That isn't scary, since Yuuka's personality tends towards... being quite eccentric. Her smiling could mean she wants to battle, but it could also be... a smile.
This picture IS bad, though, in terms of "How Fucked Are You?".
Well I believe it would be remissible to assume that Yuuka was upset rather that simply smiling. I would certainly choose my words carefully when talking to her.
