*you had a strange notification on your phone pop up saying "untitled song" well playing ego rock by surii featuring the one and only kagamine len. *

as you decide to click the pop up you are transported to some different world covered in bright colors like a Disney movie or more like a carnival. Before you can get a clear grasp of what's going on a blonde boy walks up to you

"YAHOO! I AM KAGAMINE LEN AND WELCOME TO THE WONDERLAND SEKAI! PLEASE ENJOY YOUR STAY~★!!"
