So I bought the Manga Science 3 book [as well as 6,9,13] for kindle online. It turns out it was ONLY available in Japan, so I had to adjust somethings, but it worked out. Since the books were about 4 dollars each, and I got them instantly, I don't consider it a waste. In fact, the books are pretty interesting. I'll say this; there is so much endo-bait here. Several topics about the human body are addressed, but only a couple or so have endo. The endo is better enjoyed with the context, since the visuals are not that great [really needs color]...but not terrible either. It's a cute series that may not always have endo, but there are some endo visuals [like body maps], as well as some moments that are inside the body [but only the cells, germs, etc]. Sometime after work [in like 19 hours or so], I will share number 3, and maybe some other findings from 6/9/13 along with some context commentary. If you have any suspicions of other volumes in this series that may have endo, it's just one click away for me.
EDIT [9/9/22]; Here's a google drive link to access some of the manga panels. I labeled the digestion one, and I will try to organize the others and maybe add more later. Some panels are not endo, but are some of the good endo bait lol. This manga series knows how to make a compelling story out of the endo, as well as have funny entrances and exits at least. Until the next find, enjoy.
