Naruto is a Japanese comic and Anime show created by Masashi Kishimoto. It’s about Naruto, a young ninja who wants to be the best in his village and lead it someday.
The Naruto font was made specifically for the show, but sk89q made a similar one called Ninja Naruto Font that anyone can use for free.
You can get a free download of the Naruto Font here. It’s in the TTF (TrueType) Format and you can use it for personal and commercial purposes without paying.
