The group is in a deep sleep, and it's time for them to wake up. They don't know why they're in such a deep slumber, but they do know that their mission is to fight the monsters. They can't just wake up by themselves, though, because they'll need someone to wake them up before the seal is gone. They're called "Guardians" because they wake up the people who live in the relics they've collected. So, the guys need to find out what's going on.
