This was a prelude to Maki Murakami's Gravitation, but is not considered to be a part of the series. Many of the characters look similar to her Gravitation cast. This comic is the original story by Murakami, which was later rewritten somewhat into the series Gravitation. Rather than starring Shuichi and Yuki, the stories star Sakuma Ryuichi--lead singer of the band Nettle Grasper--and Uesugi Tatsuha as a novelist in a romance fairly similar to the one in Gravitation.

Tanemura is just a regular high school boy, but when he is assaulted by demons, he is saved by a girl in his same school, Tateeboshi Suzuka. She is a very mysterious girl and no one really knows much about her except for the fact that she is referred to as the shadowy master. Tanemura finds out that she is in fact an exorcist and has been eliminating the demons that plague the town he lives in. The more Tanemura gets involved with Teteeboshi, the more dangerous demons he encounters.
