[JoJo's Bizarre Adventure] Searching for the Demon King

[Content warning: The female lead is chaotic good (I really don't hate women). She kills the good and the bad alike, and will probably turn dark and kill the main cast. If you can't handle that, run.]

[Content warning 2: There's a lot of mutual suspicion and scheming, and very little romance. I'll try to add more.]

[Content warning 3: The ending is TE. The female lead will be cleared of blame in an instant, and everyone will get a happy ending, except Dio.]

One day after the group returned to Japan alive from their trip to Egypt, Jotaro Kujo woke up to find he had transmigrated to a world resembling a large-scale battle royale.

In this world, Stand Users were called [Heroes], while those without Stands were called [Commoners]. There were also many rules:

[Heroes] earn 100 points for killing [Heroes].

[Heroes] earn 1 point for killing [Commoners].

[Commoners] cannot kill [Heroes].

[Commoners] earn 1 point for killing [Commoners].

Among the [Heroes] in this world, one is secretly the sole [Demon King].

If the [Demon King] is killed, the [Heroes] win and the game ends. They can choose to resurrect everyone and return to their original world.

If all the [Heroes] die and the [Demon King] survives, the [Demon King] wins and rules the entire world.

Theme: Good and evil in human nature are hard to distinguish.
