Nice combo, isn't it XD
I think 1 and 2 could have been switched it would still work
I'd rather not be rude, a greeting is always first XD
But yes, that works too
There is nothing rude about it.
The laugh is the first half of the greeting. The “hi” is the second half.
Well, not sure about that, there is a scene where he laughs and says bye but I don't know about the hi XD
I would call that the demon lord greeting~
