One day, a tiny girl named Shina appeared inside a roll of toilet paper in the Yamaguchi's residence toilet. She made a stunning impression on a typical middle school student, Nobuo.
"What if I use up all of the paper? Would I be able to see her... na... na... naked?!"
It's the beginning of a story about love, lust and... a sh*t ton of other adventures!
