Prologue

Disclaimer: I don't own Naruto series or any other series that may appear in this fanfiction. I only own jutsu and characters created by me.

In these almost hundred years shinobi villages are around, there were only few people that were feared through the world. First two that were feared were Hashirama Senju and Madara Uchiha, founders of first shinobi village Konohagakure. They were known as people that crossed line between humans and gods. There wasn't a single person that could defeat any of them except for themselves.

Then there was Tobirama Senju, younger brother of Hashirama. While slightly weaker than his brother, Tobirama had extraordinary ability to use water release, being able to bring water molecules from air.

Another people worth of mentioning were Hiruzen Sarutobi, student of Tobirama, Ōnoki of both scales, wielder of Dust release, and Ay from Kumogakure. They had one similar trait and that's that they were all third leaders of their own villages. They led their villages through hard times and were regarded as best leaders of their villages of all time.

The last one worth mentioning was Minato Namikaze, Konoha no Kiiroi Senkō. He ended Third Great Ninja War by killing thousand Iwagakure shinobi alone.

But even all those men doesn't compare to man that appeared sixteen years ago from out of nowhere. Nobody knew his name but everyone agreed on calling him 'Demon Butcher.' He was the only person on whom all shinobi villages worked together to find more about him. In years he is known to population he already killed more than 500,000 people, civilian or shinobi.

The leaders of each village agreed to cooperate to find him and made it international law that if anyone found any information on Demon Butcher they need to tell it to everyone. This man was danger for every village and they didn't even know if he wasn't from their own village. That was why all leaders gave order to each other to check all of their villagers, shinobi or not. But in the end after two years they didn't find anyone.

The Demon Butcher became myth, a legend if you want. He was man that parents used as boogieman for their children. He was even listed in Bingo Book under rank SS+ with order to run away if you see him and pray you aren't his prey. He was rumoured to be so strong that all kages, living or dead, wouldn't be able to kill him even if they were to work together.

But five years ago he suddenly disappeared. Nobody knew what happened with him. The kages agreed to keep him in bingo book if he ever returned so they would have at least some information on him. After five years they thought about taking him from bingo book, thinking that he is dead. Boy will they be surprised when he will return back and will turn whole world upside down.
