Danko Shikihen: Tora wo Danjite Iro Henzu

Naruo Yurie, a student of calligraphy who can see "black figures" that are not human, has been involved in mysterious incidents since the day he met the landlord of the house where he lives in Tokyo... This is a story of love and longing between a divine beast and a human.
