Shinju Inui

Unlike her sister, who is rather blunt and headstrong, Shinju is a timid yet kind-hearted girl. She is shown to get nervous easily, especially when meeting new people, as seen during her first meeting with Gojo and Marin. This aside, Shinju strongly admires and loves her sister.

Shinju is aware of her mature figure, particularly her chest, and is shown to get embarrassed about it. She also calls herself "fat" in the Japanese dub of the anime. Besides her huge tits 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 proven to be a hurdle in achieving this.
