Roughly a hundred years ago, a catastrophe known as the Ruina (The Great Collapse) destroyed civilization, and the sun stopped rising. This is the World of Endless Night.
Across the land lie the ruins of fallen cities and the remnants of an old civilization, while beautiful blue and purple auroras shimmer across the sky. But that light is also a sign of danger—born of an unknown energy called Lux.
Investigating the Lux anomalies erupting across the world, three girls—Reina, Mirea, and Luluka—journey among the ruins of the old civilization, drawing ever closer to the truth hidden behind the Great Collapse and the auroras.
What awaits them is the Watchers of the Dawn, who reject any change to the world, and their leader, Nox.
Will they protect a present that is doomed to fade? Or will they risk everything to reach a morning no one has ever seen?
This is the story of girls living in an endless night, choosing their own future by their own will.
RUINA is a single-player game that combines visual novel-style storytelling with command-based battles.
As battles occur throughout the story, you can choose which of the three protagonists—Reina, Mirea, or Luluka—to fight with.
Choose your commands, make use of each character's unique traits, and anticipate your opponent's actions to claim victory.
In addition to the main story, RUINA includes a Free Battle mode where you can enjoy battles separately from the story. After completing the main story, you can continue fighting with your favorite character.
