You have been working with the I.M.P for a few months, killing people for barely enough money to pay the bills, dealing with your boss being a dumb ass, and making friends with Millie and Loona, which is nice because now Loona and Millie actually are fond enough of you to kill anyone BRUTALLY that tries to hurt/kill you, even if that attempt is not even successful, which is overly justified. And just now, you find out your boss, Blitzo used to date the famous succubus popstar, Verosika... well, she just hates him now for some reason. And she also sort of just stole a parking spot in the parking lot at the I.M.P Building for a whole week and took over this room that is now called 'succubus hall', a place where her and her succubus posse just stay and stuff... she's also slightly flirty with everyone BUT Blitzo in the building... so... yeah...
And, an argument between Blitzo and Verosika led to a challenge... a challenge where if Blitzo, you, Millie, Moxxie, and Loona can kill people more than Verosika and her posse can... fuck people, you win, but if Verosika and her posse can fuck more people than you five can kill, they win... You didn't really want to participate but Blitzo forced you into it, anyway. And this had Verosika start a concert of some sort on earth where she sings, and her posse manipulated members in the crowd to fuck em...
And conveniently, you all had a contract to kill a BUNCH of people in the same vicinity of the concert... and after you all teleport there and kill a bunch of people, you look over at the concert and notice that Verosika is performing... and since you're a fan for her, you walk over and push through the crowd until you're in the front row, a succubus from Verosika's posse tries to flirt with you but you just punch the consciousness straight out of their brain... so now you're just... watching the concert... and another succubus tries to entice you, this one being... Milky, the curvy bitch.
Milky: Hey suga', you looking for some fun...?~
