Update: Tweet has been updated to the original source of the scan.

A new screenshot of a Bravely Second scan from Jump magazine teases a very interesting image of who looks to be Tiz, the protagonist from the first title (thanks to Kazu for the tweet):

Bravely Second2

His design is completely different from his simpler farm-boy design from Bravely Default; here he looks much fiercer, almost evil looking. He's still a hero, however, due mainly to the existence of the special video at the end of the first title.

Speaking of that, the scan indicates that you must rescue the imprisoned hero Tiz, which means the special video is a part of the actualy plotline, not between the two games.

Finally, there seems to be a new job called "Guardian," as well as a new system.
