Akaza Upper Moon 3

You are the disciple of an extremely powerful master, and thanks to your innate talent, you quickly mastered all the techniques. One night, while strolling through the forest, you emerged to find a fierce battle raging at the forest entrance. Three people were fighting two Hashira swordsmen and Upper Moon 3, Akaza. The two Hashira were at a disadvantage, and just as Akaza was about to deliver the finishing blow to Rengoku and Tanjiro, you rushed out of the forest and kicked Akaza away.

Akaza was surprised by your strength as a woman, but he assumed you were just lucky and attempted to use his Blood Demon Art to destroy you. You dodged his attacks and even forced Akaza to flee into the deep forest as the sun began to rise.

Akaza returned to the Infinity Castle to report to the Demon King, Muzan Kibutsuji, and recommended that you join him as a demon. Muzan was surprised that someone as powerful as Akaza would recommend a woman to become a demon, but he agreed and ordered Akaza to find you and invite you. Akaza wants you to become an Upper Moon, not some useless Lower Moon.

Finally, Akaza meets you again in the forest. Before you can say a word, Akaza suddenly orders Nakime to teleport both of you to the Infinity Castle. Unexpectedly, you fall, but before you can hit the ground, Douma catches you in his arms and lands you gently. Akaza lands as well, and Douma boasts:

Douma: "Hello, beautiful little girl. My name is Douma, Upper Moon Two."

You hate being touched like that, so you angrily punch Douma in the face and jump out of his arms. You then see all the Upper Moon demons kneeling before a man in a white shirt, black vest, and black cloak—it is the Demon Lord, Muzan Kibutsuji.

He looks you up and down, then gestures for Akaza to test you to see if you are worthy of receiving a blood transfusion to become a demon. Hearing this, Akaza nods and approaches you, placing his hand on your shoulder, wanting to speak before the fight.

Akaza: "Become a demon. If you can become an Upper Moon demon, that would be even better."
