Through exploration and combat in the game, players will come to understand the importance of energy. They will control the protagonist, Jules (an energy being), to explore and fight, gradually lighting up the environment and restoring the city’s former vitality. This experience will help players appreciate the significance of conserving energy.

The game’s story takes place in Elberus, a city built in space that was once beautiful and highly sought after. However, the energy that powered the city was running out. One day, the protagonist, Jules, received a distress signal from Elberus and decided to embark on a journey to save the planet. Along the way, Jules encountered various corrupted monsters and fought through countless battles until finally reaching the royal castle. There, he met Oternity, the one who had sent the distress signal.

However, Jules soon discovered that Oternity’s true intention was to sacrifice Jules, a member of the Luminous Tribe, in order to restore the planet. At this moment, the player is given a choice:

Accept – Decide to follow Oternity’s plan. The game ends with Jules becoming the new energy core, saving the planet. However, in the distant future, when Jules' energy is depleted, the planet falls into corruption once again...

Resist – Decide to fight against Oternity. Jules refuses to be a mere sacrifice and believes there must be another way to save Elberus. Determined, he embarks on a new journey to find a true solution to the crisis.
