JJK x KNY: The Spider Lily's Curse

Lullaby in Dreams

Blood splattered on the seats and floor of the train and Nezuko looked shocked as a huge slash just appeared on the boy that was attached to her sister. Suddenly, right after the slash appeared, Nyx's eyes slowly opened.

"Huh, what happened?" Nyx muttered out as she slowly sat up and looked around confused. "Why is everyone sleeping?" 

Her eyes then landed on her demon slayer friends and she got confused. "What, hey." She got up and walked over to Rengoku, placing her hands on his shoulders, shaking him, trying to wake him up. "This isn't the time to be sleeping." This didn't work and it caused her to frown with worry. She could feel the cursed energy wrap around her soul, providing her comfort as she looked around.

She noticed how everyone on the train was sleeping, but she also noticed the children attached to her friends by ropes. Her eyes then landed on the boy that was badly hurt. "Oh, hey! Are you okay?!" She asked as she rushed over to the boy. 

He cringed in pain as he slowly opened his eyes. The moment he saw Nyx, he began to freak out, screaming as if he was being killed, trying to back away from her. "No stay away you monster!" He shouts and Nyx paused as she looked at him confused. The boy got up and took off running down the aisle. 

Nyx stood there for a moment, in confusion, before she stood up and looked around the train. She could sense the energy of a demon, but it was coming from all over the train, so it made it hard for her to pinpoint the demon's location. She turned around and saw Nezuko, but she couldn't see Rui, which worried her.

"Nezuko...where is my son?" She asked and Nezuko shrugged her shoulders. Both girls heard a quiet groan, and they looked over at their brother, to see tears roll down his face.

They frowned in worry, before Nyx gritted her teeth and clenched her fists in anger. "Nezuko, you stay here and protect them." She told her sister and Nezuko looked at her worried. Nyx grabbed her sword, closing her eyes, trying to focus on the demon's energy.

"You can do this, Siren." She heard the voice inside her head stay, so she focused on the demon's energy and strained her ears to listen for any signs of movement.

She could hear some humans moving around in the next cart over, but they weren't who she was looking for. Soon she felt it, the dark and musky energy that she normally feels on demons.

Her eyes snapped opened, to reveal her eyes were glowing. She then jumped out an open window, which shocked and worried her sister.

On the roof of the train, Enmu stood there, his clothing whipping around due to the harsh wind. Soon a fond smile spread across his face, as he could sense Rui's presence behind him.

"Oh, have you finally come up here to play with me...Lower Moon Five?" Enmu asked as he turned slowly to face Rui, his amusement shining in his eyes.

"You..." Rui growled out as he glared at the demon before him. "What have you done to my mother?" He asked as he collected some webs on his hands, trying to act threating to the demon before him.

"Oh, you are adorable when mad, Rui!" Enmu said in a teasing tone, which annoyed Rui further. "Don't worry, your captures are happily dreaming right now!" Emnu purred, his hands clasping together and pressing against his cheek as he cooed.

Rui frowned, not liking how this demon was accusing his mother of kidnapping him. "I wasn't kidnapped." He growls out and the demon looked at him shocked.

"Wait, are you telling me...you went with the demon slayers...willing?" Emnu asked and Rui glared at him. "So, you betrayed Master Muzan!? Why!?" He shouts in anger, not understanding why Rui, the most loyalist to Muzan, would betray him.
