Shintarō Natsume (夏目 慎太郎, Natsume Shintarō) A soft-spoken, third-year student and an underling of Hajime Kanzaki, he shows exceptional interest in Oga and his exploits. Handsome and long-haired, he prefers to make light-hearted quips during frays to engaging in them personally. Though he rarely participates in fights himself, he is incredibly strong, taking out the MK5 by himself and even downing Kaoru Jinno, and underling of Toujou Hidetora's within seconds. From this it is implied that Natsume is significantly stronger than previously credited, as not even Kanzaki or Tatsuya Himekawa were capable of such a feat. He shows these fighting skills again when he blocks Hiromichi Gō from attacking Oga head on, later stating during their fight, "It's not really my style to go all out in a fight."
