Demon Slayer Swap Au

Chapter 4

In Asakusa Nezuko stood looking at the city with Tanjiro standing next to her. Nezuko stares at her surroundings in awe, "Are the cities this advanced now? It's nighttime, but it's so bright out! These buildings are so tall, What is this? The cities.... The cities...' she sighs, "I feel dizzy" She says.glancing around, before taking Tanjiro's hand, "Let's go that way Tanjiro '' She says and points towards an alley. As they walk into the alley only to find two people making out, "Ah! I-I beg your pardon!" Nezuko yells as she runs out of the alley pulling tanjiro along with her.

They run somewhere and find an udon shop, Nezuko glances at the shop walking up to the shop, "Excuse me?" Nezuko asks the man. The man glances up at the two of them, "A bowl of udon with grated yam on top please!" Nezuko asks the man.

"Sure thing!" The man says turning around to make the udon.

'I've never been to a place like this, it's way to crowded' Nezuko thinks

"Here's your udon with grated yam on top!" The man calls.

"Thank you very much!" Nezuko says as she's about to dig in. She glances at Tanjiro who was about to fall asleep, she smiles slightly before Tanjiro suddenly perks up with wide eyes. He glances at Nezuko before stealing Nezuko's sword and running. Nezuko drops the bowl of udon in surprise, "Tanjiro!" She yells and starts running after him. Tanjiro had started running into the street with Nezuko chasing him, 'What is he doing...? Why did he take my sword?' She had so many questions running through her head at that moment but that was when she felt it, a presence stronger than any she had ever felt before. When she caught up to Tanjiro she noticed he had a hand on an older man's shoulder with a glare directed straight at the man.

The man had turned around to glance at Tanjiro, Nezuko noticed a slight fear in his eyes as he glanced at Tanjiro.

Nezuko took a step back as she looked at the man who was staring at Tanjiro. The man had dark red eyes that looked extremely similar to Tanjiro's. Nezuko knew at that moment that this man was a demon. She stared in shock as Tanjiro's hand started pulling out Nezuko's katana

"Papa!" Nezuko heard a girl call and both her and Tanjiro froze, as the man turned revealing a small child in his arms. "Who's that?" the girl asked.

"It's alright don't worry" THe man reassured the girl.

'He's- is he- This is, Kagaya...? Isn't it-?' Nezuko stares, it's the only reason Tanjiro would have a reaction like this,' Nezuko thinks staring at the man, 'And he's living here- Pretending to be a human' Nezuko thinks bringing her hand up to her face.

"Is there something I can do for you?" Kagaya asked, "You both seem quite flustered" He said. The fear that had shown in his eyes had disappeared.

"Oh my what's going on?" A female voice asks

"Kaasan!" The small girl calls out

"There humans! THe girl and the woman... They're both humans!" Nezuko thinks. Tanjiro had a tight grip on Nezuko's sword, with it still slightly pulled out of the sheath.

"Do you know them?" The woman asks Kagaya.

"No, much to my consideration, I've never seen these children before" Kagaya says, "He must have mistaken me for someone else" Kagaya says before with his free arm he scratches the neck of a man that was walking by. Nezuko see's it happen and pushes through the crowd.

"STOP!" she yells as the man that was scratched started attacking his wife. The man bites the woman's neck; she quickly tackles the man and restrains him. Tanjiro and Kagaya stare at each other for a moment almost as if having a telepathic conversation.
