Prior to the days of Perfect Harem Anime for Topaz and Zettai they both decided to write for the other. They still write using these characters, though in a more restricted format. The name of this series is "Imouto no Ecchi na Oshiri" (shortened to 妹尻, "ImoShiri").

These are Zettai's characters. If you would like to see Topaz's, click here.
