Due to an accident, Len Kagamine fell into a time gate that led him to the future of 40 years later, the year 2060. Since then, his life had been involved with the future world, Rin Kagamine, and the mystery she always wanted to find out.

Rin Kagami - a loner, a social misfit who just loves drawing, is searching for a certain person that can be her inspiration. Why is Len Kagamine, the popular boy of the school suddenly so willing to become her model, she will never know, but this surely leads to a lot of past revealing, love, and secrets.

Len is one of the best UTAUloid hunters who just dates about every female hunter in the area. And Rin is just a new comer that doesn't remember anything from her past. Will the cold-hearted playboy Len Kagamine set his heart on Rin? And will Rin be able to get back her memory and discover who she actually is? Oops. I'm really bad at writing summary, please read and find out.

Kagamine Rin and Kagamine Len were twins. Then tragedy struck.
