Ninja's Pirate Journey

Second time travel? Ron, who died in the Ninja War, woke up again. He had arrived in the world of pirates, and the system was turned on by the way. Ron was ecstatic and saw the system mission: stop Shukaku. I said, Naruto world is not awakened, now I am a pirate, please awaken me, you are kidding me, right? This is the world of pirates! Where can I find a Shukaku for you? It wasn't until Crocodile was defeated and the system prompted that the task was completed that Ron had an epiphany. It turns out that people in the two worlds correspond to each other? But I don't know who corresponds to whom, what should I do? Then we can only fight them one by one.
