Nerugui in Naruto

Nerugui, a loyal companion of Kahiko and his clan, has a strong bond with the royal bloodline. This connection makes him reserved around those not part of the clan. He first appeared when Naruto, Sakura, and Shikamaru embarked on a mission to locate him. The task proved challenging due to Naruto's lack of understanding.

Complications arose when they encountered Haido's knights, including Temujin, resulting in a skirmish. Following an intense altercation between Naruto and Temujin, during which they tumbled off a cliff, Nerugui was eventually returned to Kahiko and the clan.

Interestingly, Nerugui's loyalty took an unexpected turn as instead of remaining with Kahiko, he spent more time with Temujin. Subsequently, he played a pivotal role in an altercation against Haido. Unfortunately, Nerugui was defeated in this encounter, leading to the reversal of his aging process.

This was achieved by regurgitating the Stone of Gelel, an artifact that had restrained his aging. Eventually, Nerugui departed alongside Temujin for a new and uncharted territory.

Nerugui is cautious and devoted, valuing his clan's royalties. He's initially wary of outsiders, like Naruto's group. He's brave but not immune to defeat, as seen when he confronts Haido. Despite his loyalty to Kahiko's clan, he accompanies Temujin after their encounter.

Nerugui has four whiskers on each side of his face and black fur around and behind his ears. A unique tan diamond-shaped spot marks the center of his forehead. Nerugui is a tan-furred ferret with red eyes and black accents on his nose, feet, and lower legs.

Nerugui can use its claws quite well, which he did against Naruto, and he is quick.
