Erica Kuramoto, Yui Nitta, Misa Suzuhara and Kotone Sasaki look like ordinary schoolgirls, but each of them holds supernatural powers. They use those abilities to shield everyday people from invading alien creatures. The single-episode OVA mixes magical girl action with romance and heavy ecchi content, and it adapts an adult manga by Raita. It is a self-published doujinshi production, released on Blu-ray Disc at Comic Market 82 in August 2012.
