Prob around 13-17 in Japan age? or below .. idk they re supposed to be like middle schooler or something. They must've been hard to find someone who's experienced enough to pull that live action
The people in this live action are actually the same people who voice the characters in the show. Exempli gratia, Hanamori Yumiri is the one who voices and acts as Nadeshiko, and she has a really nice Japanese camping channel! (´∀`)
