I was a bit relived that the amazing "power" Gabimaru and some others humans had was not like "he was secretly a guru this whole time". It was interesting the direction they took, imo.

I wonder if Aza will start turning into a tree person like Houko. Those vines make me think he will be heading that route. Though they are far longer lived than normal people, so that does not seem to a now problem. Specially not the kind of thing Aza would worry about.

So you can learn Tao by hand-holding, the screwing part is completely unnecessary.

It didn't look like those "I have reason!" monsters were so worried about Mei for the sake of other monsters, they were totally planning to use her for themselves.

You can also learn Tao by eating humans that turned into plant (Ten) but I suppose that would be a crime in their society.
