The OVA adaptation Nozoki Ana is based on Wakoh Honna's ecchi manga also known as No-Zo-Ki-A-Na (or A Peephole). The manga's limited edition 13th and final volume bundles the OVA on DVD. The story centers around Tatsuhiko Kido, a young man who moves from the countryside to Tokyo to attend a vocational school in the spring. He discovers a tiny hole in a wall of his new room, and although he looks in from time to time, he sees nothing at first. However, one day, he spies a girl. (based on ANN synopsis)
