Now that you mention it, the person who got in trouble for that was uncensoring real porn, not hentai (or hentai games lol). I would imagine that uncensoring artwork isn't nearly as big of a deal legally as say a JAV video.
But either way, the censorship in the next Arika video is gonna suck
I don't think it's for uncensoring porn but for trafficking with it,because there are uncensored AV and hentai. There was a case of a guy who sold AV to minors to pretending to be AV = Animal Videos
The thing about uncensoring porn is something that you cannot do without permission in Japan, so they probably added the aggravating factor, but Japanese laws do not apply to people who do not live in Japan. If hypothetically there were a complaint, it would enter the law of your country and if that law does not exist, it cannot judge you
They could use the intellectual property law but if you don't make money it has no way and if it did you would just have to delete it and apologize publicly unless your work in some way does not benefit takeda, either losing sales or losing subscriptions or that you do such a horrible job that he considers it an insult to his work and in his honor there would be no problem because you do not harm him
