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?
Don't you dare speak my name 
with that trash bin of a mouth.
لا تنطق اسمي بفم القمامة لديك
Wag es nicht, mit deiner Mülltonnen-Fresse
meinen Namen auszusprechen, du Made!
Basura, no te atrevas
a hablarme con esa boca.
Escoria, no te atrevas
a hablarme con esa boca.
Misérable !
Imbecille, non azzardarti a pronunciare
 il mio nome con la tua lurida boccaccia.
Maldito. Não se atreva a falar 
meu nome com essa boca imunda!
