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...?!
When we took this picture
was the first time you smiled.
كانت هذه أول مرة تبتسمين
.فيها حين التقطنا هذه الصورة
Als wir dieses Foto gemacht haben,
hast du zum ersten Mal gelacht.
Al tomar esta fotografía sonreíste 
por primera vez desde que murió papá.
Al hacer esta foto sonreíste
por primera vez desde que murió papá.
Quand on a pris cette photo,
c’était la première fois que tu as souri.
Quando abbiamo scattato questa fotografia, 
hai riso per la prima volta...
Quando eu tirei essa foto, foi a
primeira vez que você sorriu.
На этой фотке ты
 в первый раз улыбнулась.
