“Yeee” is officially Natsumi’s catchphrase!
More name trivia! Since ThunderKid is about weather and most everyone in it is named for it, these kids are named after seasons since they affect weather too. They’re Japanese of course. The “haru” in Haruka means spring. The “natsu” in Natsumi means summer. The “a” in Aki means autumn. And finally, the “fuyu” in Fuyuki means winter.
