Obviously Same

"... Exactly the same..."
"Something wrong with me?"
"You look almost exactly the same with me."
"Isn't it obvious? We both are basically the same product. Only differ in version."
"I wonder how Master will differ between us."
"Ask Master yourself then, rather than keep staring at me. He installed both of us."

Playing around with some other theme
And yes, i am quite a fan of Vocaloid and Kagamine Len is my fav.
