Yukko has always wanted to do something super awesome wonderful amazing, so the fact that she was brought here to save the world?  Yeah, big rise to her ego.  Yeah there were technicalities but Yukko would simply gloss over those details.  So once she arrived, she would have likely just jump in and start being a Shōjo heroine, right?

Nope.  Yukko was getting way too cold to really think about any of that.  Wearing your summer uniform out in the cold can be distracting like that! So she kept ducking in and out buildings just to avoid the cold.  But now all the stores are closed, so Yukko will be left to wander the streets aimlessly, with her arms wrapped tightly around her shoulders.

She might even come up to you, sniffling loudly and shaking violently.  Her expression can be described as cartoonishly pitiful.

"E-E- E-Excuse me."  Yukko whines.  She bows her head whilst trembling.  "D-D-Do you know where I am?"
