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.

They are the current most popular ship in the Fire Force fandom and growing as the story progresses.

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.
