I did not see that coming

haha yeah but there is always room for improvement

I think that just may be where the "goth" concept came from. I mean, maybe "goth" was never a thing in Japan, so that particular type was borrowed from American schools (or TV shows and movies about American schools--and TV often makes it seem like our high school cliques are set in stone).

You know you're right. Closest they have is Gothic Lolita, but it's more fashion rather than preoccupation with the macabre (though I think there is Guro Lolita or something similar).

Yes--I think club gothic lolitas in Japan are very cute (like everything else)--it seemed weird to me that this high school makes "goths" take out earrings. I know they have uniforms, but that girl wasn't even wearing dark eyeliner or anything. How about a black ribbon or upside down cross for effect? :) It seems like she just wears a longer skirt.

Perhaps she was FORCED to get all those piercings as a Goth, but not necessarily expected to wear earrings in the holes since I think it would have been against school code?

Maybe. I think maybe they do not have a Hot Topic in Japan.

all this school concept is based on American stereotypes of teenagers in high school. From (prom) king and queen, to lower levels of popularity as goths and nerds. so i think that is the thing mangaka had in mind

And that girl in last chapter was forced to act like a goth and that's why she was crying for new sensei for leaving because now she need to act as a gloomy lonely character again

See, as an American, I don't see goths as lonely. They are dark, but they are not as weepy as emos--and even emos usually have other emos. (Nothing against goths or emos). Goths are closer to punk, or perhaps glam rock, but with different tunes.

Here is what the BBC says about it:
