Kamijou Faction

The Kamijou Faction (上条勢力 Kamijou Seiryoku) or the Kamijou Party, is an unofficial faction that techniqually doesn't exist, but exists in its own form and are the main protagonists of the entire Toaru Majutsu no Index series and its sequel series as well. Formed at an unknown time, the Kamijou Faction is made up of the many friends and allies of Touma Kamijou and they all work together when gathered in order to help him and assist him in his goals (mainly protecting people and Academy City). The organization itself is unknown to its members but is known all across the Science and Magic Sides so much that its said to pose a major threat between both worlds according to Etzali.

Background
The Kamijou Faction itslelf was fromed at some point in time when Touma managed to make new friends and allies with many people usually by unexpected situations and the encounters are all unintentional. Touma's very protective and heroic personality often leads to the people he meets to stay with him and become his allies for various reasons such as; Etzali also points out the various relationships that have been formed by the various members of the faction both with Touma and/or his other allies. This has become the most troublsome according to Etzali as the faction members have taken radical actions in order to solve problems that they and/or Touma were involved in and thus, they couldn't be ignored. Etzali also points out that the members of the Kamijou Faction are in the organization becuase of their own personal beliefs and motivations and can't be bribed out since they've all sworn never to betray Touma due to the bonds they've all formed with Touma and each other and vise-versa. Etzali also points out that even if Touma were to be killed, the faction would survive nontheless due to the bonds created between the various members.
