ATID-515 I thought she was clean, but who would've thought she was such a bitch. Hikari Ninomiya.

When I became a college student, I was thinking of joining a circle to live the campus life I longed for. Which circle should I join... When I was wandering around the school, I was called out to Hikari-chan and decided to enter the intercollegiate circle where she was. I fell in love with her at first sight because of her neatness. And miraculously, we were able to get along. I wondered how fun my college life would be from now on...I was filled with anticipation. But... I saw something I shouldn't have seen after this.
