Mio's greeting ("selmat paggi") is a reference to Yukko from Nichijou. How is this tagged? There doesn't appear to be a "show reference" or "franchise reference" tag. Should there not be one?
I don't think so. It's simply a greeting in Indonesian language. (And if by any chance this was supposed to be a Nichijou reference, the tag you're probably looking for is parody).
