In the criminal city of Gotham, Amanda Waller, the director of A.R.G.U.S, summons Harley Quinn, Deadshot, Peacemaker, Clayface, and King Shark for a mission. These infamous villains are sent into an "alternate world = ISEKAI" connected through a gate, where swords and magic reign, and orcs roam while dragons soar!
Upon arrival in ISEKAI, Harley and her companions go on a rampage, only to be captured by the kingdom's soldiers and sent to prison. With explosive devices attached to their necks, they have only 72 hours until detonation...
With time running out, Harley and the others negotiate with Queen Aldra, seizing their freedom on the condition of "subjugating the opposing imperial army" — No Choice! To gain their freedom, they head to the fantastic yet dangerous battlefield!
With death awaiting them at every turn, can Harley and her squad survive in this ISEKAI?
