xD Well, first, this was the chapter. Not sure what RAWs you were looking at but we are working from the actual volumes we bought, and this is the full chapter 55.
Second, what Amane says for the smooth criminal line is "口説き魔" which basically means smooth talker, someone who keeps flirting around.
If you still dislike Smooth criminal, then I'm sorry, but I really don't want to go into a debate again whether the way we translate certain phrases or words is good or not, because we lost a lot of motivation last time with the whole oshi thing.
Edit: just saw you edit your comment, still, same thing. I'd prefer if there were less complains.
