Naruto Boren Legend was a sequel and had no direct connection with the original Naruto. Therefore, whether it was the first or not would not directly affect the quality or reputation of the work.
Naruto was a classic Japanese manga that told the story of a group of ninjas in the ninja world fighting to protect their homeland. It had already received widespread praise and recognition from readers and audiences. The Legend of Bo Ren was a sequel to the series that told the story of the growth and adventures of the protagonist Bo Ren.
If Bo Ren Zhuan was the first one, then it might be criticized because people might expect the sequels to better continue the theme and style of the first one. However, if it really is the first, then it may also be praised because readers may expect to see the series continue to develop.
In short, whether Naruto Boren Legend was the first or not would not directly affect the quality or reputation of the work. Instead, it depended on its own quality and whether it met the expectations of readers and audiences.
The first Naruto manga came out in 1999. It laid the foundation for the entire Naruto franchise, setting the stage for the adventures and growth of Naruto and his friends. The initial manga chapters were crucial in building the fan base that the series enjoys today.
