Episode 1 - "Two Worlds" / The Hero, Braven Appears!

Guren Nash moves to Benham City with his father, a very busy man, who often has to move to other cities due to his work. At his new school, he is peeved by his new classmate Ceylan Jones. After school they enter into talks and even call them dudes and go through the city. They stop at the mysterious "Shop of Wonders" owned by Mr. White, which didn't have customers for one month. The owner shows them two mysterious items, one of them Guren turns into a robot. Mr. White gives them the robots free of charge. In his room Guren wants to come behind the mystery of the robot, but isn't successful. While sleeping he has a dream, where Vilius and Bravenwolf fight each other and Bravenwolf is defeated. In school he tells Ceylan about this dream and finds out that Ceylan had the same dream. After school they return to the shop, but Mr. White appears to be not there. While searching for him in the basement, they notice that their robots are shining and a big robot begins moving and chases them into a mysterious machine. Guren awakes on Quarton and is now in the armor of Bravenwolf. He can't believe that but his armor's built-in Artificial Intelligence guides him to search Ceylan, who now have become Tributon. They are attacked by an army who serves Vilius. After they get their weapons they defeat the army. At the same time Vilius hears about the return of his enemies, and commands his servants to defeat and capture them. While fleeing another army attack, Guren and Ceylan got outside into the daylight, but the army still follows them. They are defeated by another allied army, who recognizes them as the legendary Tenkai Knights. After that Guren and Ceylan are thrown back to Earth.
