Naruto: From the Start, Might Duy Expelled Me from His School

Unfair! Shang Yuan Sen has been wronged worse than Dou E! He has just graduated and hasn't done a single bad thing, yet his master, Might Duy, kicks him out of the dojo. Even his junior, Might Guy, can't talk Duy out of it. Shang Yuan Sen asks in dismay, “Master, why?” Might Duy answers with a complicated look. “There's a bloodthirsty tyrannosaurus inside you. I'm afraid you'll cause trouble and drag Guy and me into it.” Shang Yuan Sen feels even more aggrieved. He thinks, I reckon what's inside me is a pufferfish. Sure, it's poisonous all over, but it looks adorably goofy and lovable. He doesn't argue with his master. Duy doesn't seem like the sort of person who'd worry about being dragged into trouble by him, so there must be more to it. Later, on his first ninja mission, his team leader is the son of the great scourge Shimura Danzō. Shang Yuan Sen kills him, ridding the people of one small scourge. On his second ninja mission, his team leader is a spy who has been undercover in Konoha for twenty years. Shang Yuan Sen kills him. Protecting Konoha starts with me. On his third ninja mission, his team leader is Sarutobi Shinnosuke, eldest son of the Third Hokage, Konoha's greatest menace. Shang Yuan Sen kills him and is overjoyed. Konoha is one step closer to an age of peace. Then the Hokage in the shadows and the Hokage turn against him, and he experiences the greatest malice the world has to offer. Only then does Shang Yuan Sen truly understand Might Duy. He claps his hands in praise: “Master really did see this coming. You cut our ties long ago so I'd have nothing to worry about and could slaughter my way across the world.”
