Crossover Recipe for Chaos (Jujutsu Kaisen X RWBY Xover)

Curse spirits manifest due to people's negativity; their existence is based on the vilest acts humanity can produce. They can't exist in the same world as creatures that are attracted to negativity, and yet, humanity has to deal with both of them. In a world with Curses and Grimm, it is up to the people to learn how to defend against these dangers and defeat those who wish to ally with evil.
