Matataki convinces Umika and the others to start a school-sanctioned club to finance their rocketry endeavors. The next day, everyone in Umika's grade sets off on an overnight study camp.
I can't help but worry just 
as I'm about to go to sleep!
!لا يسعني إلاّ القلق وأنا أوشك على النّوم
Immer wenn ich im Bett liege,
drehen sich meine Gedanken im Kreis!
¿Por qué le doy vueltas a esto
antes de ir a dormir?
¿Por qué le doy vueltas a esto
antes de ir a dormir?
Toutes mes inquiétudes
ressurgissent la nuit !
Prima di addormentarmi
inizio sempre a preoccuparmi per qualcosa!
Estou prestes a dormir, mas
não consigo não me preocupar!
Я же спать собиралась,
а теперь так волнуюсь!
