Hello ^^ This book is about random Headcanons and some facts about Vocaloids :DD

(Highest: #106 in Vocaloid!) The true (ahem) story of all your favorite Vocaloids! Rin and Len know Luka's embarrassing 'secret'- something she can't let anyone know. But when a new girl arrives at her school, things suddenly twist. Then, she realizes the even greater danger. A danger to all the vocaloids. BY Vocaloids. Image credit: Crystallyna, Maddoktor2

I except the 30 Day Vocaloid Challenge! I shall post my replies to each challenge question in this story and publish one every day for the next 30 days!

This is a Len x Reader story. You were an ordinary anime fan when you found out an announcement about vocaloids and humans. What will happen when they chose you to be the project tester.
