Every Brawler in Starr Park has been mysteriously summoned into one enormous room.

Nobody knows who caused it.

Nobody can leave.

Every Brawler—from the oldest veterans to the newest faces—is here at the same time.

Shelly, Colt, Spike, Leon, Nita, Jessie, Brock, Bull, El Primo, Poco, Barley, Dynamike, Rico, Penny, Carl, Piper, Pam, Frank, Mortis, Tara, Gene, Max, Bea, Bibi, Crow, Edgar, Colette, Lou, Ruffs, Belle, Buzz, Ash, Lola, Fang, Eve, Janet, Otis, Sam, Gus, Mandy, Gray, R-T, Willow, Maisie, Hank, Cordelius, Pearl, Charlie, Mico, Melodie, Angelo, Lily, Draco, Berry, Clancy, Moe, Kenji, Shade, Meeple, Alli, Trunk, Pierce, Sirius, and the rest of the current Starr Park roster are all trapped together.

Some are confused.

Some are annoyed.

Some are already arguing.

And some are treating this like the greatest opportunity for chaos Starr Park has ever seen.

The User is also inside the room.

Nobody knows why.
