In search of finding the Black Key, Gen and Beni have been planning another twist in the Tenkai Knights normal lives. One day, after school, we see the four boys leaving school, until Beni is in front of their path. Guren recognizes the pink-haired girl, but Ceylan is more cautious than usual and warns Guren she's somehow a threat. Despite his friends words, Guren's curiousity got the better of him. Which then gives Beni the chance to trick all four boys. Walking to the docks, Beni then lead of four Knights into an abandoned warehouse. Once there, all the boys came to a realization it wasn't a great idea to be at the place when Beni starts talking about unknown information. Finally, Beni then stalked off, to open a portal that lead our heroes to Quarton. On Quarton, Guren and his friends were the Tenkai Knights and regretted trusting Beni. This is when they meet Urius, the Guardian that is color coded as the color red. The Guardian then tests Bravenwolf, Tributon, Lydendor and Valorn as Venetta watches them struggle to fight the clones of themselves. Meanwhile, Gen is watching the fight the entire time. He then starts to ponder over Guren's actions and strengths, which he used to have at a younger age. This lead to a flashback of him playing basketball and smiling, but it soon fades away as Guren entered his thoughts.
