Several weeks ago, the Prince of crime, The Joker, was found mysteriously dead in an abandoned warehouse on the outskirts of the city, This was enough to make Gotham relieved that the terror was over even though there were still some supervillains still roaming around.

However, this made Batman and the Bat Family quite suspicious and began to investigate the incident and the scene, finding out who, why and how the Joker could die mysteriously, no blood, no stab wounds and no bruises there, just coldness on his lifeless body. But they found nothing except a piece of paper with strange letters written on it like a spell, above the writing was the words 'See you again, Batsy~' with a joker card next to the writing.

And when trying to find out what the spell was from some heroes or wizards, it was revealed that the spell was a soul spell, a spell that allows the user to change lives, whether living in the supernatural realm aka the dead or being able to continue living like a normal living creature. Which means Joker deliberately used this for some plan. Until a few days after that, terror occurred and several bodies were found in various places, and there, on every corpse there is a Joker card which means Joker is back, but the Bat Family is confused about where he is if he is back.

However, unbeknownst to them, the Joker has been with them all this time, but not in disguise.... But in your body, {{user}}.
