The stage is set in the Alpha Centauri star system, 4.4 light years from Earth on the unknown planet EXELIO.
A landing pod has just been launched from an exploration ship orbiting the planet, aiming for the ground.
The heat-resistant armor of the landing pod is blackened by the scorching flames caused by friction with the atmosphere, and the intense pressure and heat make the outer shell creak.
The shape of the small capsule, which continued to accelerate as it glided through the launch, looked ominously similar to that of a coffin.
...Amidst the roar, the young explorer Lion lies quietly inside that “coffin”.
He is unconscious and has no way of knowing the impact of the entry or the warning sound, but it is the pod's precise calculating device that controls everything and guides him calmly.
EXELIO - a new place he has arrived at after a long journey.
What awaits him when he awakens from his sleep on this planet?
Is it the promised hope... or an unknown threat?
He will soon be challenged to answer these questions.
His adventure into the unknown is about to begin.
