Determined

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~~~
