The Murasakibara Siblings

Ren Murasakibara, the twin sister of Yosen's center, Atsushi Murasakibara. But as this may sound, she's not like her brother; Although she has Atsushi's hair and eyes and sweet obsession, she is a 16 year old beautiful/cute girl that is shy, sweet, timid and clingy. These two aren't 'normal' siblings, they have a deep (sibling only!) bond that no one could understand but eachother.
