To aru hi no taiiku no jikan
During PE class on a certain day...

Kyō kara tairyoku-zukuri no tame ni, jugyō hajime no jūppunkan wa guraundo hashiru zo 〜
Starting today, to build up stamina, we'll run around the field for 10 minutes at the beginning of class!

Eee 〜!?
Whaaat!?

Gee 〜…… konna samui no ni jikyuusou toka yatterannē 〜
Ugh... It’s freezing and now we have to do endurance running? No way...
