Kurosaki wa, anata ga ikite iru kami ni kansha shimasu...

It's an outfit for one of her special missions, when team's pln was to create lots of fog to fight with sronger enemy... And I dunno, maybe Kurosaki got into troubles and she was scared of losing him... And when it came out he's allright, she was relieved, jumped in his arms and stuff. xD Yeah, they're such a cute couple. qwq'''
