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...
I wouldn't help when I was alive,
 but I'll be a savior when I am dead.
،لم أقدّم المساعدة عندما كنتُ حيًّا
لكنّي سأكون منقِذًا عندما أموت
Im Leben niemandem geholfen,
aber ein gestorbener Messias …
No pude hacerlo en vida,
pero ahora soy todo un santo.
No pude hacerlo en vida,
pero ahora soy todo un santo.
J’ai sauvé personne de mon vivant,
mais j’ai réussi en y passant !
Da vivo non ero granché d'aiuto agli altri,
ma da morto sarò un eroe.
Eu não ajudaria se estivesse vivo,
 mas serei um salvador como morto.
