Koyuki is a normal high school kid with a big problem: he can't stop himself from screaming at his crazy friends. He swears to himself each day that he'll stop, and each day he fails.

¡¿Y tú a qué asientes?!
¡¿Y tú a qué asientes?!

Perché mai stai annuendo?!
Com o que você está concordando?!
Чему ты там киваешь?!
