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 I can get my hands on that power, 
I will become invincible and
،إن استطعتُ اكتساب قوّته تلك
فسأصبح منيعةً وقد أُخلق من جديد بهذا العالم
Wenn ich diese Kraft besitze,
werde ich auf dieser Welt unbesiegbar sein
Si obtengo dicho poder,
me volveré invencible,
Si obtengo dicho poder,
me volveré invencible
Si on s’appropriait sa puissance,
on serait invincibles
Se riuscissi a impadronirmene,
diventerei invincibile
Se eu conseguir colocar as minhas mãos
 nesse poder, eu me tornarei invencível
