About Hanabi: Wants, and acts, like a boy, in order to gain her father's favor over Hinata, the current heiress, as she can see how Hiashi disapproves of Hinata's supposed weak will. Blunt and secure in the knowledge of her noble position, she uses her rank to her advantage.
Also likes stuff that blows up. Hey, whaddya expect with a name meaning "fireworks?" XP
