Some more info now that I've translated the second chapter... I'm using google translate and jisho . org to translate this (and some help from people who know Japanese better than I do for some more difficult parts) and while certain bits may not be 100% accurate I'm hoping to make Tezuka stuff more accessible. Most of this is so hard to find!
Some trivia on names:
Yanma refers to a big dragonfly, especially Green Darners.
Ageha means Swallowtail, and according to jisho especially Citrus Swallowtails, but her coloring matches an Eastern Tiger Swallowtail much more.
Mamezo means bean boy, which I believe is just a cute nickname. Searched around for some sort of bean-related beetle but I really couldn't find much.
