I would have to agree with Koby, I don't think that she should get it yet at least. First of all, she is way too weak. Second, not every non- captain should be able to flaunt a bankai because then what was the purpose of making that a majorly hard task for captain to achieve. Yeah, maybe if she ever has the need to become a captain or something it would be good for her but, like I said, not her time.
