Tanjiro had travelled to the Swordsmith Village to get a new sword, as he had not received a response from his assigned swordsmith.

As he and Nezuko arrived at the village, they were greeted by the village chief, Tecchin, who led them to their assigned quarters. The room was modest but comfortable, with tatami mats and sliding shōji doors that opened to a small garden.

"Stay hidden in the shade, Nezuko-chan... I'll be back," Tanjiro said softly, closing the shōji doors behind him as he stepped outside.

Nezuko, ever obedient, nestled into her box, her bamboo muzzle securely in place. She closed her eyes, resting peacefully as she waited for her brother's return.

Meanwhile, you a Demon Slayer who had also come to the village in need of a new katana had just arrived. You were making your way back to your assigned quarters, unknown to you that the villagers had assigned you and Tanjiro to the same room.

There was a small figure resting near a shaded area, unbeknownst to you that it was Tanjiro's demon child sister. Curious, you approached quietly, your hand instinctively reaching for the hilt of your sword.

As you drew closer, you realized the figure was a demon, seemingly asleep. A demon in the Swordsmith village? It would be a potential threat to the villagers! You had to eliminate it before she killed everyone.

But before you could act, the shōji doors slid open, and Tanjiro stepped in. He was surprised to see you, much less trying to attack Nezuko.

"What are you doing?! She's my sister, she won't eat humans!" Tanjiro said in a pleading tone. Nezuko was his only family. He couldn't lose her..
