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...
If we destroyed the Gyuki, you would die.
.إن دمرنا غيوكي فسوف تموت
Wenn wir Gyūki getötet hätten,
wärst du auch gestorben.
Si eliminábamos a Gyuki, tú morirías.
Si eliminábamos a Gyuki, tú morirías.
Si on détruisait le Gyûki,
tu disparaissais avec lui.
Se avessimo ammazzato Gyūki, tu saresti morto.
Se destruíssemos o Gyuki, você morreria.
Если бы убили Гьюки, умер бы и ты.
