I mostly focused on the night aspect because I am a night person, I finished this at midnight for crying outloud! Anyway, the whole 'looks can be deceiving' fits in here. Her innocent looks gets her companions rather fast, but one wrong step and it's over. Strong and stubborn, but has an odd habit of leaning on others she's bonded with.
Edit*
I added a tattoo, the sign is Japanese for 'Night' which is optional (cos idk, some people are against them). If it doesn't win I'll probably try to sell the design someplace else or keep for a while.
