Don't pay attention to the title. It looks like a Naruto fanfic, but it's actually a ridiculous crossover where Madara goes wild in A Certain Magical Index.
A few things to note:
1. There's all kinds of nonsense and random crossovers. Keep some tissues handy to wipe away the blood, because this might make you spray it everywhere at any moment.
2. I'm definitely not going to tell you that Madara went from being a brother-con to a sister-con.
3. The writing is at an elementary-school level. If you don't like it, just hit X.
4. The author can't see the comments. I'll just ignore anyone who flames me as an idiot, so go vent in the account that might pop up at any moment.
5. I definitely recommend my master's book, Transmigrating from Fairy Tail.
