Always and forever (read the description)
First of all, sorry for my grammar mistakes. Ok, so my first 3 chapters had been deleted, so I will write here what's the start of the story about. So Kai wanted as always more power, and now he can have it. He made a pact with someone, and now he is the most powerful ninja, but he lost all his memories. He starts to fight with the others ninja. If you want to see what happens next, read the story. Ps it's a very emotional story…
