Cocky miss Natsu by Spearfrost. Natsu is Nicolai's younger sister, and she's a generally unpleasant person who goes through life speaking exactly what's on her mind, then stomping on some hopes and dreams for good measure. When your older brother is a crime boss, you're pretty much shielded from the consequences of your bitchery.

Natsu is my character.
