Seven years ago, Lopplc and Morina were playing at a park. Suddenly they felt an earthquake on the Koya Koya Planet. The quake was so massive that the planet was destroyed. Everyone had to escape using a giant ship. A sudden bolt of lightning damaged the ship, causing a power failure. The Professor (who was Morina's father) wanted to fix the spaceship, but another lightning strike took him to another dimension.
