Kuro's classmate Aona is troubled by the popcorn that keeps popping out of his head. Aona says it makes him sad when the popcorn disappears, so Ramune lends him a bag that can be used to store the popcorn. Why is Aona's head producing popcorn, and why does he feel sad when it disappears? Ramune tells Aona that the treatment method will become clear if he asks himself those questions...
No way! I'm not letting you 
play out here at night!
!مستحيل! لن أدعك تلعب هنا ليلًا
Nichts da! Ihr sollt nachts
nicht draußen rumlungern!
Pas question que je vous laisse dehors
à une heure pareille !
Non se ne parla! 
Non ti lascerò giocare qui fuori di notte!
Não pode! Não posso permitir
que fiquem por aí de noite!
Ну уж нет! Я не позволю вам
сидеть тут ночью!
