Wraith, and is later seen recovering in the hospital. Shinji Kazama is Sousuke's Arm Slave-loving classmate. He shares the same amount of passion for AS as Sousuke and could be considered Sousuke's best school friend besides Kaname. His father is Shintaro Kazama and a secretary of Narashino's Assault Machine Troop. Shinji's love for AS began when his dad failed to become an AS pilot. As a result of his father's failure, Shinji strives to discover the result of the failure and to fulfil his father's dream of becoming a pilot. There is no indication as to what happened to his mother, but it's assumed that Shintaro is a widower before the series started. Mizuki Inaba is a classmate of Chidori who initially blames her for having stolen her boyfriend. She becomes one of her closer friends later on in the series. Mizuki is easily infatuated with various men, who usually take an interest in Kaname instead. Eri Kagurazaka is an English teacher at Jindai High and is the class advisor to Sousuke, Kaname, Kyoko, Shinji, and Mizuki in Class II-4.

His behaviour is always calm, and he is never seen as angry. He often considers Sousuke's behaviour a reasonable response to the kind of situations he finds himself in, much to his frustration of Kaname. He assigns Sousuke to be the head of security in the Student Council, and Sousuke and Atsunobu share a mutual respect. On many occasions involving the school, Sousuke tends to treat Atsunobu just as he would a senior officer in the military, even to the point of calling him "Excellency" in the English dub. Atsunobu is also known for holding a white fan, on which various Japanese characters are written. In addition, he is seen reading famous
