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...
He may have indeed become an Odoro-Odoro,
but we only have his word on the attacks.
،قد يكون أصبح أودورو-أودورو بالفعل
.ولكن كل ما لدينا هو ما يقوله بنفسه عن الهجمات
Er stimmt wohl, dass er zu Odoro-Odoro wird.
Se convirtió en Odoro-Odoro, pero no 
sabemos si realmente lastimó a alguien.
Se convirtió en Odoro-Odoro, pero no
sabemos si realmente hirió a alguien.
Même s’il est devenu Odoro-odoro,
Che sia diventato Odoro Odoro è certo,
Ele pode se tornar um Odoro-Odoro,
mas só temos a palavra dele sobre os ataques.
Конечно, он вполне может превращаться в 
Одоро-одоро, но нельзя верить ему на слово.
