Danshi Koukousei no Nichijou character tags

I have no idea what's going on with some of these Danshi Koukousei no Nichijou tags, but I don't know enough about the show. I'm talking about the qualifiers and why some use the show name, while others seem to use their school name or nickname. Here are those of concern.

asano (ojou-sama no nichijou)
bungaku shoujo (yassan)
habara (joshikousei wa ijou)
ikushima (joshikousei wa ijou)
nagase (ojou-sama no nichijou)
president (sanada north high)
ringo-chan (president of sanada east high)
toyokawa (ojou-sama no nichijou)
vice president (sanada north high)
yanagin (joshikousei wa ijou)

It's definitely not easy, necessary, or standard, and there's no reason why they shouldn't just be changed to the show name or rearranged. For example, president (sanada north high) could be changed to sanada north high president.

They should all use _(danshi_koukousei) - think we can safely shorten it to that - if they're all from that show. Qualifiers don't need to be more specific than that. Aliasing. If someone has a good reason for using something else, we can change the alias.
