Then

 after a few moments the heart attacked us and that was the start of a new war that took place for more than 1 year.

 After the war was finish they came to a decision to not fight and sign a peace treaty .

In all these years of bloodshed war I lost humanity the only thing I knew was killing and fighting. Then I decided to quite killing and be a nice person after some time I started to stop killing.

 I went to the spades and told them to forgive me and make me a part of the village but they did not listen to me.

Then my anger grew big and big and the thing that I feared most about happened that was soul eater was starting to grow. Then in an hour my anger made me out of control .Soul eater started to rise and made my body as it’s vessel.

The seal that Minato sensei did was starting to broke and suddenly I became unconscious and I saw an dungeon where an beast was sleeping I asked who are you?
