Adding to that, the idea of her first skill was pretty fun to think of, and the sole reason why I keep the comical name on it.

Since Nagisa is a Berserker who can't stop thinking about cheese (even though she actually hates eating it), I thought it would be a splendid idea if she had the ability to suddenly "see" something as cheese. That's where the "random trait apply debuff" came from--as in she suddenly saw an enemy in the field being cheese. The sure hit comes from being unstoppable from trying to eat the "cheese". And all that is a perfect setup for her NP which deals with chomping!
