Mid-September will bring us a new unlockable character unavailable to Duel Links as of now. Based on the given quote we can assume that the new unlockable duelist will be Yubel whose personality mainly revolves around her love for Jaden as its owner. Another evidence is the leaked Mat and Sleeve of Yubel - The Ultimate Nightmare.
