ShinArthur

Arthinra 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. Although it hasn't been touched in the story, Shinra and Arthur already met prior to being assigned to Company 8 in the Academy, but is unknown how long they've known each other. 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 sometimes to add 'king' at the end and has to tack it on last second, which annoys Shinra to no end.

Obi takes the two out to Ippudo Ramen and the two start an eating contest.

Arthur accompanies Shinra to "save a dog" that was supposedly stuck in a tree, said dog ended being Mamoru. After getting the mascot down, they help out with handing out balloons.

They work together to fight off Setsuo, but Arthur is ultimately left behind after Setsuo flees and Shinra follows him.

Arthur gives Shinra more food during dinner.

In the opening they can be seen holding hands while falling towards an Infernal.

Fanon
