NARUTO: THE INHUMAN BEAST

Kumamoto Kuro transmigrated into the world of Naruto… only to discover he had become a black bear. Worse still, the era he arrived in was one of the bloodiest periods in shinobi history—the Third Shinobi World War. The Five Great Nations were locked in relentless battle, and even the forests between hidden villages had become dangerous battlegrounds. For a wild beast like him, survival was brutally simple: eat or die. After days of starvation, Kuro finally encountered prey—a lone ninja wearing the fan-shaped crest of the Uchiha Clan on his back. The man was clearly injured, his chakra unstable after a recent battle. But even wounded, an Uchiha shinobi was still terrifyingly dangerous. The clan’s legendary Sharingan was feared across the entire shinobi world for its ability to perceive chakra flow, copy techniques, and predict movements. But hunger left Kuro no choice. With desperation clawing at his mind and stomach, the massive black bear lunged. At that moment— [Ding—] [The Dazzling Japanese Celebrity Devouring System has been activated] [Possible consequences of devouring the current target:] I. Evolution into human form — 97% probability II. Awakening the Sharingan — 2% probability III. Other random effects — 1% probability [Choose to devour?] Kuro didn’t hesitate for even half a second. "Yes!" The next moment, the starving bear tore into the fallen Uchiha ninja. Warm chakra flooded into his body as the system activated, strange energy coursing through every muscle and bone. Kuro could feel his body undergoing a violent transformation, his vision burning as something unfamiliar awakened within his eyes. When the devouring process ended— Kuro had indeed changed. But not in the way he hoped. He had not evolved into a human. Instead, he had become— A black bear with the Sharingan. Two crimson eyes spun slowly in his massive bear skull, the black tomoe rotating around the pupil. "Damn it!" … Many years later, the Fifth Hokage, Kuro, faced a visitor who had descended upon Earth from the moon. It was Toneri Ōtsutsuki, a surviving member of the ancient Ōtsutsuki Clan. Toneri stared at Kuro in disbelief. "You! How do you have the **Rinnegan?! I was clearly the last strong member of the Otsutsuki clan!" Standing nearby, Kakashi Hatake glanced sideways at the bear-shaped Hokage. "So? What's your chance of winning against him?" Kuro: "30/70." "Three minutes, seven-tenths full."
