You Keika, the last living member of a once prestigious exorcist family, inks out a living as a fortune teller and computer repairman. One day, he witnesses a silver-haired man fighting with an evil spirit. Bewildered by the unrealistic sight, Keika is unable to stay in hiding. On his way home after this encounter, Keika loses his life in a fatal accident and finds himself face to face with the mysterious man from earlier that evening. Calling himself, Tanmoku Ki, the man requests that Keika become his "spirit shadow". Keika initially refuses this request but finds himself pulled into Tanmoku's fight with the little girl spirit...
Hmph, like a good kid like me 
would become an evil spirit.
محال أن يصبح صبيًّا صالحًا مثلي روحًا شرّيرة
¿Que un niño bueno como yo
acabará como un espectro?
¿Que un niño bueno como yo
acabará siendo un espectro?
Mah! Come se un bravo ragazzo come me
potesse diventare malvagio.
Puxa, um bom garoto como eu 
me tornar um espírito maligno?
