Unexpectedly, the Upper Moons were summoned yet again to the Infinite Fortress. Everyone was confused, until a loud explosion came from one of the rooms.

A girl with (H/C) hair came flying out of the room.

She had a nirichin sword, indicating she was a demon slayer. Her haori was wrapped around her waist, while her uniform was covered with blood.

What made it all intimidating, was her aura. The (H/C) haired female’s aura was one of the strongest auras the Upper Moons ever scensed. It almost scared them.

Doma’s eyes widened, as he watched (Y/N) struggle to stand up. Both their eyes met, but before (Y/N) could speak, I foot shoved her back on the floor.

"It amuses me how you’re still going." A dark and deep voice said.

(Y/N) gripped her sword and turned around. She sliced Muzan’s leg off, giving her a chance to stand up. She looked dead right at the red eyed demon. Unfortunately, Muzan's leg regenerated quickly.

(Y/N) unleashed her sword and started running towards Muzan. "KIBUTSUJI! YOU SHALL PAY!" (Y/N) yelled, aiming for Muzan’s neck. "Gem breathing! 10th form! Diamond Unbreakable!"

Her eyes widened, feeling a grip on her neck. (Y/N) dropped her sword, as she tried to get out of Muzan’s hold.

Doma watched (Y/N) struggle. He tried to move, but it was no use. He was frozen.

Muzan tightened his grip around the poor Hashira's neck. Her struggles only made this more amusing for him.

The red eyed demon jabbed (Y/N)’s sides, making her fall down to the ground.

Seeing this made Doma snap out. "(Y/N)!"

"Restrict him." Muzan ordered the other Upper Moons. Doma tried to rush over to (Y/N), before he was stopped by his fellow comrades.

"(Y/N)-chan-"

"Control yourself!" Akaza yelled. But the blonde demon kept resisting.

Muzan and (Y/N) looked at each other, before Muzan stopped his foot on her stomach. (Y/N) coughed up blood, as Muzan repeatedly stomped on her.

"It’s a pure mystery how you're still alive." Muzan said, stomping harder. "But I guess I was a bit too soft on you."

(Y/N) was covered in her own blood. Her vision was starting to blur, but she knew she had to stay focused. She shakily sat up, rage could clearly be seen in her eyes.

"Pathetic." Muzan spat, as he unleashed his long and sharp nails. "Let’s see if the heavens will give you another chance."

(Y/N) waited for the pain to hit her, but that never came.

Arms snaked around her head, as a loud crunch was heard. Blood dripped on the Hashira's forehead. She slowly looked up at the figure that had shielded her.

"Ara, Ara~ You’re sometimes reckless, my diligent wife." the blonde demon said, blood dripping from his mouth. "I’m sorry, (Y/N)-chan."

(Y/N)'s lip quivered at the sight. She saw a big gush on Doma’s back. The gush was so deep, that it opened up the blonde demon’s stomach.

Muzan looked at the Upper Moon with disappointment. The other demon’s mouths were all agaped.

"What an idiot." Muzan sourly insulted, catching everyone’s attention. "Unfortunately, Doma is still a valid asset. Meaning, he will still be part of the Upper Moons."

The red eyed demon looked at the (H/C) haired female, and glared at her. "As for you."

"Tch, what?" (Y/N) spat.

"I'll kill you later." After the demon progenitor said that, a strum was heard and Muzan disappeared.
