Masashi Kishimoto
In September 1999, the serialized version of "Naruto" premiered in "Weekly Shōnen Jump 1999 No. 43" and quickly became a hit. "Naruto" ended on November 10, 2014 after more than 15 years of serialization, with a total of 700 chapters collected in 72 volumes. Sales have exceeded 113 million copies in Japan and over 95 million copies in the US, followed by over 93 million copies worldwide (outside Japan and United States) as of volume 36. Making total sales for the series approximately 301 million copies. Kishimoto was also the winner of "Rookie of the Year" for the series in the Agency for Cultural Affairs. It was adapted into two successful anime series, "Naruto" and "Naruto Shippuden". Kishimoto requested that Tetsuya Nishio oversee the character designs of "Naruto" when the manga was adapted into an anime series. The "Naruto" manga series became one of Viz Media's top properties, accounting for nearly 10% of all manga sales in the US in 2006. The seventh volume of Viz's release became the first manga to ever win a Quill Award when it claimed the award for "Best Graphic Novel" in 2006. Responding to "Naruto"'s success, Kishimoto said in "Naruto Collector Winter 2007/2008" that he was "very glad that the American audience has accepted and understood ninja. It shows that the American audience has good taste... because it means they can accept something previously unfamiliar to them." While writing the manga, Kishimoto met Eiichiro Oda, author of "One Piece" who he considered his rival. When "Naruto" ended, Oda left a message in the series' final volume acknowledging him as a rival. According to Kishimoto "That felt so gratifying." Additionally, before the anime adaptation's premiere of "My Hero Academia", he praised Kōhei Horikoshi's work, believing it would be a success overseas. Additionally, Kishimoto referred to Yoshihiro Togashi as one of his favorite artists.
Naruto Uzumaki
When first introducing Sasuke, Kishimoto wrote him as a rival who never noticed Naruto. However, as the series continued, Naruto became strong enough to finally be recognized by Sasuke as a rival. He also intended both as brothers due to the fact both characters suffered loneliness, something which made the readers relate to them as he noted through fan letters. By Part I's ending, the bond between Naruto and Sasuke was weakened as a result of their fight but still expected the time when the Sasuke accepted Naruto as an equal. Kishimoto compared Sasuke and Naruto to the concept of yin and yang because of their notable differences. When one of the two progressed, Kishimoto made sure the other did too. Before the serialization began, Kishimoto had decided the ending would feature a fight between these two characters. He wanted the conflict to end with Naruto forgiving Sasuke as he had forgiven Nagato. By 2013 when the series was reaching its climax, Kishimoto told the readers to look forward to the final fight between the two characters. In regards to the fight, Kishimoto wanted to focus on hand-to-hand combat rather than ninja techniques. Anime staff Chengxi Huang said the animated adaptation of this fight, the group worked carefully to depict the action in every scene by showing changes on Sasuke and Naruto's clothes and hair. Huang added he felt fatigue by working so much into this fight due to reaching 70 successive cuts at a time.
