Takeshi Yamamoto, commonly referred to as Yamamoto, is one of the main characters in Katekyo Hitman Reborn!. He is generally warm and friendly, and is rarely seen without a smile on his face. He is rather naive to the point of believing that the Mafia is nothing more than a game and that his life isn't in any real danger. Takeshi is a fairly-tall teenager with short, spiky black hair and large brown eyes. He bears a strong resemblance to his father. In the future, he has a scar on his chin. His most prominent outfit is his Namimori Junior High uniform. He wears a black sweater, with a white formal shirt underneath, and gray pants. Unlike most of his other allies, Takeshi hardly ever wears a tie with his uniform. Takeshi is the type of character that can make friends with everyone, and if not friendship, then at least respect. Characters like Hibari, have been shown to have interest in Takeshi's battles, and Squalo has also shown to have interest in his development to the point of willingly tutoring him. However, Takeshi can become angry when his friends are hurt or injured. He is also willing to sacrifice things important to him to save his friends from danger.
