Kingdom Hearts 3 X Fate/ Grand Order
After using the Power of Waking one final time in order to save Kairi, Sora wakes up in a city called Shibuya wet and alone, just in time to be found by Romani Archaman and Olga Marie Animusphere, who just so happen to need one last Master canidate for the First Grand Order.
Their fated meeting has such far reaching consequences that even Xehanort himself is left speechless by them, and Alaya is left wondering if killing off Ritsuka Fujimaru so early in the timeline was really the correct decision after all.
