The reason they had to was Because this was a special dance they had to do as kings of Devildom Under the blood moon that shine down in the center of the ballroom that they were under.

Despite their conflicting emotions Mammon put his arms around Diavolo's shoulders and Diavolo put his arms around Mammon's waist and they started dancing as the music played.

Diavolo looked at Mammon. Who was looking away still seeming very angry and could see him holding back tears as his eyes seemed so glossy and some tears were streaming down his face.

Diavolo couldn't bare to see this he felt like a true monster. He couldn't look at Mammon crying being in so much pain being so unhappy.

So he stop and took Mammon by the hand and immediately ran off with him out of the place and of course reporters and others followed wondering what was going on.

Mammon : what are you doing!? Where are you going!?"

Diavolo : I Don't know! But trust me!"

Diavolo continued to run with Mammon and Mammon was really confused now but still angry. And looked back and saw reporters following them.

Mammon : damn they Don't stop!...."

Diavolo : .....I know where we could go. I know you have no reason to trust me. But can you trust me this once!"

Mammon : Don't i even have a choice!?"

Diavolo : of course you do. You always have a choice!"

Mammon : ...... fine.... anything to get away from these guys!"

Diavolo : good. Get ready to jump!"

Mammon : f- WAIT WHAT!?"
