Toki then shows up with the chocolates that fans had sent to them. A few days later, a new face shows up at Itsuki’s house. Itsuki was getting ready to do his final return for his taxes and all of his possessions are carefully inspected by the new figure...
You fool! Age has nothing 
to do with little sisters!
Du Vollspacken!
¡Idiota! ¡La edad no importa
con las hermanitas!
¡Idiota! ¡La edad no importa
con las hermanitas!
Abruti, y a pas d’âge
pour être une petite sœur !
Idiota! L'età non ha nulla a che vedere
con il fatto di essere una sorellina!
Seu tolo! Idade não tem nada
 a ver com irmãs mais novas!
Дурак, возраст здесь ни при чём!
