Fuyumi-chan has forgotten to meet up with a friend.
Meanwhile, Noa-chan is being treated like a pet by the older students. 
When asked about the item on her back, Noa-chan replies, “this is a weapon! You'll get hurt if you touch it!” 
What is this weapon?
Because they say drinking milk 
makes your chest bigger.
لأنّهم يقولون أنّ حجم الصّدر يكبر 
.إذا شربنا الكثير من الحليب
Weil die Brust doch
durch Milch wachsen soll.
Parce qu’on dit que boire du lait,
ça fait grossir la poitrine.
Beh, dicono che se bevi latte,
 il seno ti diventa grande.
É que dizem que beber leite
 faz os seios crescerem.
