One day, in spite of the fact that her little sister Hinata has been sent off on an errand, Miyako spends her time wearing her same old track suit, engrossed in a game. Her mother, Chizuru, can't stand seeing her daughter like this and gives Miyako money to go out and buy new clothes, but...
You didn't go and make a secret 
little sister somewhere, did you?!
Non dirmi che ti sei fatta 
una sorellina segreta mentre ero via?!
Não me diga que fez uma irmãzinha em
segredo enquanto saia para algum lugar!
Ты что, завела себе тайную 
младшую сестру?
