Hanabi

Expanding on The Seven Deadly Daughters 

Aspect: Sloth
The laziest, most apathetic of the sisters. She hates having responsibilities of any kind and would prefer to snooze the day away. 
Her demeanor is deceptive, however; all that sleeping and laying around is the only way she can tap into her full power. When fully awake, she's the fastest of her sisters and the heaviest hitter. Fortunately for her opponents, she also wears out the fastest, and that's IF you can convince her to get up in the first place.

She was named Hanabi after the beautiful and fleeting explosiveness of fireworks.
