Rin is a very energetic, positive, and childish girl that likes to tease others and pull pranks, especially on her "twin brother" Len, but she doesn't mean any harm with it. Yet, she has a kind heart, but is somewhat tsundere. Also a bit stubborn. She is very fond of oranges, loving them very much. Rin has short blonde hair that goes to her chin, with bangs that are held back by small white clips and a headset with a white bow on top.
