Ultraman: The Villain's Guide to Self-Cultivation

This story has many parts that don’t quite match the original, so please bear with me! The three Xijia siblings have come to a parallel universe to collect energy. Together with the New Generation members who were also invited here, they find a universe with a pitifully small amount of light, where the will of the universe is using its last reserves of energy to keep everything running. The stars resolve to play the villains in the name of maintaining order in their universe, while gradually repairing the universe on the brink of collapse. Couples: Shizumu, Leo and Seven, Taro and Titas (or Titas and Taro), Gaia and Agul, and many more! Out-of-character warning!
