Slayers in a Demon's World {Demon Slayer x The Promised Neverland}

012: Planning

"First comes the rope. Let's go back into the house to find it," Y/n glanced at the overshadowing household and began jogging over to the entrance.

"Wait!" Emma lunged forward and grabbed Y/n's arm, yanking her backwards. "There's already a tracker on us. Don't you think it's dangerous? Maybe there'd be cameras or bugs!"

"There's no need to worry, Emma," Nezuko patted the girl's back from her position between her and Norman. "I'm pretty sure Y/n has it sorted out."

"Yeah. Last night, I checked the house out. There was nothing of those sorts around," Norman shifted on the cobblestone ground, grinning while Y/n entered through the door.

"We should find out how tight the security is before we escape," Nezuko pulled Emma in who was astonished at Norman's action.

"Who would've thought we were the ones bugged and not the house. I was careless," Norman hung his head before Y/n patted his shoulder, whispering to him to 'keep his head up'.

"Though... do you think Mama might've found out that we went to the wall?" Emma cautiously looked around, examining the hallways.

"I'm not sure about that..." Nezuko replied, trudging up the stairs ahead of Emma while she was holding the railing. "If that was true last night, she didn't realise that we were there. It would've meant that she doesn't know where we are at all times. She only knows where we are after checking her watch."

"If the transmitter's signal could identify us, then Mama would know if she checked last night on the way back or during lunch break," Norman stopped at the top of the stairwell behind Y/n and Nezuko.

"I've told Giyuu and Shinobu to take the ten suitcases back down," Y/n whispered before turning to the rest.

"But that's not the case," Norman held his hand out as Nezuko nodded and turned to them. "At least, I don't believe it is. I don't believe she knows specifically which three of us children were there, otherwise she wouldn't have made such a roundabout show of warning us. She would've just threatened us three directly."

"So..." Nezuko murmured, hanging her head in thought.

Suddenly, Don and Shinobu appeared down the hallway together, talking about some issues in both the rooms before they acknowledged the four's presence ahead. "Hey Norman! Can you help for a second?" Don called out.

"Y/n! We need you in the room! Some of the children are crying!" Shinobu also shouted as the two raced over.

"Something's wrong with the clock in our room," Don began chatting with Norman as Y/n and Shinobu hurried down the hallway, leaving Nezuko and Emma alone.

"Chris accidentally walked into the cupboard and all the books fell out! We also have to hide our Nichirin blades in the forest or else Mother might find them in our suitcases," Shinobu whispered as Y/n nodded and they rushed into the girls' room.

"We have to act like nothing happened," Nezuko muttered, staring at the eight pictures in a square on the wall. It was a gallery that Emma had explained. They were drawings of what the children at the house treasured.

Emma placed her hand in the middle which had obviously held a space for a picture. But it was taken down, probably by Isabella. "This was where Conny's drawing of her and Mama..."

She looks pale when talking about her... It must be a harsh reality for someone like her. Nezuko stared at Emma's hand with concern before acknowledging Norman's entrance when he opened the door.

It will be okay. We can do this. First, we must find some rope... Emma was stuck in her thoughts before she felt a looming presence above her. She turned around and met face to face with...
