She's sacrificing her holyness for the greater good. If those two keep roaming around, lostbelt doesn't even begin to describe how screwed up that world will be.
I like how her headbang can expresse how HyperAggrasive Jeanne are after all the never ending chaos and torture.
So aggrasive that Anna would question : "Oh god what the hell actually happen to her"
Not as Aggrasive as Slippery Little Jack Chasing you down for thousand of miles and stab you whenever you stop
