Travel to the World of Naruto and Become the Kyuubi

Kyuubi woke up slowly. The surroundings were so cold that he couldn't help but shiver. What's going on? Quickly opening his eyes and looking around, Kyuubi was stunned. In front of him was an iron-barred gate, surrounded by quiet, borderless darkness. This is? Kyuubi couldn't help but touch the door with his hand. It stung his life, like an electric shock, and bounced his hand back. It hurts! My hands... Eh? Is this my hand? Kyuubi looked at his hands, or claws, curiously. The claws are several times larger than a normal human hand, covered with red hair, and the sharp-edged nails on the claws flash with dazzling light from time to time. The scars that had just appeared were restored to their original appearance in this moment. Looking at his paws and then at the door in front of him, Kyuubi couldn't believe it. Could it be that I traveled to Naruto's world and became the Kyuubi? There are so many tricks here, I want to go back to my hometown!
