Sting like a Ninja. Im kind of thinking she might try to kill Aizen at some point for what he did to her. I know, it sounds silly and highly unlikely but, um, that's my thought. Meaning that it wouldn't be brute-force 'just burn everything' like Ryuujin Jakka, but some kind of more strategic fire ability with roots in kido. All of the colored chapters we have! I think it's called Flying Plum Tree because the shape of the sword is similar to a branch.
