Shouzou and Ine, an old married couple, are known to everyone as a pair of lovebirds. One day, they wake up to find they look like their younger selves! When Mino, their granddaughter, sees them, she's shocked by their transformation, and she's not alone!
This is bad. We've got our strong gramps 
and us on this side, and still...
هذا سيّئ. لدينا الأجداد الأقوياء

Hay que joderse,
C’est bizarre… On est forts,
Ferrou. Mesmo tendo a gente
e o nosso vô forte deste lado...
Почему так тяжело?
Против меня же старики!
