@yufang97:
Some of Teppei's stuff already had had a thing going where there's a children's-book quality to the art, themes and the structure of storytelling, and the protagonists are childlike (and usually rather precious), but the content sometimes isn't, in a way that can really catch one off-guard. (Special mention to, in Samurai Usagi, the protagonist's wife's backstory)
In past works, it was especially interesting to me because it doesn't come off as something done for the sake of being edgy; indeed the stories would seem to genuinely espouse a softer, more optimistic world-view, while still being set in a world where terrible things happen as they are wont to.
...This manga, on the other hand, goes a bit off the deep end, so who knows. So far I kind of still expect morals (or perhaps human empathy?) to win out in any scenario by this author—but I'm less sure what's going to happen with, say, issues pertaining to various dimensions of sexuality, which are not really fundamental moral issues so much as societally-acceptable-behaviour issues.
Of course I could have Teppei pegged completely wrong, too. I've had that thought more than once or twice while reading this so far... >_>;
