Subaru has begun living with a cat as a roommate. He realizes he's run out of cat food and goes to a pet shop to buy more, but starts to panic when he's surrounded by creatures he's never been around before. Then Nana, a shop employee, starts to talk to him, asking him questions about the cat's name and age. Subaru then realizes he hadn't thought of a name for the cat yet. Nana tells him that he should give the cat a name because it's his family now, so Subaru tries to think of one, but nothing good comes to mind. As he's pondering, he comes across a book in his room called "The Moon and the Sun"...
After all, I can eat food 
whenever I'm hungry now!
Jetzt kann ich ja fressen,
wann immer ich Hunger hab.
¡Ahora puedo comer
siempre que tenga hambre!
Ahora puedo comer
siempre que tenga hambre.
Surtout que maintenant,
je peux manger quand j’en ai envie.
Quel che importa è che adesso 
posso mangiare ogni volta che voglio!
Agora posso comer
sempre que sentir fome!
Теперь я всегда могу поесть, 
когда захочу кушать!
