Today everyone was getting ready for vacation in the human world and while everyone was getting ready Asmo went to check on Lucifer and found him in his office sitting at his desk looking at a picture of Mammon.

Asmo : you ok?"

Lucifer : ...... it's  six years almost seven and we still can't find him....."

Asmo : can't believe he felt this bad about what happened"

Lucifer : I said horrible things to him ....things I know that are the reason he left....."

Asmo : what did you say to him?"

Lucifer :....I made him believe I hated him that I didn't trust him....that we we're not brothers anymore.....I said so many things I didn't mean....if I was only thinking straight he wouldn't have left....."

Asmo : .....that would do it. I'm sure we'll find him. And when we do you guys can talk it out"

Lucifer : ....I feel like I've already lost my chance.....that I made us lose another brother"

Asmo : well.... I'm sure Mammon is fine wherever he is. Probably living in his car somewhere since that's the only thing he took. If he still has it"

Lucifer : ..... anyway is everyone ready?"

Asmo : yeah just waiting for you big brother....also what you told me am I suppose to keep quiet about it o-

Lucifer : I would like if you did for now. I don't want to ruin everyone's time "

Asmo : got it"

After this Asmo walked away and Lucifer then stood up from his desk and left. 

Later everyone left and were in the human world now and got to the house they were going to be staying at for a bit.

And as soon as everyone walked in they quickly left to pick out their rooms but Lucifer stood back and thought about how he wished Mammon could be with them.

He knew his brothers felt the same way they missed him constantly and knew they would hate him if they knew what he said.

But Asmo didn't and reacted better than he thought. But realized he probably also didn't want to ruin the trip and was most likely pretending not to act mad with him.

Anyway since Mammon left they checked all over Devildom and also the human world but since it was so big. Lucifer would personally whenever he had time search for Mammon and each vacation they would always take a trip to the human world hoping to run into him.

It wasn't the same without Mammon.

Later after everyone was settled in they all decided to take a walk to the stores nearby since they were so close.

And everyone seem to be happy for the most part. Talking about what they were going to buy and eat.

And as they were walking they were passing by a kindergarten and Lucifer looked over seeing parents drop off their kids and during this he suddenly stop which made everyone else stop.

MC : Lucifer what is it?"

Lucifer : his car...."

Everyone looked and saw his car parked outside the kindergarten and then spotted a white hair guy kneeling down and talking to a little girl and they knew that voice and look anywhere.

Mammon : you do a good job today ok kid?"

Lucy : ok daddy! Love you!"

After this she hugged him then ran inside the school. Then Mammon stood up and started walking back to his car until he felt eyes on him.

He then looked over and immediately saw everyone looking at him.
