Tenkai Knights

Guren is a new student and meets Ceylan and together they visit the mysterious "Shop of Wonders" owned by Mr. White. Two mysterious items that turn into robots are given to the two teens. Guren has a strange dream, a dream that Ceylon also shares. Later, the robots come alive and the teens suddenly find themselves on the planet Quarton.

After their first trip to Quarton, Ceylan refuses to return to Quarton. During a visit to the museum, the two boys see an ancient stone tablet that later turns into a key in front of them. After this event, they are summoned to go back to Quarton, where they meet Granox and Slyger, two of Vilius' most powerful warriors, while Lydendor and Valorn join the fight, getting the first Dragon Cube.

Guren and Ceylan track down and meet Chooki and Toxsa, the two other Earth boys who possess cores and became Tenkai Knights on Quarton! Their friendship gets off to a bumpy start, but in the end, they all agree on working together to achieve victory after finding the third Dragon Cube.

The boys are starting come together as a team as they learn more about Quarton. While on Quarton - in search of the next Dragon cube - the boys discover that they can combine their Tenkai Knights to become something more powerful, the Prodojet. Back on Earth, the guys learn that someone stole the Key from the museum, possibly for Vilius.

As the four heroes gain confidence after having gained another cube of the Tenkai Dragon, Vilius decides to make his epic presence felt. The Guardian warns the four about the danger of being over-confident, but the boys aren't really listening.

The boys asked Mr. White who manages the Earth side of the portal, an intriguing thrift store, for some Quarton help, but he says he'll only help them if they agree to help him in the store. Believing in Mr. White's procedure, Guren unlocks his Titan Mode for the first time.
