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...
Please kill me when
I become the Odoro-Odoro.
أرجوك اقتلني حين أتحول
.إلى أودورو-أودورو
Bitte töte mich,
wenn ich zu Odoro-Odoro werde.
mátame cuando me transforme 
en Odoro-Odoro.
mátame cuando me transforme
en Odoro-Odoro.
Tuez-moi la prochaine fois
que je perds le contrôle.
Mi uccida quando diventerò Odoro Odoro, per favore.
Por favor, me mate quando
eu me tornar o Odoro-Odoro.
Убейте меня, пока я окончательно 
не превратился в Одоро-одоро.
