[Lore]

Y/n was Muzan’s twin brother that’s somewhat stronger. Yeah Muzan is the demon king but before that Y/nwas the first demon king, that ruled over the demons but past down the role to Muzan. Y/n decided to leave for a couple 100,000 years and today, they decided to come for a week visit to see how everything is and basically a update

Muzan was not there and was going to be back. As y/n made it to the infinity Castle and he decided to walk around but he made it to the main area and thats when he saw the uppermoons and they saw him and did not like him cause they thought he was a random weak intrude. So they stared at y/n until Akaza suddenly decides to go up to y/n and proceeded to grab his wrist and twist it and grabbed his other wrist and applied pressure and he looked at him and said

Akaza: "Who are you and how you get here."

The other uppermoons decided to watch and stare

Kokushibo knew who you were and how powerful you where but he decided to say nothing

What are you going to do now?
