Tying the Knot: Giyuu & Sanemi's Guide to a (Not so) Perfect Wedding

I. Step One: Announce the Wedding (And Brace for Impact)

The sun was just beginning to dip below the horizon, casting a warm orange glow over the Demon Slayer Corps headquarters. It was the end of another long day of training and missions, and most of the Hashira were gathering at the courtyard for dinner—a rare moment of calm amidst their hectic lives. There was a slight chill in the air as autumn settled in, but the atmosphere among the Hashira was comfortable, filled with soft chatter and the occasional burst of laughter.

Sanemi Shinazugawa, however, was far from calm.

He stood just outside the courtyard, his arms crossed over his chest, glaring at the entrance as if it had personally offended him. His jaw was clenched, his expression caught somewhere between a snarl and a grimace, the only thing betraying his unease the way his fingers drummed impatiently against his bicep. Giyuu Tomioka stood beside him, calm as ever, though even he couldn't help the subtle furrow of his brow.

"Are you going to tell them or not?" Sanemi snapped, his voice low but sharp.

Giyuu turned his head slightly to glance at Sanemi, his expression unreadable as always. "I thought we agreed you would tell them."

"That was before I remembered what a pain in the ass they all are," Sanemi growled. He shifted on his feet, clearly uncomfortable with the situation. "Why the hell did we decide to do this in the first place?"

"You were the one who said we should tell them all at once," Giyuu reminded him, his voice calm but with a hint of dry humor.

Sanemi let out a frustrated sound that was somewhere between a groan and a growl. "Yeah, well, I changed my mind. This was a stupid idea."

Giyuu said nothing for a moment, his gaze moving to the entrance where the rest of their friends were gathered, completely oblivious to the storm that was about to hit them. The corner of his mouth twitched—perhaps it was nervousness, or maybe it was amusement at Sanemi's obvious discomfort. It was always hard to tell with Giyuu.

"You wanted to make an announcement," Giyuu said quietly. "Now's your chance."

Sanemi scowled, running a hand through his white hair in frustration. "This is ridiculous. They don't need to know. What difference does it make?"

"They're our friends," Giyuu said simply.

Sanemi snorted, but the retort he'd been about to make died on his lips. He might not have admitted it out loud, but Giyuu had a point. As much as Sanemi hated to admit it, the other Hashira had become something of a makeshift family over the years. As annoying as they were—and they were annoying—they were still his comrades. His friends. And this was... a big deal.

Still, that didn't make it any easier.

"Fine," Sanemi muttered under his breath, clenching his fists. "But if any of them start acting like idiots, I'm leaving."

"Understood."

With that, the two of them started toward the courtyard. Sanemi's scowl deepened with each step, while Giyuu remained as stoic as ever. As they approached, the sound of conversation grew louder, and Sanemi felt his stomach twist with an unfamiliar sense of dread. This was not the kind of thing he was used to dealing with. Demons? Sure. Life-or-death battles? No problem. But announcing that he was getting married ? That was a different beast altogether.

As they entered the courtyard, all eyes turned toward them. The Hashira were seated around a long, low table, plates of food in front of them. Rengoku was in the middle of telling some boisterous story, his voice loud and full of enthusiasm, but he paused when he saw Sanemi and Giyuu approaching.

"Ah, Shinazugawa! Tomioka!" Rengoku greeted them with his usual booming voice, his face lighting up in a wide grin. "Join us! We were just talking about—"
