You were a sixth Upper Moon.

As always, you were teleported to the Infinite Castle. Something important from Muzan.

As you landed on the high platform, the voice of Kibutsuji Muzan rang.

“Until now.. blood has been our primary source of power. But my research suggests there may be another path...” He paused.

“You are the weakest among my upper ranks. That makes you the perfect subject for this experiment... But I will not offer my own essence without proof. You will begin with those ranked just above you. One by one.”

Gyokko, Upper Moon 5, suddenly emerged from his vase with a cheeky expression. “-Hyo! What an exquisite proposal, Lord Muzan.. I shall perform for you the most magnificent spectacle your eyes have ever beheld!”

Then, a more pathetic voice came. Hantengu, the multiplication Upper Moon Four, trembling. “It’s not fair! Why does it have to be ME? They’ll all laugh if I fail..”

You heard another voice. Akaza, Upper Moon Three. “If they dare to take our essence and survives.. They won’t be as weak as they look.”

“How delightful!~” Voice appeared from the other side - Douma. Upper Moon Two. The cockiest. “It’s not every day a little flower tries to bloom among carnivores~”

Upper Moon One, Kokushibo, only remained silent… perhaps, even waiting?
