Rin is one of the two twin virtual singers of the Serenity SEKAI. She's the first of the two Kagamines, before Len, and is the more cheery and free-willed one of the two. She takes care of the MORE MORE JUMP! group and was programmed alongside Len as Miku's assistant. Despite this, she dislikes the murderous behind-the-scenes of the Happiness and Peace of Mind Committee.
