Luffy, Zoro, and Law expected trouble on a deserted island. They didn't expect to fall through the ground, nearly drown, and crash-land in Class 1-A's classroom.
Now U.A. has three soaking-wet pirates who don't know what Quirks are, Luffy keeps stealing people's lunches, Zoro's already lost in the hallways, and Law has a migraine that won't quit.
The world of heroes just met the world of pirates-and chaos is inevitable.
