Is おはようです just weird


I'm watching the anime ひぐらしのなく頃に. There's a character in it who greets people
with おはよう **です**. At first I thought it was just a cute affectation, but then
I wondered, if おはようございます is okay then why not おはようです?

There seem to be quite a few hits on Google for this phrase. Is it a different
level of politeness? Is it a regional thing or is it just weird?

Grammatically, おはよう is a contraction of おはようございます, which is a Western dialect
form otherwise should be おはやくございます in Standard Japanese. Since おはよう as such is
not a valid word except for this fixed idiom, you can attach nothing to おはよう
grammatically.

Contrary to what was said in the previous paragraph, strictly speaking, です is
not prohibited to be attached to any phrases to make polite direct quotation
out of them, and you can certainly treat it as a simplified polite ending by
taking over this grammar. This usage is neither conventional nor standard in
Standard Japanese, so you can think it of a mildly broken grammar. A girl
speaks in off-point grammar is, some kind of, sign of cuteness.

Additionally, some dialects indeed use this versatile です as their normal way
of speaking. See:
