Later they arrived at the carnival where there were guards everywhere questioning people while Diavolo was standing with Kammon trying to calm her down as she was crying.

During this MC walked over to her and and decided to take her away from the situation while everyone else talked about this.

Levi : why would someone kidnap him?"

Barbatos : Diavolo does have his fair share of enemies. What about Mammon?"

Satan : it's Mammon we're talking about? "

Asmo : yeah but didn't all his debts get paid off?"

Beel : maybe someone wants more?"

Barbatos : yes. But it has to be someone who would dare to try something like this. This is considered a serious crime"

Satan : and probably death. Lucifer looks ready to kill which should be a fun show"

Diavolo : hmm it could be one of my old connections. Things ended on a bad note. And he did say he would get revenge on me"

Barbatos : but we never took his threat seriously....which was our mistake"

Lucifer : where does he live?"

Diavolo : a-!?

Diavolo then flinch in pain and put his hand on his chest as he felt this immense pain rush through him like he was kicked in the chest. He was also gasping for air for a few seconds.

Barbatos : are you alright!?"

Diavolo then started coughing and ended up spitting out some blood. And Lucifer looked worried.

Lucifer : .....Barbatos...."

Barbatos : Whoever has Mammon must be hurting him. Like I told Lucifer they can feel each other emotional and physical pain"

Belphie : at least we'll know if he dies?"

Barbatos : ....your not wrong.... anyway we have to be careful. He could be expecting us to go to his home. Which Mammon is most likely being held at. "

Asmo : will this guy really try and kill him!?"

Barbatos : ......we have to assume the worst...."

Satan : would there be a way for us to sneak in?"

Barbatos : maybe"

Diavolo : or I could give in to his demands..."

Barbatos : there's no saying he'll give him back if you do so"

Satan : he's right in these situations it's always a lie"

Diavolo : ....we will get him back....a... anyway I doubt he would take Mammon to his home..."

Barbatos : yes....you could be right. But we'll send guards over there anyway"

Diavolo :...I am terribly sorry....I should of done something back then....."

Lucifer : yes you should of. But let's focus on saving Mammon"

A few hours later....................................

Everyone was looking everywhere for Mammon but still couldn't find him no matter what. Demons were questioned nobody saw anything or knew anything guards kept coming back with nothing.

And eventually everyone met up together to talk about this and as they did Diavolo suddenly got a phone call and he answered it and said Trying to sound serious and calm. Like he wasn't in an incredible amount of pain.

Diavolo : it has been awhile...."

Evil Guy : yes it has old friend. Quite insulted you didn't invite me to the wedding how rude of you"

Diavolo : ....where is Mammon?"

Evil Guy : he's right here. Still breathing but he does look awfully hurt. I wonder how much more he can take?"

Diavolo : ..... whatever you want I'll provide you...."

Evil Guy : is that so? You must really care about him. How pathetic"

Diavolo : now what do you want?"

Evil Guy : step down down as king and give the crown to me"

Diavolo : ...... you know I cannot do such a thing"

Evil Guy : so I guess I'll just kill him. He must not mean anything to you "

Diavolo : I...-!?

Evil Guy : you have 30 minutes to decide"

The guy then hung up and Diavolo was the sent a picture. He looked at it

And saw it was a picture of Mammon in some dark room barely conscious as he was laying on the ground badly hurt and wounded his wrists and ankles chain to the wall. 

Barbatos : what is he asking of you?"

Diavolo :....to step down as king and give him the crown....or he kills Mammon....I have 30 minutes to decide...."

Lucifer : what are you going to do?"

Diavolo : .......I.....I... what he's asking I cannot give but I also can't allow Mammon to be killed....."

Barbatos : he's doing this Because he knows it's a impossible choice"

Beel : but he can't let our brother die...."

Diavolo : I Don't intend to.....I'll think of something.....if this is what he wants I have no choice. But to do what he wants"

Barbatos : Lord Diavolo y-

Diavolo : go get the crown. "

Lucifer : i-

Diavolo : I have a plan"

Barbatos : ok"

Later the guy called back. and Diavolo made his choice and now Diavolo was going to meet guy at the place he was holding Mammon. alone with no back up like the guy said.

He knew very well this was a trap but went anyway with his crown. Everyone was on standby far enough away the guy wouldn't suspect but also far enough away if there was trouble they would be late. But at least they would come.

The plan was for them to wait 10 to 15  minutes before coming. By then Diavolo figured he would have the guy down or dead.

This one Guy was real bad a threat he should of took more seriously but didn't and Because of that Mammon was going through pain that could of been avoided.

Anyway he arrived at some old abandoned mansion and saw the door wide open. He knew this was bad but walked in and started following this blood trail.

Which made him incredibly worried knowing this was most likely Mammon's blood.

Anyway he ended up going down to a dungeon that took him to one room.

And there on the floor like in the picture was Mammon. Who was awake now but very weak and hurt but tried sitting up.

Diavolo : Ma-!?

Mammon : Diavolo!"

Mammon then collapsed back on the floor in pain. And Diavolo looked down and saw a knife sticking out of his chest that went through his his back going right through him.

The Guy that was behind him then pulled out the knife and Diavolo fell to his knees as blood started leaking out of his mouth.

He felt paralyzed like he couldn't move at all no matter how desperately he tried.

Evil Guy : should of paid more attention now look what happened.  You know this is a special knife one of the few weapons that can do damage to you even kill you."

The Guy then walked over to the front of Diavolo and Diavolo said trying to push through his pain.

Diavolo : ....k ..kill me....if you will....but let him go....."

Evil Guy : how sweet your still so focus on him and not yourself"

The Guy then walked over to Mammon and said holding up the knife.

Evil Guy : watching him die. While your force to watch now that sounds g-!?

Before the guy could kill Mammon. Diavolo  manage to get up you'll the guy away from Mammon throwing them against the wall. And with that They both started fighting each other.

Diavolo was very weak  each time he moved his wound got worse and bled out more. It didn't help that the Guy still had the knife and was slashing at him with it and stabbing him.

Eventually it was to much and Diavolo was back up into a corner to weak to fight him anymore. And the guy  was about to kill Diavolo. Raising the knife up.

And in the split second Diavolo looked at Mammon. He made a promise and no matter what he intended to keep that promise.

He got strength back and immediately grabbed the Guy's hand that was holding the knife and pushed it into the Guy's chest making him stab himself. Which killed him immediately.

After this despite badly wounded He got Mammon free and picked up Mammon  and carried him out of the place where they met up with everyone.

And were rush back to the Castle Diavolo still carrying Mammon not taking his eyes off him.
