Kingdom Hearts: Catch Your Fate

As the barriers between worlds are slowly eroded, and human history is being compromised, it's up to the Sky, a Sword and a Cherry Blossom to save their worlds and their loved ones, but will they be able to save humanity's future? Or perhaps mankind would be better if they faded away into 「　」? (Reboot of Tsubasa Hearts: Crossed Fate and Chaos). Nasuverse/KH/CLAMP crossover.
