Our story begins in the world of humans, specifically in the year 2055, a time when humanity has reached the pinnacle of technological advancement—progress so immense it borders on terrifying.
Yet, despite this, humans continue to live in peace, free from wars and conflicts. Life has become easier, with comfort and convenience now woven into everyday living thanks to technological advancements.
However, far away from all of this, on an isolated island hidden from the world, lies the secret headquarters of one of the most mysterious organizations known as Castle.
This organization gathers a group of scientists who were abandoned due to their radical and "crazy" ideas. Despite their rejection, these scientists found a new purpose when a mysterious wealthy benefactor appeared.
This benefactor was not just a financier but a visionary who invested vast resources to achieve a seemingly impossible dream: building a time-travel machine.
