When Rin Kagamine's brother reappears after two years as mysteriously as he disappeared, Miku Hatsune's life begins to get a little crazier as she takes an interest in Rin's brother, Len. As she slowly unravels his perilous secrets, not only does she learn more about herself, but she also realizes little too late that some things are better off staying buried and forgotten.

Len Kagamine never meant for the fiery tealette named Miku Hatsune to get involved with his 'secret' life. But after Miku is forcefully, violently, and suddenly thrown into Len's world, he has no choice but to spill. Now with Miku knowing about the horrific deeds that the Kagamine has both done and witnessed, she's officially beyond the point of no return. And it was all Len's fault. Sequel to Hardened. If you haven't read Hardened, please do so before reading this or you'll probably be super confused. Thanks~~~
