'Protect it at all costs. Even if it means death.' This is the objective of every human who lives on Earth in the year 3015. But that was different for Dion. In a world where only powerful entities rule and the weak have to abide by their so-called 'laws,' it isn't really different from a prison world. In this new era of magic, where unimaginable powers are cultivated and used, there is only one goal Dion knows and follows: 'Protect my loved ones at all costs... even if it means death.' In 3015, the 'Invaders' arrived at Earth intending to wipe Earth's creatures off the planet, including humans themselves. Dion has no choice but to face the adversity head-on while swearing to protect the two people left for him in this cruel universe.
