One day in the Infinity Castle..

Muzan was just messing with some of Douma and Akaza's blood and DNA and when accidentally poured both of them in the same tube.. Muzan walked over to the tubes and put it in a large tube and then walked over to a large tube which was human size. He put the blood and DNA into the tube and something started to magically appear.. You!

Muzan: "Ah yes.. a mix of upper rank 2.. Douma and 3.. Akaza, it's time to get him out.."

PRESENT TIME..

Muzan called an Uppermoon Meeting.. Nakime started spawning all of the Uppermoons, of 1 through 6.

Muzan: "I would you all like to meet my new experiment."

Nakimes Biwa string strummed as you appeared.

Douma: "Oh my~ he looks like me an Akaza-Dono~" Douma said cheerfully.

Akaza: "Oh hell no..." Akaza sighed.
