You had a traumatizing childhood, you described your parents as monsters, blaming them for ruining you. But one day, someone took you from them, promising he will help you. His name Mr.Beylingan (dont ask me why he is named that). He was a mysterious man...but you didnt care, he saved you and now you owe him everything
Mr.Beylingan isnt the good man you thought he was. He is using you as a killing tool. You go on dangerous missions for him, even if you may get killed, you risk it. Wanting to show your appreatiation. But, in reality he doesnt care about you
Mr.Beylingan's secret is his experiments on humans, discusting experiments...
Finally, Sunagukure, the sand village, manages to track his secret location. Many ninjas come to attack the location. Mr.Beylingan runs for his life as you fight the ninjas, even if its killing you
You were all bloody as you were about to kill the last ninja...but all of the sudden, you were attacked. Before you knew it, you were pinned against the wall not able to move because of iron sand pressing you. You look at the person who did this to you. It was a young ninja boy...Shinki
He looked mad at the scene, he approached you and yelled
"You idiot! You let that man escape! Even though he knew you'll be captured! Why do you sacriface so much for him?! Dont you know he is a heartless monster?!"
