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...?!
And his soul resides
in Tsutomu-kun's mother.
.وترقد روحه داخل جسد تسوتومو-كن
Und seine Seele steckt in Tsutomus Mutter.
Y el alma está dentro 
de la mamá de Tsutomu.
Y el alma está dentro
de la madre de Tsutomu.
Et son âme se trouve
à l’intérieur de la mère de Tsutomu.
E la sua anima 
è dentro la madre di Tsutomu...
E sua alma reside dentro
da mãe do Tsutomu.
И сейчас его душа 
находится в матери Цутому.
