It's a week before her birthday and Hikari should be overjoyed, but the creatures of the dark world have begun to move once again. This time, however, they're opposed by a stranger from afar, an inexplicable digimon who seems to fight clad in darkness. Will the chosen children recognize him as a friend? And what will he see in this new world? A 02xFrontier fic.

The only thing worse for Ruki than being dragged out to some boring little town is being dragged out there to spend time with family members she barely knows. But there's a mystery afoot when it turns out a whole host of Digimon living in town under the command of the mysterious and powerful "Sea King". And Ruki is going to find him. Maybe this vacation won't be so bad after all.
