Millions of years have passed after the Moon revolution. During that event, Earth and Titan accidentally collided with each other and after millions of years the fragments of the two of them formed a new planet (Terra) and a new moon (Abaddon).

[Note: Terra has no memories of his previous life as Earth. As for Abaddon, he remember everything because he has Titan's memories.]

The moon orbited Mars after Earth died. Today, while passing through Earth's orbit, he saw two new celestial bodies, a new planet and a new moon. A planet that looks a lot like...Earth.

Moon: "What...No way..." In his disbelief, he approached them.
