slur is what the yukkuri do by, well, "deforming" the words through similar sounds, but not the appropiate ones.
Like when a little kid instead of saying "mama" they say "myama" or instead of "daddy" they say "dwawwy"
This koalice is doing that, and it may had smitten you, specially because she isn't using the slur in a way that may trigger murderous intent like it happens quite often.
Maybe, but I don't think so (pics like Steamed Baby Yukkuri kinda bothered me, but not much). And yes, you're jerk. I so hoped that he gonna tease her a little bit and then release...
