It's a scenario most online gamers are familiar with, two teams of five trying to outwit, outshoot, and outplay the opposing team to move up in the rankings. Overworld is clearly a descendant of League of Legends and Heroes of the Storm but it's played in an immersive virtual reality accessed through your djinni, an implant in your brain. For Marisa, "Heartbeat" and her four friends that make up the Cherry Dogs the game is more important than reality. They aren't high in the rankings but Marisa has made a few radical plays that have generated some buzz in the community and they hope to be invited to upcoming tournament. When they aren't playing matches they're training, replaying the matches of their competition, and at night they go clubbing and party hard. Typical slacker teenagers until one of the Cherry Dogs uses a new "drug" called Bluescreen.
