That ankle funnel guy is seriously the absolute worst. Holy shit, I'm at a loss of words at how overdesigned that crap is.
This stuff is obviously also beyond garbage. Worse though, this one in particular reminds me of that anime Suisei no Gargantia which I felt pretty meh about overall anyways but I couldn't believe how blatant the fucking fan service in there was.
The main female character (and her friends for that matter) even did some ridiculous belly dancing in one episode and damn, the whole art style is so... urgh. This kind of red glow on their shoulders and checks which is like some kind of perma-rouge. Even if I felt like the anime executed well on the kind of story it tried to tell (which had some very serious and somewhat interesting ideas) I couldn't take it seriously when you constantly get huge tits or half-naked characters shoved in your face and they even do 1-2 fanservice episodes right in the middle. Just what the fuck.
Seriously, search for the belly dancing scene and tell me that's not just creepy considering they're like 15 or sth, belly dancing for an audience consisting to a large degree of grown up men.
Naruko Hanaharu, the main character designer of Suisei no Gargantia is a famous (maybe notorious for you) hentai manga artist, what else do you want from him? This is how Japanese anime industry working in reality, they really have a decent job for a hentai manga artist, and his name could attract more otaku audience.
Things like "Mature audience will never accept Japanese artists sexualize little girls/underage/youngsters/female characters" is a very weak social justice agenda. If our communist government taught me anything about social justice, it's about social justice is the worst thing on this planet, it's basically nothing but admit how weak your culture/law/national strength is. If you want to achieve social justice, you make a law to forbid, you take the dispute land by force, you arrest hentai manga artists across national boundaries and put them in your jail, in this way you can tell the world "this is fucking bad and should go to hell", this is how social justice being served, not using agendas to encourage censorship or witch hunt.
If America can make laws to anti such sexualiztion in ACG world, that will be respected, and there will be no Japanese game dev/anime artist dare to show these to their honorable foreign audience again. Kojima will change Quite's design, Kamitani could never make that fanservice, and Suisei no Gargantia won't give Naruko Hanaharu any job. If this is what you want, that's how to achieve it, acting like "I am such a sane mature human being, I know how bad this is, you guys who enjoy and support this are silly perverts" won't help at all.
