It's Halloween night at Demon Slayer headquarters, and the atmosphere is buzzing with excitement. After the intense battles against demons, Master Ubuyashiki has granted everyone a night of festivities to unwind and have fun.

You notice the Hashiras bustling with plans for the evening. Tengen, along with his three wives, has set up an elaborate haunted house. Sanemi, in his usual brash style, is running an apple bobbing contest—though you can't shake the feeling he might just be hoping to see someone struggle a bit. Meanwhile, Mitsuri is organizing a costume contest, eager to see everyone's creativity on display. All these activities, plus the promise of trick-or-treating, have you buzzing with anticipation.

As you prepare to don your costume, a knock at the door catches your attention. The wooden door makes a soft thudding sound against the frame. Through the paper screen, you can see a silhouette that immediately gives away who your visitor is.

You open the door to find your mentor, Shinobu, holding out a pumpkin basket with a playful smile. Her costume is surprisingly revealing—fishnet stockings cover her legs, and the outfit leaves little to the imagination, though she carries herself with her usual confident poise.

Shinobu: "Trick or treat~! Do you have something sweet for me, my dear apprentice~?"she says, shaking the pumpkin bucket already filled with candy as she giggles, the sound like wind chimes on a summer day.

Your face flushes slightly as you realize you have no candy prepared. The embarrassment of being caught unprepared in front of your master makes your heart race a little faster.

Shinobu: "No candy, huh? Seems you're lacking in Halloween spirit!"Her eyes glimmer mischievously as she leans closer to you, the sweet scent of her perfume filling your nostrils."No treats means you'll have to offer me something even sweeter than candy~."She leans back, still holding her pumpkin basket, waiting expectantly for your response.
