ShinArthur

ShinArthur is the slash ship between Shinra Kusakabe and Arthur Boyle from the Fire Force fandom.

Canon
Arthur and Shinra are both third-generation pyrokinetics working as Fire Soldiers of Company 8. Shinra and Arthur already met prior to being assigned to Company 8 in the Academy, knowing each other for around four years. Shinra apparently knows Arthur well enough to accurately interpret his sounds, like "hmph" which to others would sound like he's acting cocky or stubborn; but to Shinra it's just Arthur being "too stupid to come up with anything to say."

A common argument they would have is whether knights or heroes were better, with Arthur on the side of the knights and Shinra on the side of the heroes. After Shinra told him that "knights were wussier than heroes" Arthur started declaring himself the "knight king" instead of just knight. He seems to forget to add 'king' at the end sometimes and has to tack it on last second; which annoys Shinra to no end.

Although the two have their disagreements and often bicker, Arthur does have some amount of concern and cares for Shinra. After Shinra starts acting weird and feels better after cooking dinner and talking with Takehisa; Arthur gives Shinra more food from his plate since Shinra's appetite improved along with his mood.

Season 1 (Chapters 1-90)
Arthur accompanies Shinra to "save a dog" that was supposedly stuck in a tree, said dog ended up being Mamoru. After getting the mascot down, they help out with handing out balloons. After the alarm is called of the appearance of an Infernal, Arthur hops on Shinra's back so that they could get to the Infernal quicker. They work together to fight off Setsuo, but Arthur is ultimately left behind after Setsuo flees and Shinra follows him.

They fight together and are shown to have exceptional teamwork and sync, and they often cover each other’s back. In Asakusa, Arthur deflects an arrow shot by Arrow towards Shinra. And when Shinra is distracted by the horned Infernal and is about to be struck, Arthur pushes him aside and takes the blow with his sword. After when Shinra starts to spiral, Arthur yells at him to snap him back to his senses. Shinra and Arthur trust each other enough in battle to make sure that any plan they make carries out, which is demonstrated when Giovanni attempts to kill Vulcan to take the key of Amaterasu.

At Vulcan’s workshop, when Sho threatens Shinra, Arthur immediately runs over to him, risking his life to check on Shinra, When Arthur is struck in the chest, Shinra calls out for him. Afterwards, when Licht drives the pickup truck to get them, Shinra carries Arthur and stays by his side. Before Licht speaks, we catch a glimpse of Shinra’s extremely worried face. Afterwards, when they eat together, Arthur steals some of Shinra’s food to ask him where he was during the attack. To conclude the episode, Shinra and Arthur accompany Vulcan to his workshop so he can pay tribute to his grandfather and father.

Arthur and Shinra go to Asakusa to train with Benimaru, constantly being spooked the second they walk into the 7th’s headquarters. They are on edge until Benimaru instructs them to feel the breath of life. During their sparring against Benimaru, Shinra and Arthur are in perfect sync. Shinra is instructed to work on his finishing move while Arthur spars with Benimaru. After Shinra places great effort in working on his move, Benimaru decides to watch him. Arthur tries to attack him, but Benimaru counters him easily. Shinra looks at the fallen Arthur with concern. Once the sun starts to set, Benimaru suggests to wrap it up for the day. Shinra helps Arthur up and asks how he’s doing after sparring for so long, but lets go once Benimaru attempts to kick them. Afterwards, when they’re holding sparklers, they try to blow on other one’s sparkler without noticing their own has gone out.

Just before company 8 is set off for the Nether, Shinra is shown sleeping on the top bunk with Arthur sleep talking below him. In the matchbox, Arthur asks Shinra if he’s scared. Shinra replies with a no. Because of the fog, they become separated.

When Haumea tries to capture Shinra after he’s impaled, Hinawa shoots at Haumea’s head while Arthur rushes in. Arthur swipes at her head but gets deflected. Arthur looks at Shinra’s wound and declares that he’s the one who will kill Shinra (more specifically the “demon”) and tells him to not die. Shinra tells Arthur about what he knows of Haumea, then coughs up blood. Once he sees this, Arthur tells him to shut up and stop talking. The rest of company 8 get Shinra and leave the Nether, which is collapsing.

When Shinra is dispatched from the hospital, Vulcan informs him that Arthur is a “real pain” without him. After entering the company 8 headquarters, Shinra finds Arthur at his desk scribbling away at papers. Arthur looks up at Shinra, saying that it looked like he “hadn’t made it to heaven”. Shinra retorts by asking if he still hasn’t gone completely rotten and that he was an “oniony bastard”. Sparks of tension fly immediately but are broken once Hinawa opens his office door.

In the after-credit scene, Shinra is attempting to cut onions without crying while Arthur speedily chops up lettuce. Noticing how slow Shinra’s moving, Arthur smirks and aggravates him, causing them both to chop extremely fast. During Oni’s speech, Arthur steals Shinra’s food and refuses to give it back.

Season 2 (Chapters 91-174)
While Shinra is out shopping with Maki, Tamaki, and Iris, an Infernal warning is issued. Without his fire resistant gear, Shinra fights the Infernal but is struck down. He is almost hit by a fireball made by the Infernal, but luckily it was avoided because Arthur spilt the fireball in two. Arthur says that it’s a knight’s duty to protect the weak, which makes Shinra mad as he yells at him. The rest of the company arrive and Shinra goes inside the matchbox to change into his gear, later reappearing with Arthur to deflect the Infernal’s fireball.

At company 4, Shinra introduces Ogun to Asako. Ogun states that Shinra didn’t have any friends so he and Arthur stuck with him. Shinra denies it, saying he and Arthur aren’t friends. Ogun responds with “yeah right”.

Later, when Shinra is possessed by the Sister-lookalike, Arthur and Ogun arrive to help restrain him. Arthur expresses how annoyed he is at what Shinra’s doing, then explains he’s supposed to be his bodyguard. When he sees Shinra’s face, he notices that he isn’t in the right state of mind. After Shinra and Arthur trade blows for a bit, Arthur asks Shinra where his conviction of being a hero went. Shinra says he “burned it all up” to which Arthur asks if it’s really him saying it or if it’s “whatever’s inside him”. Arthur gives him four chances to come back to his senses. Shinra immediately uses one. He forces Arthur to fight to kill, and Arthur remembers how Shinra said being a hero was a promise he made to his family. He decides to use it against him, and Shinra starts to spiral. After Arthur headbutts him, Shinra kneels on the floor with a bleeding nose, asking him where is he supposed to direct his bloodlust. Arthur tells him to protect the ones important to him. He asks him if he’s a hero or a demon, demanding an answer, fully ready to cut him down based on the answer. Shinra yells in frustration and kicks himself in the face, coming back to his senses. He tells Arthur that it was a dumb question and says he’s a hero.

While walking back to company 8, Shinra is lost in thought until Arthur brings up what happened. Shinra apologizes to him, and Arthur swipes at him, saying Shinra isn’t that agreeable. Shinra retorts with that he’s agreeable to people that aren’t as awful as Arthur, and Arthur retracts his blade. Shinra admits to Arthur that wondering about the truth won’t get them any closer and that he’ll keep his promise with his mom and Sho because he’s a hero.

During the Adolla investigation mission, when the boat lands in the Chinese Peninsula, Shinra, Arthur and Ogun rush off the boat. Shinra and Arthur start yelling that they’re in a new continent while Ogun says they need to find soil. They run off to find soil, and when they do they start eating the soil out of excitement.

At the pillar near the Tabernacle, Shinra insists on investigating the area ahead. When Pan questions him, Shinra’s tic appears and he states he won’t let anyone get in the way of knowing the truth of the Great Cataclysm. Arthur grabs his shoulder to look at his face and make sure he isn’t losing control again, but Shinra swats his arm away. After Scop and Pan argue on whether or not they should take back the Oasis, a Hell Hound bites down on Shinra’s behind. Arthur immediately kicks it away.

When the talking Infernal says the Tabernacle is a weapon to destroy the world, Arthur and Shinra discuss the validity of the Infernal’s words. Arthur suggests that the Infernal is right, and Scop attacks him in the side saying he’s wrong. Shinra agrees with Scop and declares he won’t let anyone use the Tabernacle for destruction.

A bit after Shinra takes back the oasis by killing the demon Infernal, the investigation team is seen by a fireside outside the oasis. There’s a shot of Arthur, Shinra and Ogun all sleeping together, Arthur’s head is on Shinra’s stomach and Ogun’s foot is on Shinra’s face.

In the company 8 headquarters, after Benimaru and Joker storm the Holy Sol Temple, the group along with Konro are having a meeting, discussing on how they should handle the situation. Arthur suggests bursting in like Benimaru did, but Shinra opposes, arguing it’s too dangerous. They start bickering again as usual.

While sweeping the leaves outside, Arthur points his broom at Shinra, accusing him of being a Haijima spy. Shinra sarcastically replies that he could be one, only if he was going to assassinate Arthur. Due to his nature Arthur takes him seriously and attacks him, then Shinra counters. They accidentally hit each other and start a full-blown fight. Vulcan uses his machines to step in.

Later when everyone is in Obi’s office to hear what Licht has to say, Licht explains that the facility Shinra was once in was researching Adolla Bursts but couldn’t find one in Shinra. Arthur calls him a lightweight and Shinra asks him why he’s the one laughing.

Arthur finds Shinra's nervous smile cute, even though he constantly makes fun of Shinra for it. Many fanworks depict them as good friends who bicker in public but a lot more friendly behind doors or alone.

Because the two canonically share a room, some fanworks revolve around the two sharing a bed.
