As captured from a Square Enix livestream by Nintendo Everything, the videos show new character Magnolia trekking through what looks like Istantal, going by official images. According to previously released details, it's a city home to a university of magic where the professors helped to develop a "new structure" of the arcane art. As for Magnolia, Bravely Default fans may recognize her from the first game's special epilogue. The site describes her as having a "daredevil attitude" that we're sure Agnes will find unacceptable.
The videos also showcase some of the returning jobs coming to the game, albeit with new looks as shown off by Magnolia. Square Enix only showed the jobs listed on the game's site, namely the Time Mage, Red Mage, Valkyrie and Superstar. That said, if you look closely at the menu around 2:33 in the first video, you'll notice there are 30 different slots for jobs on the right-hand side, compared to 24 in the original game.
According to Gematsu, Bravely Second will be playable at next month's Tokyo Game Show. Maybe Japan's biggest gaming convention will prove the perfect place for Square Enix to finally announce that release date.
