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 totally forgot I was supposed 
to meet up with you, Noa-chan.
.نسيتُ تمامًا أنّ عليّ أن أقابلكِ يا ناو-تشان
Ich hab total vergessen, dass wir
uns treffen wollten, Noa-chan.
J’avais oublié
notre rendez-vous, Noa…
Mi sono completamente scordata
 del nostro appuntamento, Noa.
Desculpe, Noa-chan, esqueci 
totalmente que a gente ia se encontrar!
