A thunderstorm rolled outside as Rella packed her things in the palace. Prince Zenitsu entered and was alarmed.

"Rella!" Zenitsu grabbed her hands." What are you doing?"

Rella paused. "I thought you were hunting."

"I was, but the weather wasn't agreeing so we came back early." Zenitsu let her go. "Are we going somewhere? You're going somewhere."

"Something's happened." Rella admitted dreadfully.

Zenitsu was puzzled. "What?"

Hushed, Rella whispered. "I'm pregnant."

Zenitsu gasped. "Rella, that's wonderful. Why are you upset? This is what we wanted."

Rella gulped, and then said, all in a rush. "There's something else. When we met that night at the ball, it wasn't my Fairy Godmother who sent me. It was the Demon Lord Muzan. I made a deal with him for this life. I was stupid. I didn't understand the price of magic. So I promised him something."

Zenitsu was quiet a moment and then said hesitantly. "What did you promise him?"

Rella groaned. "He tricked me. I thought that he'd want our gold or jewels..."

"What was it?" Zenitsu asked, voice full of sorrow. Rella held her stomach. "Our baby?"

"I'm so sorry." Rella cried. "And now I'm gonna lose it all, my...my life, you."

"No. I don't care what that demon said." Zenitsu growled. "Magic may have brought us together but it didn't create this love."

"But!" Rella insisted. "But I made a deal. I can't break that. He's too powerful."

Zenitsu grinned darkly. "Then the answer is simple. We make another deal."

New Chapter

Rella and Zenitsu walked through the dwarve's mines.

"Why are we down here?" Rella said nervously.

"We need a place to keep him." Zenitsu said firmly.

"Muzan is the most dangerous man in all the realms. He needs his own special prison, so we converted the mines to hold him." Prince Tanjiro explained.

"But how will we get him here? He has eluded all forever." Rella asked desperately.

"His strength is also his weakness. His deals. He can't resist making them, and we already know who he wants to deal with next, you." Urokodaki said.

"We've sent word with one of Kanao's bluebirds. He's accepted a meeting with you. You're going to tell him that Doctor Tamayo heard something with his stethoscope, two heartbeats." Prince Tanjiro said.

"You're going to tell him it's twins." Zenitsu said.

"And if he wants both, which he will, you propose a new deal. Urokodaki... " Urokodaki opened a box containing a quill.

"A quill, I... I don't understand." Rella said.

"It's coated in Tamayo's Blood Demon Art." Urokodaki said. "Whoever signs with this will be frozen, their magic made impotent."

"All you must do is get him to sign the contract. RElla, this man is a scourge. You will be doing the entire land a service." Prince Tanjiro said.

"Should we even use magic? Isn't that what's has causing these problems to begin with? What if this magic also has a price?" Rella asked.

"Then I will pay it." Zenitsu said. "I will do whatever is needed to save you and our child."

"Let's go." Prince Tanjiro said.

They ventured further into the mine's and arrived at a cell.

"I hope you like it. A lot of blood went into it." Urokodaki said.

"You sure this will work?" Rella asked.

"Once he is in there he'll never get out. You'll be safe." Prince Tanjiro said.

"We can do this, Rella." Zenitsu assured.

"Okay. Let's get him."
