How? It just dropped you in with the Statue of Liberty guy suddenly revived, then he sends out monsters, who Red starts fighting for what seems like no real reason other than being wacky, and then Torin comes from the sky and says "time for you to be a Kyoryuger". Then it cuts to a montage of the other guys, who are all of a sudden Kyoryugers (even though the enemies have just revived). Then Daigo's tossed into the restaurant, after which we have a fight scene. I don't remember any real explanation in terms of what I'd been thrown into.

Though I normally hate to side with Sentai on these things, I think you need to watch the episode more closely. Most of what you're asking about was explained, if only briefly. We don't know the particular reason why the Debos have resurrected aside from them falling out of the ice which had kept them imprisoned. But Torin does say that Daigo is the last member of the Kyoryugers to be chosen. Recall that Daigo is fighting Gabutyra for a full month before he gets off the island. The others have been fighting while he tried to beat Gabu.

Torin himself says The Frozen Castle has fallen. And Daigo is fighting to save the people of that village, the ones running away very scared? Those people. Candelira is The Soldier of Joy. She embodies the Emotion Joy and uses it when she fights. As for "Statue of Liberty": Chaos explains that their trying to thaw the Heart of their Master. Deboss. And exterminate the dominant species of the world. Millions of years ago it was Dinosaurs, now it's Humanity. And the monster he throws at them first, Debo IceAge, is the monster that did it.

Between Torin and Chaos they pretty much explain the whole plot. So.. I don't understand why you don't understand. (Warned you I love this more than Goseiger, I did!)

Holy shit. Sound logic and discussion from Sentai :lol

Be Afraid >D

Call it my fault in that case. My guess it that it's just a little more blink-and-you-miss-it because it's the first episode, then.

The episode does move a little fast.

Not to rain on anybody's parade, but does pointing out plot points explained in series qualify as logic?

From me? Yes!

So Sentai loves Kyoryuger more than Goseiger?

TENSOU!

If you need me, I will be on KO-35 while Earth begins to implode from that revelation.

And on a more topical note: I love the Samba. It makes me happy for some reason.
Vamola, 2013! Todo mundo SAMBA!!!!
