Kamijou Faction

The Kamijou Faction (上条勢力) or Kamijou Party is a "new group" which technically does not exist in any tangible form. However, the possibility of the "faction" becoming a proper entity is "feared" by certain individuals in the magic side such as Etzali (initially) of the Return of the Winged One, since it might destroy the actual balance of power between the magic and science ; the group "violates the regular rules" existent in current organizations since "it's composed" of espers, magicians and regular people who were allied with Touma, contrary to most organizations that use only magicians, only espers or only people unrelated to either side in their operations.

Initially the group is mentioned by Etzali and after that, its name is never mentioned by any other characters except Lessar as the story progresses, so the name can be considered as non-canon, but the individuals' connection with Touma are canon.

Background
Excluding Index, Touma meets his allies unexpectedly, and they help each other in many situations. Their connection with Touma were formed due to many reasons such as they have feelings for him (Misaka Mikoto and Itsuwa), they have respected him (Stiyl Magnus and Kanzaki Kaori respected him for saving Index), their lives were saved by him (Himegami Aisa and Lessar), they were encouraged by him despite they were not human (Misaka 10032 and Kazakiri Hyouka), and changed their ways of living after being defeated by him (Accelerator and Hamazura Shiage).

Etzali pointed out that the most troublesome thing about the group was that they took radical actions in order to solve problems and thus "couldn't be ignored", Etzali also pointed out that every member allies himself to the group out of their own volition, beliefs and conviction, and thus they would never betray Touma, can't be bribed out of the group and would not switch sides regardless of the consequences. He references on how the faction will survive even if Touma dies, as the bonds between the various members can't be dissolved.

Allies
The individuals below are not 'members' but rather people who were connected with Touma. Most of these people used to lead difficult lives or have problems that they could not handle, such as in Index's case, being a container of the 103,000 grimoires. Moreover, some of these people have been previously antagonistic towards Touma, such as Kanzaki Kaori. However, Touma helped them even if they refused his help, because of him, their lives were changed and they had become trustworthy allies which helped Touma in battle or other situations (except in his unlucky peaceful daily life and his homework). They are also grateful to Touma and believed in his strength. One of the evidences is confirmed, like his friend Tsuchimikado Motoharu who once warns Aleister that if he wants to use Touma for his unknown but selfish plans, Touma will break down Aleister's illusions.

Their relationships with each other in the story are normal (sometimes in a comedic way) when it is peaceful. But when a crisis occurs, they seriously helped each other so they can return to those peaceful days. Individuals like Etzali, Sherry Cromwell, and Vento of the Front were never seen helping Touma, but they used to fight him and they were defeated by him. After that, they changed their ways of living and had their own reasons for providing support.

Trivia

 * There are evidences that in the Magic Side mages and organizations believe that this faction is very dangerous and influential; while others want to join.
 * Etzali was one of the first to point out the danger that the so called group represents, regardless of that he ended up "allying" himself with the ideas faction.
 * After Lessar mentioned the 'Kamijou Faction', she said that she does not want to be a part of it. However, she did not abandon Touma and kept on assisting him during his journey to save Index. Her journey with Touma is solid evidence that she is one of Touma's allies.
 * Since Touma ends up related to several influential people, one could say that the faction has several resources. For example: Third Princess Villian, Elizalina , President Roberto Katze , Oyafune Monaka , or Kaizumi Tsugutoshi.
