The Tales of Graces official site has been updated today with three new character videos, the first videos for Sophie and Hubert Ozwell and the second video for Malik Caesars. Downloads for the videos are available at AC's ToG Video Section. They can also be viewed in their individual character pages.
The official site's System section has also been updated today with explanations on Chain Capacity (CC), Around Step and Character Change in battles. The screenshots and info are old though. You can read about the game's system here.
