The testing continues even at 32,000 feet. Mumei and his classmates are especially challenged when their plane begins to experience mysterious turbulence. Meanwhile, while on an outing with his classmate, Haku, Mumei encounters a new rival. Who is this young man and why does he know so much about pens?
I will not sell a pen to someone 
who isn't fond of pens.
لن أبيع قلماً لشخصٍ لا يكنّ للأقلام شيئاً

No le venderé una
a quien no las aprecie.
Je ne vends rien à ceux
qui ne tiennent pas à leur stylo.
Non vendo penne a chi non prova amore per esse.
Não vendo minha caneta para 
alguém que não tenha afeto por ela.
