Plot
On Earth, Gen watches as people in Benham City enjoy a pleasant day in the city, all the while thinking about how the peace will soon be shattered and the world destoryed.

At School, Guren notices that Gen is back in class, but still can't understand why he acts so distant. For a moment, Guren thinks that Gen might actually be Dromus. When Guren asks Ceylan what he thinks, Ceylan simply walks over to Gen to try and make friends. Ceylan gets scolded at by Gen for his troubles.

Later, Gen, as Dromus, reports to Vilius that he's continuing in his attempts to find the Black Key. Vilius warns Dromus that he expects results and sends Dromus away. Later, Vilius confides in Slyger and Granox what he knows about Earth, and his intentions to invade.

On Earth, Ceylan is angry about what happened with him and Gen. When Guren asks him why he reached out to Gen, Ceylan answers that Gen reminded him of Guren.

Back on Quarton, the Tenkai Knights must find a way to transform into Titan Fusion before they are destroyed by a rampaging bull-like creature. Tributon comes up a plan to hid under the bull so that it can't attack them while they transform. Once transformed into Fusion Mode, they easily dispatch the beast, all while Dromus seeks to find a weak link among them with his sights now set on Lydendor.
