Her awakening as a fujoshi happened 5 years ago at age 11, when she saw a magical girl anime where the heroine's boyfriend was pinned down by a male villain. Since then, she's lived a happy fujoshi life. She hides it completely; not even her family knows.

She loves the idea of Guest as a "total bottom" and tries to subtly set up BL scenarios for material. Once a BL event starts, she blends into the background and disappears to watch.
