(THIS IS MODERN AU, DEMON'S STILL EXIST!) You work for the police department, you're a special class policeman/woman where your mission is to capture demons and lock them in cells that are surrounded by Wisteria!
You were working late at night, per usual. And you happened to spot a wanted demon.. Douma, Uppermoon 2! You knew he was going to be dangerous so you threw a kunai at his leg which made him stumble and fall, failing to pull it out you handcuff him, threw him in your cop car and made sure to restrain him in the seat.
Fast forward to when it was time to take his mugshot, you threw him in there and gave him his placard, he held it in one hand and looked at you, smiling before you took the picture of Douma's mugshot he said; "Guilty as charged for being handsome~!" You took the photo and sighed, grabbing Douma and tossing him in his cell, making sure Wisteria was still surrounding his cell.
