Future #Iwaoi + #SakuAtsu ft. Miya twins and OiAtsu friendship Part II - to have each other’s backs Rated G (for now), A #Haikyuu Harry Potter AU. __ Atsumu has had roughly two weeks to acclimatise to the idea of being a wizard.

Granted, when a friendly giant showed up to rescue him and Samu from their divorced, no-good uncle, he’d been skeptical. Having to ask for platform 9¾ only to have the conductor laugh in his face didn’t improve matters either.

It was just his luck that just as Atsumu was beginning to grow agitated, they were spotted by a dark-haired boy. “Are you looking for platform 9¾?” The boy had said, eyes briefly flickering to Atsumu’s forehead. When Atsumu confirmed that yes, in fact,

that was exactly what they were looking for, they were led to a brick wall. Suffice to say, it was one of the most bizarre experiences in his life, and he’d been sleeping in a too-small cupboard with Samu for eleven years. He didn’t catch the boy's name,

but it’s the least of his concerns now. It’s Atsumu’s time to take his turn with the sorting hat. Iwaizumi’s words bounce in his head. It’s said that the hat 𝘸𝘪𝘭𝘭 consider his choice. Atsumu is ready to bully it into compliance if it takes,

to never set foot in Hogwarts again if the hat dares to separate them. Osamu is the only constant—the only 𝘨𝘰𝘰𝘥 thing—in Atsumu’s life. He's all Atsumu has. Since he can remembers it has been the two of them against their neglectful uncle, fending for themselves.

They would’ve starved if Atsumu hadn’t resorted to shoplifting, if Samu hadn’t taught himself to cook using a dusty old recipe book his Uncle’s ex-wife left behind. So Atsumu takes a seat and thinks, without preamble, as soon as he's greeted by a gruff voice,

“Listen—I’ll cut to the chase. I don’t care where ya throw me. I hardly care where ya see my potential. I only care ‘bout one thing. My brother stays with me. He stays right next to me. You’ll make it happen. I don’t care if ya have to invent a fifth house.

Samu goes where I go or the entire wizarding world can go ta hell for all I care.” And the hat? The hat 𝘭𝘢𝘶𝘨𝘩𝘴. “You think you can bully me, young wizard?” “I’m prepared to try.” The hat laughs again, sounding terribly amused. Atsumu’s stomach twists into painful knots.

He can’t 𝘭𝘰𝘴𝘦 Samu. The hat needs to understand that. “I sense plenty of courage in you,” the hat concedes. “A determined young one you are. Fiercely loyal and quite resourceful. I think I know just where to place you, little one.” “Remember what I told ya,”

Atsumu thinks furiously, ignoring the unfamiliar words. He struggles to remember being praised even once in his life. “Samu stays with me.” “I will take it into consideration,” the hat acquiesces, and just as soon declares for the entirety of Hogwarts to hear: “Slytherin!”

The table on the farthest left roars to life with applause and cheers, whistles rising above the commotion. Atsumu has never been cheered on for anything—not even once in his life. His feet find the floor with a shaky breath as he approaches his house.

Boys and girls of all ages are hooting his name, clapping wildly every step of the way until Atsumu comes to a stop before them. They part for him like the sea, making a space in the middle of the table. The tall, blond-haired girl next to him offers her hand for a handshake.

“Tanaka Saeko. Head-girl.” “Pleasure,” Atsumu manages, eyes already turning to the platform. Osamu takes a seat, eyes catching his own warily. Atsumu tries to reassure him with his eyes alone. 𝘞𝘩𝘢𝘵𝘦𝘷𝘦𝘳 𝘩𝘢𝘱𝘱𝘦𝘯𝘴, 𝘐 𝘨𝘰𝘵 𝘺𝘰𝘶.

As soon as the hat touches Osamu’s head, however, it slyly announces: “Another Slytherin!” A relieved sigh shudders out of Atsumu. He hadn’t even realised how nervous he’d been until now, when something tight and painful loosens in his chest.

Their table thunders into another round of applause, so loud and prolonged it makes his ears ring as Osamu calmly approaches his side. His hand grips Atsumu’s shoulder, a wordless 𝘵𝘩𝘢𝘯𝘬 𝘨𝘰𝘥. Atsumu scoots aside to make space for him by his side,

and reaches to squeeze his shoulder in return. A wordless 𝘸𝘦 𝘴𝘵𝘪𝘤𝘬 𝘵𝘰𝘨𝘦𝘵𝘩𝘦𝘳 passing between them. Turning his eyes back to the stage, he sees Oikawa, nerves twisting his expression into something painful to look at. Since he’d met the boy earlier that day,

he'd been oozing confidence and playfulness. The hat is unceremoniously placed on his head. They wait… and wait… and wait. Finally, a little shrilly, the hat declares: “Slytherin!” Atsumu’s eyebrows shoot up. Oikawa’s face goes pale.

Atsumu follows his wide-gaze to the Gryffindor table and suddenly, he understands. Sympathy churns his gut. They seem like good friends, Oikawa and Iwaizumi. Bantering and insulting each other good-naturedly. Wordlessly, Atsumu stands, catching Oikawa’s gaze. And wordlessly,

Oikawa stumbles to his side, features ashen despite the ecstatic claps and cheers. Atsumu pulls the boy down between him and Samu, a protective hand on his shoulder. Another wordless thought passes between him and Samu when honey-brown eyes lock with steel-grey eyes.

𝘞𝘦’𝘭𝘭 𝘱𝘳𝘰𝘵𝘦𝘤𝘵 𝘵𝘩𝘪𝘴 𝘰𝘯𝘦, 𝘵𝘰𝘰. “Hey,” Atsumu says lowly, despite the curious eyes that never stray from him. He waits for Oikawa’s anxious gaze to find him. “Hey,” he says again when he hears Oikawa’s shuddering exhale. “It’s gonna be okay. We’ve got ya.”

Osamu nods. “We’ve got ya.” Oikawa swallows before summoning a shaky smile. “Thanks,” he whispers with a nod. He turns his head one final time to look in Iwaizumi’s direction and finds him already looking. Atsumu nods, hoping he’ll understand the nonverbal sentiment.

They have Oikawa’s back. Iwaizumi nods back. “Sakusa Kiyoomi,” Atsumu hears, just in time to catch sight of a familiar dark-head of curls. “Slytherin!” The hat cries, and Atsumu finds himself smiling.

Their eyes catch for a brief moment as Sakusa makes his way past him, nodding slightly. Yes, indeed, the strangest friendships are bound to bloom under the green emblem of Slytherin house.
