Shinju Inui (乾 心寿) is the younger sister of Sajuna Inui. At first sight you would assume that she is older than her sister, Sajuna who has a rather childlike appearance, but that surprisingly isn't the case. She is, in fact, the youngest out of the two siblings. She has quite a "big" chest and is very tall. Her eyes are a beautiful shade of light brown which compliments her hair that possesses the same color. Besides her huge "personality" and her shy nature, she is also the photographer of the one and only Sajuna Inui AKA the amazing cosplayer who goes by the name "Juju". Like her friends and "big" sister, she is also interested in trying out cosplay but, contrary to the others, she wishes to cosplay as a boy. Her big chest, however, has proved to be a hurdle in achieving this.
