Shikkoku no Bojou

Cram school teacher Toshihiko Katayama is strikingly handsome and thoroughly accustomed to being the focus of any room. Then a woman with long black hair begins shadowing him, turning her attention on his students and colleagues while inexplicable phenomena start closing in around him. With nowhere else to turn, Toshihiko approaches an old schoolmate, Rumi Sasaki, whose company handles cases of the paranormal.
