Exwires

Exwires is the friendship between Rin Okumura, Shiemi Moriyama, Ryuji Suguro, Renzo Shima, Konekomaru Miwa and Izumo Kamiki (as well as occasionally including Yukio Okumura, Nemu Takara and even Shura Kirigakure at times) from the Blue Exorcist fandom.

Canon
Back when the main Exwires started out as pages, at the beginning of Cram School before Shimei joins them later on, they each kept to themselves and remined on their own small groups. As Izumo had dragged her only friend Noriko Paku into Cram School with her, just as Ryuji "Bon" Suguro had gotten Renzo Shima and Konekomaru Miwa to attend it with him as well, so the Kyoto Trio could restore their temple, while Rin never had any friends his own age growing up. The same with Shiemi, due to her shy nature, but is very fund of their young teacher and Rin's younger twin brother, Yukio, after both Rin and Yukio save Shiemi from a demon that was slowly possessing her through Shiemi's legs, she gets inspired by the twins to join Cram School where she stays by Rin's side, while getting the chance to watch Yukio teach up close.

Shiemi joining had set events that led to the other exwires properly getting to know one an other. By starting off with Rin and the trio from Kyoto when Bon had assumed that Rin was more fused on flirting with Shiemi than to study for their Cram School lessons, both Shima and Miwa try to tell their friend that butting heads with Rin isn't worth getting into trouble for, as Rin and Bon did end up getting themselves into during P.E., just as Bon "asking" Rin if Shiemi is his "girlfriend" had gotten Rin to say that he and her aren't friends which hurts Shiemi when she heard him say it. As their teacher has a quick word with Bon, Shima and Miwa tell Rin why their friend is serious due to what Satan, Rin's biological father, did to their temple during the Blue Night, Rin begins to see that he and Bon share the same goal. Izumo think that a lot like their is impossible and laughs at the idea of it, and as Rin and Bon fight over which one of them will be the one to defeat Satan, Shima and Miwa state that the two are very alike one another.

As Rin grew closer to the Kyoto Trio and were deciding on what their Misters should be, along with Shiemi wanting to be more independent than she was before, she tries to reach out to Izumo and her friend Paku to see if they'll expect her as their friend. Because Shiemi never had any friends and didn't know how they act with one another, Izumo takes advantage over it when she faulty excepts Shiemi's friend request. Moments before Shiemi became friends with Izumo, both friends show signs of having the ability to summon and tame demon while the rest of their classmates got nothing from the summoning circles that their teacher each one of them. When it was time for them to have their Training Camp, as they study to become exwires, the school led it at the abandoned Boys dorm that Rin and his brother are staying at. Rin didn't like how Izumo was treating Shiemi tries to talk about it with her, as that was happening and just as Izumo was preparing to have a bath, Paku tells Izumo that she wants to drop out of Cram School which upsets her and when they got attacked by a demon, Izumo's weary heart had gotten her two familiars to turn on her. Rin comes to her aid as he protects Izumo from the demons, while Shiemi treats Paku's injures before Yukio and the rest of their class enter the girl's bath room to see what had happened. Because Izumo was still in her undies when the rest of the boys came in and didn't want anyone of them to see her crying, Rin gives Izumo his shirt so she could cover herself up.

Because of what happened had troubled Izumo, she wasn't herself and began to pick a fight with Bon during class, which gets the whole class place in detention, together. Since no exorcist fights alone and Yukio wants them to understand that. When the same demon from yesterday attacks the class in the dark, they worked together to keep it at bay until they manged to kill it. The attack was then revealed to be their exwire test, before their teachers began to treat them.
