Receive the arrow.

After a few days, you find yourself eating breakfast when Yin walks in with a message. The rest of the girls are out doing various things.

"Somebody is at the door for you, Master," she says. "I believe it's the weaponsmith. Shall I allow her inside?

"Please," you reply. You finish down the last bite of your sandwich as the devil vanishes in a plume of smoke.

A few moments later, she walks back into the room, but with the ginger girl behind her. She's still wearing her same outfit, and probably came rushing over the moment she was finished. Laira has a small metal case with a handle in her hand, and a look of absolute excitement on her face. She hurries over, pushes your plate out of the way, and slams down the case in the center of the table. With two clicks, she undoes the latches, and prepares to pull it open in front of you.

"Are you ready?" she asks with the lid in-hand. "I worked day and night, and I think I'm about to pass out, but it was totally worth it. I've never made such a fantastic weapon in my life."

She slowly lifts the lid, and as she does, you're almost blinded by a sudden radiant glow. It sits perfectly in a holder personally designed. It really is the most beautiful arrow you've ever seen. The shaft, head, and every other part is pure gold. A thin purple line spirals up from the bottom all the way to the tip. The entire arrow is luminescence with a divine white light, and inscribed in tiny letters along the shaft is the name. You reach down to pluck it from its holder, and you hold it up to inspect it closely--warm to the touch.

"But how...?" you mutter.

"Impressed?" She smiles proudly. "It was a complicated procedure of processing each of the ingredients, mixing it all together... If I went into the details, we'd be here forever, but the reagents can effectively be organized into a sequence to construct the magic item in such an ingenious way that there's no way anyone would stumble upon it by accident. This is the work of exceptionally intelligent craftsmen, probably over a long time. I can't believe it either."

You place it carefully back inside and shut the case. "Our trump card."

"Are you really going to go fight a Demon King? I didn't even know there was one nearby."

"Nearer than you'd care to know."

"Well, good luck with it. I hope my arrow does you good. If you make it out in one piece, I'll give you a discount on equipment repairs. A Demon King's base must be full of treasures as well, right?"

"That would be a great reward on top of it all. And thanks. I'll do my best."

"Guess I'll get back to work for now."

"Please allow me to escort you back outside," Yin says with a curtsy.

Laira laughs. "I can't believe you've even got a cute devil maid here. Thanks. We'll let your lord here think about what's ahead."

"He's my master," Yin replies as she begin to depart.

"Master? Is that like... an intimate thing?"

"Wh-What do you mean?"

You shake your head as the voices fade. With a long exhale, you lean over the metal case, and stare at the wall across the room.
