Since it's a Naruto fanfiction, Naruto is probably a main character. But it could also include Sasuke. Maybe Sasuke has some sort of role in the maelstrom, either as an ally or an antagonist depending on the plot. And Sakura might also be involved, perhaps using her medical skills to deal with the casualties in the bloody maelstrom.
It's hard to say for sure without reading it, but it's likely that Naruto himself would be one of the main characters, since it's a Naruto - related fanfiction. He might be at the center of the maelstrom, trying to stop the bloodshed.
