Well, doesn't have to be a relative
She just falls into the 'little sister' archetype, is the plan

Unsure where I will start her off though at the moment.

Edit:
In regards to the weapons
I just say no to it
Haven't seen anything about that, and breaking down any weapon would probably make it shatter and be destroyed before it could be made into another

Edit again:
I was planning on her being a dagger or claws, but since you guys chose that, I am going to see if there is another weapon to choose, to try have more variety
