Long ago, before the universe began, the eternal titan Chronos created a set of 5,555 magical keys. Each of these 'Lost Keys of Chronos' holds the power to change the future, but for centuries, the keys have remained hidden, scattered across both space and time, waiting for the right person to discover them and unlock their potential. Now, with the fate of the world at stake, a new search has begun. Will humanity be able to find them all, unlock their secrets, and save the universe, or will they be lost forever in the depths of time?
