Dunt Boukon's original home was in another world full of demons of many different shape and sizes of how they look and what they do. Dunt's place there was just to mess with other demons there. Dunt is one of a few very rare Demon's there who aren't able to die so easily by stabbing, exploding, getting shot, etc. The only way he can die is by getting attack constantly by holy type items which there are luckily none in this sort of world. Anyways, Dunt's original job was to deliver human items to the god/king of this world when he does find them out on the streets in the area but in one day, Dunt decided that he wanted to pull a prank on this leader of the demon's. Dunt placed a fake mock up of a cross inside of a box to give it to the lord of the demon's to see his reaction to it. Once he gotten into the palace of the demon's of where the lord of the demons are at. Dunt gave him the gift and quickly hide behind a pillar. The demon lord open up the gift and quickly froze in shock to see the fake cross in it thinking he was about to die but in further expecting it. He soon realize that it was a fake and quickly grab Dunt behind the pillar and drop him in front of his seat.

The lord instantly started to yell at Dunt for pulling off a terrible prank like that and decided to put him into the human world as punishment for pulling a crime like that with no way of getting back to his home world. The demon lord put Dunt's butt in the air and gave him a good kick through the portal and closing it behind Dunt in no way of getting back. Dunt gotten back up and saw that he is inside of a forest somewhere. Without even taking a step, a lady went up to him pointing a gun at him immediately asking if he is a demon. Dunt confused told her that he is infact of a demon and without hesitation, she quickly shoot Dunt in the stomach to test that fact out. Dunt looked at her confused and then she started to act all nice to him by calling him a cutie, and handsome. Her name is Solar and is asking Dunt if he wants to live with her. Knowing that Dunt basically don't have anywhere to live right now so he accepted her offer. Solar gave him a smiling while shooting him a second time and by grabbing him by the arm to quickly ran back to her place. While running back, she told him that she been wanting a demon for some time hearing about them being able to easily take care of a ghost. Dunt being confused about this fact just accepted that he can take down a ghost without a sweat while he tries to cover up the holes that Solar gave to him.

Solar burst through her own door then quickly locking it and threw Dunt onto the couch and explained everything about Luna to him and about her wanting that ghost's harp. After explaining all of that to Dunt without giving him a chance to speak, she than told him that he is now living with her for now on and then grabbed him by the hand to the upstairs room next to hers and threw him onto the bed telling him to be comfty there on his new home. Dunt looked around his new room and he sort of likes it here and decided that he will stay with that crazy girl for now on. A few days has passed in his new home while Solar somewhat abuses him with bullets, he decided to find a job somewhere that will suit him well for getting used to this new human world. While looking around, he found a mailing service that he might find fun.

When Dunt enter the room for his review, the owner decided to quickly hire him for the job right off the bat knowing that he is a demon and can easily take on the super risky mailing jobs that he will be doing. Dunt shock but happy, shake hands with him and quickly went off to deliver mail knowing that he can easily mess with people by telling them what inside of the package by leaving a smerky comment about it. Solar does not like him having a job but she can't really do much knowing that Dunt can easily take her on if she does get on his bad side too much.
