YukiBon

YukiBon is the slash ship between Yukio Okumura and Ryuji Suguro from the Blue Exorcist fandom.

Canon
Ryuji, who commonly goes by "Bon", is one of Yukio's brightest students in Cram School, where Yukio serves as his Anti-Demon Pharmaceuticals instructor. Being one of Bon's teachers might explain how Yukio knows a bit about him, when Yukio explains that Ryuji is the heir to a venerable temple in Kyoto to his older twin brother, Rin, after Rin and Bon got into a fight when Yukio handed out the results of their exam; that Bon scrod the highest in. Throughout the res of their classes and during the Training Camp in the woods, Yukio remained professional to Bon and the rest of his students. Bon didn't like how Yukio placed the whole class in deletion, when only he and Izumo Kamiki were only ones causing trouble in class before Yukio walked into the room, Yukio wanted Bon and the others to understand that no exorcist fights alone. That statement from Yukio later came in handy as Bon works with his classmates to keep a Naberius them in the dark, shortly after Yukio left them alone in a warded guarded room. After Bon manages to kill the demon, Yukio walks back into the room to find Bon and the others battered up just before the demon attack was revealed to be the exwire exam that Yukio had prepared them for. After Yukio's brother revealed himself to be the demonic son of Satan, Yukio explains to Bon and the others his brother's brief story to how he came to be at Cram School, along with the fact that while Yukio is Rin's twin brother he didn't inherit any of Satan's powers, which makes a normal human.

When one of the Impure King's eyes was stole and Yukio went to retrieve with a team, while Bon and the a few other exorcists went to Kyoto where the demon's other eye is kept, which kept both Yukio and Bon apart. Until the morning after Yukio's team arrives at the inn that is own by Bon's family, as Yukio makes his way to the spot where Bon and Rin faced the Impure King, after all traces of the demon were burned away by Rin's flames. Before Yukio and his class return to True Cross, he joins Bon and the other on their day off as they take in the sights of Kyoto as a group of friends. As they took a group picture at Kyoto Tower, Bon serves as the "S" while Yukio serves as the "N" as they, Izumo, Konekomaru Miwa and Renzo Shima spell out "SATAN" for it as a joke. As they were making their way back, the exorcists take a quick stop at the beach in order to take care of a Kraken, Bon has some fun with his friends on the beach before the demon showed itself, while Yukio kept his distance from his students as he was still troubled with what happened in Kyoto when he faced Saburota Todo, the man that got into Yukio's head, before and after Todo attacks Bon's father in order to take his familiar.

Despite still being troubled by the things Todo said to him and the reveal that he might had inherited Satan's power after all, Yukio continues to reach Bon's class as he over sees Bon and the others take on demons within the academy, as part of their training, all while keeping his discovery a secret. After they faced a ghost demon that only Bon's fellow male classmates could approach, the second demon required girls to make it appear before them, which is why Yukio had got Bon and the rest of the male students to dress themselves up as girls, so they could help Izumo and Shiemi Moriyama. By the time they were done "getting ready", the demon was already exorcized by Izumo and Shiemi. As Bon was getting annoyed that he embarrassed himself for nothing, Yukio began to wonder how a strong evil demon ended in the girls' dorm in the first place; since it wasn't one of the original demons that he should have Bon and the rest of the exwires face at their current level.

Fanon
While YukiBon isn't as popular as BonRin is in the Blue Exorcist fandom, it hasn't stopped fans from shipping Yukio and Bon together after a few YukiBon-like moments were shown in the manga's Blue Night Investigation arc. Just as the aftermath of the Illuminati arc stared YukiBon's rival ship, Yukishima. The slash is also commonly shipped beside ShimaRin. Even though the ship has a very small fanbase on AO3, while Fanfiction.net has 108 fanfics on the two with only two placed under pairing, YukBon still has a few loyal supporters.
