In a developer diary for Soulcalibur VI, producer Motohiro Okubo explains what makes this reboot version of Sophitia so special.
Okubo kind of frames Sophitia as Soulcalibur's Ryu, making her a good character for novices who fights with an orthodox style. Okubo noted that Sophitia and Mitsurugi were the first characters made for the game and every other character was built around their style and visuals.
Check out the developer diary below. Soulcalibur VI is scheduled for PlayStation 4, Xbox One, and PC in 2018.
