Yes, I'm about to give you some vague spoilers for the first hour of Bravely Second, just in case you were wondering.
Right off the bat, newly anointed Pope Agnès is kidnapped by the Kaiser, and her loyal knight Yew Geneolgia sets off to rescue her. He's accompanied by his friends Janne Angard and Nikolai Nikolanikov.
And then it all goes so, so terribly wrong. Skip ahead to 36 minutes in to catch the moment where it all falls apart.
Bravely Second owes its combat system to Bravely Default. You can "default" a turn in combat to build up brave points. You can spend the points to attack multiple times on a turn when you choose the "brave" option instead.
Bravely Second comes out on April 15 for the Nintendo 3DS. There's a very fancy Collector's Edition that comes with a 250-page art book, if that's the kind of thing you're into. You can pick up the regular version on the eShop for $39.99.
