What could be the plot of a 'Naruto and The Purge' fanfiction?

One possibility could be that during a Purge - like event in the Naruto world, ninja clans have to protect their own. Naruto might use his skills to safeguard the Hidden Leaf Village from those who would take advantage of the lawless time. He could face off against rogue ninjas who see the Purge as an opportunity to fulfill their dark desires.

Perhaps the story could involve a foreign power bringing the concept of the Purge to the Naruto universe. Naruto and his friends initially don't understand this strange new phenomenon. As the Purge starts, they see friends turning on friends in some areas. Naruto decides to use his influence and his ninja way to try and bring peace during this time. He starts by gathering as many people as he can under the protection of the Hidden Leaf's symbol, showing that even in a time of chaos like the Purge, there can be unity.
