My Abnormal Little Sister and Me, Imprisoned

While I was secretly filming, I ran into my younger sister, whom I hadn't seen in a long time and who was acting extremely strangely. I never imagined that this would lead me into an incredible world, or that I would end up imprisoned by a girl who couldn't hurt a fly.

She was the warden, and I was the prisoner.

A work in which the author lets loose. First-person narration, irregular updates, and an attempt to imitate Nishio's rambling style. Don't get your hopes up too much.
