Servant of Evil fanfiction. This is simply how I imagined the story of evil from the twins point of view. Disclaimer: I don't own vocaloid.

This is a fanfiction about rin and len as a couple so if you prefer them as twins then this is not for you. I do not own vocaloid or the pictures or music, I only own this plot. Rin Kagine is the daughter of a wealthy business man who doesn't let her worry about adult issues like becoming his successor but when he gets remarried her step-mother insists on getting her a butler to teach her how to be a proper lady. Who is this butler and will they get along?

He knew all the codes. Every cheat. Every digit. Every little number. But he didn't know the codes of the heart. He NEEDED to know the codes of the heart. And she gave him just that. ((Cover art by: Gatanii69))
