In a society where people with monster dominate, high school student Makoto Tatara has a friend in this unusual world. Her name is Toko Meisen. Having a beautiful girl as a friend might make any guy envious... but there’s a twist—she is a ghost, a spirit-like existence! Their bond is one of \"Soul-mates\" (friends who share life energy). To make things even more chaotic, her sense of personal boundaries is completely broken, leading her to naturally do some rather suggestive things! Can Tatara maintain his friendship with Meisen, or will things take an unexpected turn? Note: Depending on audience feedback, this might turn into a full series!
