Rakutan

This is a kekkei genkai that is unique to In'ei and her bloodline. Thanks to being part demon (from her father's side) she has access to this kekkei genkai. What it does is increase her speed, her strength, as well as cause her to undergo a transformation in which she grows black wings, her canines and nail sharpen, and her eyes turn a darker red. Lastly, the kekkei genkai strengthens her genjutsu abilities, as well as giving her access to more powerful and more brutal genjutsus.
