring him to the Mechanic's warehouse. The Mechanic uses him as leverage to coerce Zane into revealing the location of the motherboard which he requires to open the Manifestation Gate,through which Unagami is to enter the real world. Wu manages to activate a GPS location tracker, which reveals his location to P.I.X.A.L. However, she and Dyer arrive too late. Zane is hooked up to the Manifestation Gate as a type of processor, causing him to pass out

Jay must stand alone against Unagami in the end-game, after Nya loses all her lives, yet Unagami has a bigger battle in facing the truth about his own identity. Jay discovers that Unagami is actually the game and not Milton Dyer. Unagami uses the energy cube from Nya to complete the Manifestation Gate, and travels through it. Jay follows after him.
