I Became Zoro in the Naruto World with the Power of Light

Adam died on Earth and woke up in the Naruto world. He doesn't have a "System," but he has two powerful gifts: the Light-Light Fruit (giving him the speed of light) and a Mask that gives him the sword skills of Roronoa Zoro. In the Konoha Academy, Adam pretends to be just a weak, average student. Nobody notices him. But when he puts on the mask, he changes completely. He becomes a terrifying villain who follows no rules. He strikes with light speed and fights like a demon. He is so dangerous that even the Akatsuki are afraid to attack him. Madara warns his team:"Stay away from this 'Zoro.' He is too strong and will ruin our plans." Pain is shocked when he faces him:"I am the God of Pain... but you act like the God of Death."
