Tags like ex-keine and achi_cirno have these, so it must be something we do... We can skip the small fry, though.

Do we even need (append) tags for Megurine Luka and below right now? None of them have official designs, so the tags mostly contain speculation and cosplaying.

Meh. They're clearly mimicking the style...

The tags will be used in a ( more or less) near future, but I don't think it should have been created merely for fan speculation either, at least until we get Osamu's designs or anything else official. A character or cosplay tag is enough in my opinion

Done for Miku, Rin and Len for now.
