Try reading Naruto, a manga that lots of people know. Its about a ninja, named Naruto, who has a demon sealed inside of him, making the whole village hate him but after hard training and work, everyone learns to respect him. His dream is to become the leader. Later in the series, he becomes friends with Sasuke, another ninja who wants to avenge his family by killing his brother since his brother killed his family. It’s funny at times but gets more serious when the story progresses. I find it really good. =)
