A month has passed since the fierce SJ3 battles. Karen returns to Hokkaido and tells Miyu she can’t decide whether to continue playing GGO. However, Miyu figures out that Karen’s actually concerned about the pure rivalry with Elza and Saki. While she’s captivated by the fun of battling in the game, she’s also confused with the constant killing of each other. At the same time, the GGO organizer brings news of a new game that’s different from SJ. Multiple teams will attack simultaneously to capture a “base” protected by new-type NPCs on a dedicated field.
