Shintarō Natsume

is one of the main protagonists of the manga Beelzebub.

Appearance
Natsume is shown to be a handsome young individual with long red hair. He commonly wears a hoodie when not in school uniform

Personality
Natsume is an extremely laid-back and mysterious character. He normaly displays mild amusment to most situtations, even dangerous ones other characters are serious about. He likes to keep tabs on people he finds "interesting" such as Kanzaki at first and then later Oga. He seems to have some sort of hidden agenda as while he is technically an underling of Kanzaki, he has displayed strength that far surpasses the other delinquents, having been able to single-handedly defeat the MK-5 and fight on equal terms with a member of the Rokkisei. In an extra episode of the anime, Himekawa stated that Natsume had no need to follow Kanzaki, and Natsume answered by saying that he only did it because it was fun since Kanzaki was so active.
