Depends on what you're into. If I'm going off you liking Naruto, some I'd recommend would be: One Piece, Katekyo Hitman Reborn, Bleach, Full Metal Alchemist, Nanatsu no Tazai, Hunter x Hunter (2011), & Magi.
As in in general: Code Geass, Death Note, Baccano, Cowboy Bebop, Shingeki no Kyojin, Terra ForMars, Parasyte, Akame ga Kill, Steins;Gate, Berserk, Durarara, No Game no Life, Noragami.
Also, all I've listed have an anime adaptation so you can have fun watching them. Hope you enjoy any of these recommendations. Happy reading/watching.
