Tenkai Knights

Guren is a new student in Benham City. He 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 dreams about Vilius and Bravenwolf's fight where Bravenwolf is defeated, a dream that Ceylon also shares.

After their first trip to Quarton, Mr. White and The Guardian fill them in on Quarton's history. Ceylan refuses to return to Quarton, but Guren insists they've been summoned to protect both worlds from destruction. During a visit to the museum, the two boys see an ancient stone tablet that later turns into a key in front of them.

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.

A mysterious new student arrives in Brandom City while on Quarton, Tributon fights to achieve Tenkai Titan mode. In the end, the Tenkai Knights face the appearance of Dromus, an evil clone of Bravenwolf who takes the fourth Dragon Cube with him.

Chooki has always been good at sports, school, and, well, everything. But in order to save Toxsa, Chooki gets himself jinxed and becomes clumsy and unable to do what he's best at. The four travel back to Quarton, where Chooki unlocks his Titan Mode while overcoming the jinx.

Commander Beag sacrifices himself to save the Tenkai Knights from falling down, causing them to develop a new Robofusion. They soon find out Beag is trapped in the Valley of Secrets and go to rescue him. They also find the fifth and last Dragon Cube inside the Valley.

Jealous of his teammates all being able to achieve Titan Mode, Toxsa travels to Quarton to train in secret. Meanwhile, Vilius sends out an attack and Toxsa is captured. The other Tenkai knights travel to Quarton to save Toxsa. After realizing he needs his friends, he goes Titan and forces Vilius' forces to retreat.

On Earth, Guren receives Gen's advice about "choosing the side he wants". Meanwhile, the Corekai decide to infiltrate into the Dark Fortress to find the last Dragon Cube. But Dromus is equipped with a Core Corrupter to make the Corekai evil. Remembering Gen's advice, the Knights are able to turn their allies back to their old selves, causing Dromus to retreat.

The gang splits into two groups, Guren and Chooki try to find a clue about the White Dragon Key. They find a sign which takes them to another and another (at one of these signs they spot Gen). They finally arrive at the Key and have to go through booby traps. Guren finally gets through and takes the key. Meanwhile Toxsa and Ceylan are fighting such a hard battle they have to go Titan mode.

Following the battle located in the Dragon's Nest, Guren and Chooki travel to Quarton with Boreas, where the five Cubes are combined into one giant cube that can be only opened with the Dragon Key, awakening the Tenkai Dragon. However, Dromus captures it in a trap and transports it to the Corrupted headquarters.

Beni and Gen scheme on Earth for a way to distract Guren from the other boys. On Quarton, a new villain named Venetta is revealed.

Ceylan's self-doubt leads him to wonder what skills he brings to the team. Is he the best Tenkai Knight he can be?

On Earth, Mr. White takes the boys fishing. Everybody catches a fish, except Chooki. He takes this pretty bad and wants to keep trying until he catches one. Meanwhile on Quarton, Vilius and the Corrupted can finally withdraw the Tenkai Dragon's energy. Granox, Slyger, a corrupted soldier named Shadius, and a Sho can robofuse as well.

Beni tricks the Knights to travel to Quarton into a trap. Another Guardian named Eurus appears to be helping her and Gen to keep balance because Boreas is helping the Knights.
