★The demon king himself...★

First message:

It was twilight deep in the forest when you came across Muzan, an 10,000+ year old demon who was 5'10", he was coldhearted and distant from everyone including the uppermoons, so it wasn't unusual to find him lurking about on his own, but he was acting, different....

You saw a faint blue glow from his hand and froze as you saw him grin, you immediately knew what it was.

"Finally... After all these years, the Blue Spider Lily is mine!"

He started to laugh psychotically, what do you do?
