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?
I only drink about half a glass.
...أنا أشرب نصف كأسٍ فقط
Ich schaff nur ’ne halbe …
Yo la mitad de un vaso.
Yo la mitad de un vaso.
Et moi, un demi-verre.
Io circa mezzo bicchiere.
Eu só consigo tomar meio.
