In town, blood-sucking incidents are growing frequent. As Kitaro investigates, he receives a letter. The sender wants to be killed. Kitaro goes to visit the sender and meets Onozaki, a genetics researcher. Onozaki has created immortal cells and conducted an experiment where he injected himself with them. As a result, he has obtained an immortal body and also turned into a youkai. When he transformed into a youkai, he lost control and went seeking blood. All the recent blood-sucking incidents were Onozaki's doing. Because of the immortal cells, Onozaki can't kill himself, so he begs Kitaro to kill him, but...
I'll gather people like this
and have my father drink their blood.
.سأجمع أشخاصًا هكذا وأجعل والدي يشرب دماءهم
Ich werde solche Leute finden
und mein Vater ihr Blut trinken lassen.
Reúno a gente así y hago que 
papá les chupe la sangre.
Reúno a gente así y hago
que papá les chupe la sangre.
Je vais réunir ce genre de personnes
et laisser mon père sucer leur sang.
Radunerò questo genere di persone 
e farò succhiare a papà il loro sangue.
Eu vou reunir as pessoas assim e
fazer meu pai beber seu sangue.
Я соберу таких людей 
и дам отцу выпить их кровь.
