The principal adores his grandson very much and asks the Sket-dan to prepare a picture play to entertain him. They decide to base the story off of Momotaro, but change things up from the usual... Afterwards, he asks them to play with his grandson for an afternoon, but the kid doesn't seem interested in having fun at all.
Surrounded by Obaa-nyan's 
love, she grew up in a flash,
Gracias al amor de Obaa-nyan, 
ella creció en un parpadeo
Gracias al amor de Obaa-nyan, 
creció en un abrir y cerrar de ojos
Com o amor da Obaa-miau, 
ela cresceu num instante
