Came across these on Amazon Japan, in the toy area. Strange thing to give a little kid, weird words to teach a little Japanese kid too.
Well, they’re certainly not meant for kids, are they?
Those characters are from “Panty & Stocking with Garterbelt”, a Gainax anime series styled after American cartoons like Powerpuff Girls and the likes, but with quite a lot of hentai content, too.
I think that makes it just either more hilarious or sad.
