Join Miku, Luka, Gumi, and the rest of the Vocaloid cast as they embark on an adventure of epic proportions!

What's going to happen when Luka signs up for a job to escort a rich and spoiled princess? Well she's definitely going to change her definition of an escort that's for sure. M for fighting and some cussing.

Megurine Luka and Hatsune Miku are childhood friends, but Luka has to move away. Luka promises to return and does so six years later, but what will she find waiting for her? Will Miku still be there, and most importantly, will Miku still be the same Miku?

Part II: "Not only is this a day of celebration, but the beginning of a new age. Consider this the turning point to a new dawn, the sunrise after a long and dark night. I stand here before you today bearing a demon child! They will bring about the end of the world, but we shall stop them, we, we, shall make the un-killable, dead at last!"

The blade flew into the young girl's skull, killing her. But out of the fog of pain the small child staggered to her feet and pulled the blade right out of her head, splattering the audience with blood. "Such a bad child you are! Demon child!" And without another glimpse of daylight she was shut away. But that was a long time ago. And things change, but not that much.
