Well, Naruto could be used to represent gluttony in a positive way, as mentioned before with his love for ramen. For envy, Tenten might be a good choice. She often seems envious of the more powerful and unique weapons of other ninja. And for sloth, Ebisu could be a character to represent it, with his laid - back attitude and sometimes lackadaisical approach to his duties as a ninja instructor. As for the other sins, there are many other characters like Gaara who could be molded to represent pride in his new - found self - worth after befriending Naruto and the others.
