INDIGO ; Stray Kids

120 years ago, half of the remaining earth population took a spaceship to escape the planet and save themselves. The other half stayed down on earth, awaiting the moment the planet would be suit once again to be the home of the whole human race.

Under intricate labyrinths and complicated special see-through carbonated glass, the population on Arcanum looks up every single day, hoping for the moment they can be reunited with their loved ones.

Until Indigo, the spaceship, sends an emergency call. Something is wrong. Something is really, really wrong.
