The Antagonist successfully completed his "crusade" in New York… but even after that, he cannot find peace. Reborn in Hell as a newly minted sinner demon, he must now make his way through capital Pentagram City. It's time for him to kill… and it's time for him to die… again (at least, try to).

Murder. The main thing that unites both hell and heaven. Both sides of the conflict have been hurting each other for too long. Vox didn't lose, it was his backup plan. The explosion of Hell is just the tip. No one could have expected that Vox had scattered a bunch of bombs all over Pentagram City. After his "defeat", he took control of all the bombs at one time, and committed a terrorist act. Those who were at the epicenter are dead. Alastor managed to survive, though not completely. Heaven does

Things are not going well at I.M.P., a company that specializes in killing people. There are no clients, no money, and Blitz is seriously thinking that they are about to end, when suddenly a very aggressive client named Roxy bursts into their office and offers to kill the kid who sent her to hell for a lot of money. It would seem that this is the solution to all their problems, but Roxy has one condition - this order must be performed by someone who looks like her. And that's Loona.

«Big talk for someone who is also in the leash!» – Husk's phrase plays over and over in Alastor's head when he looks into Charlie's tear-stained eyes, who needed comfort after returning from Paradise, but the Radio Demon desperately pushes this thought deeper into his mind, denying it.

Milady, I am sure that when the one who is undoubtedly dear to you and who now hugs me so trustingly is finally in my arms, it will be my turn to pull the strings. It's not as simple as you think, but for now... In a fit of momentary weakness, my lips touch the blond crown, inhaling a sweet aroma, from which my eyes blissfully close on their own. The main thing is not to get too carried away...

Drowning in love, give me the last dance, dear...

Drowning in love, you don't notice anything. Just dance with me without knowing that this is the end. Just give me this feeling of happiness at last. After all, I will leave, saving you. But there is no need to shed bitter tears. I will try to come back and bring back our happiness. How many years will it take? Ten? Twenty? Or a hundred? I don't know this for sure. But just wait for me, darling. Wait, remembering the last time you and I danced...
