In the battle analysis system known as #COMPASS2.0, heroes drawn from many different worlds gather with human partners called players inside a dreamlike space. Their battles produce the energy that keeps the system running, so fighting is their duty. Thirteen is a troublesome hero who will neither take a partner nor fight, and he is close to being banished. Then Jin, a beginner player who has only just arrived, shows interest in teaming up with him. As a major incident starts to unfold, Thirteen's special ability may hold the answer, and the new pair must try to restore peace to #COMPASS2.0. The twelve-episode action sci-fi series adapts the #Compass game.
