A test doesn't just assess your ability to answer complicated math or science problems, sometimes it's about how you present yourself. Koui finds out the hard way that not all tests are in the classroom. Her classmate, Anri, decides her friend needs some much needed "girl time" with Miss Ou but will it really be that simple?
Everyone, break out of your 
cocoon and become a butterfly!
يا رفاق، كونوا فراشاتً تغادر شرانقها
Schlüpft aus eurem Kokon
und werdet zu Schmetterlingen!
¡Sean una mariposa saliendo del capullo!
¡Sed una mariposa saliendo del capullo!
Vous aussi, devenez des papillons !
Ragazzi, uscite dal vostro bozzolo
 e diventate bellissime farfalle!
Pessoal, sejam a borboleta
 saindo de seu casulo!
