All around Mana, humans are being stricken with a strange illness that turns them all wrinkly and causes them to fall unconscious. She notices that her classmate Tsutomu is acting oddly, but he keeps telling her to leave him alone. Worried, Mana goes to his apartment building. But, faced with his mother's piercing gaze, Mana runs away. That night, Mana tells Kitaro about Tsutomu and his mother's odd behavior. Wondering if it's somehow connected to the strange illness, Kitaro and Cat-girl go to Tsutomu's apartment. What they see there, the truth behind the illness is...?!
He's a tricky yokai who'll just regenerate
if you only attack his body!
إنّه يوكاي مزعج سيستمر بالتعافي
!إن هاجمت جسده فقط
Ein äußerst hartnäckiger Yōkai, der sich sofort heilt,
wenn nur sein Körper angegriffen wird.
Por mucho que ataquemos el cuerpo de 
Onmoraki, es un yokai capaz de recuperarse.
è uno yōkai complicato da affrontare, 
perché risorge subito, se si attacca solo il suo corpo!
Ele é um Yokai traiçoeiro que regenera
se você apenas atacar o seu corpo!
