Ressha Sentai ToQger

And What Do We Call You? (1x18)

:

At Castle Terminal, Emperor Z confronts General Schwarz about Zaramu with an interest in the former Shadow Line member. However, he reveals he knows he is acting behind his back, and warns General Schwarz to cease unauthorized activities. On the Ressha, though he has given back the AppliChanger and his powers have finally faded away, the topic of letting Zaramu join the ToQgers is brought into question before they arrive at Henzutsū Dark Station where the Shadow Creep Ring Shadow is torturing people with his headbands. The ToQgers find Zaramu with Ring Shadow and see him get a headband, but he is immune to Ring Shadow's ability as he has long since discarded his name. However, Emperor Z arrives and revives Zaramu's nature as a creature of darkness as he and Right are both subjected to Ring Shadow's power. Emperor Z tells Zaramu to meet him again to continue discussion with Right as incentive. Though Hikari refuses to trust him completely, Zaramu promises to save Right and find a place where he can die. Back on the Ressha, the gang debates on what to do before Hikari gets an idea. Later, Zaramu arrives to where Emperor Z is waiting as he proceeds to torture Zaramu to find how he has opened his heart to the light. After Right tricks Ring Shadow to remove the headband, the other ToQgers arrive as they use the Rainbow Rush to give Zaramu a new name: Akira Nijino. Emperor Z gets his answer upon seeing the rainbow, and, dejected by his inability to be accepted by the light, leaves Ring Shadow to deal with the ToQgers with Akira allowed to fight alongside them as ToQ 6gou. After being defeated by ToQ 6gou, Ring Shadow overpowers ToQ-Oh before ToQ 6gou summons the Drill Ressha which combines with ToQ-Oh to form ToQ-Oh Drill to destroy the Shadow Creep. With everything back to normal, save for his ideal, Akira turns down the ToQgers' offer to join them aboard the Ressha as he walks off to protect the Rainbow Line in his own way.
