Mika and Naruto Uzumaki

What if Naruto had a twin sister? What if said sister also had a demon sealed inside of her? Join the Uzumaki twins in their whirlwind adventures from passing the Academy to when Naruto goes to train with Jiraiya for two and a half years! Warnings of cursing language and adult themes. I do not own Naruto. I own Mika Uzumaki as an OC.
