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...
If she remained here, the balance between 
light and shadow would crumble.
إن ظلّت هنا، فسيختلّ التوازن بين الضوء والظل
Wenn man sich dagegen sträubt,
gerät die Balance aus dem Gleichgewicht.
Su estadía habría roto
el equilibro de la luz y la oscuridad.
Al quedarse aquí habría roto
el equilibro de la luz y la oscuridad.
Sa présence menaçait l’équilibre
entre l’ombre et la lumière.
Se fosse rimasta qui, l'equilibrio
fra luce e ombra si sarebbe sgretolato.
Se ela continuasse aqui, o equilíbrio
 entre a luz e a sombra sofreria.
