It needs more info when it comes to how she can use his abilities. Did she learn how to use them? If so can she use them well? If not then she should have basic level awareness. Also it could use an event about how you're mother came to be attacked by a hollow. Also she needs an object to channel the power through if she's a fullbringer otherwise you should check out Orihime Inonue's page because it seems your closer to her than a fullbringer. Yes the medical set counts as it but it would need specific whats are whats in the set. Because it would mean different things do different stuff as opposed to the normal singular object does this like my cross. I think you know where I'm going with this. 

Also the grammar could use some work it has a couple of he's in there and I almost made it look like I was referring to her as a boy before double checking.

And the other weapons/armor/stuff thing didn't get deleted.

Unless I'm not seeing something otherwise I don't have any other problems with it.
