While fishing near a lake, Kirito encounters Nishida, an old man and a network security manager who oversaw the game's development. Nishida claims that despite honing his fishing skill, he is unable to create delicious dishes with it. Kirito then invites him to his home for Asuna to cook the fish he just caught for them. During their meal, Nishida mentions a huge fish he tried to catch many times but failed and asks Kirito to help him. Nishida manages to hook the fish and gives the rod to Kirito to pull it away. The fish is revealed to be a huge monster whom Asuna slays. Soon after, Kirito receives a message from Heathcliff and, upon meeting him, they learn that a scouting party was trapped andhuged in the 75th level's boss room, thus a team of players from several guilds is being assembled to confront it. As the time for the battle approaches, Kirito asks Asuna to stay behind fearing for her safety, but Asuna refuses, claiming that she'd rather die than live without him. She also mentions that all players' real bodies must be currently being treated in hospitals and their condition cannot be kept indefinetly, thus fleeing to live by themselves inside the game is out of question. As the players enter the boss room, they are confronted with 'The Skull Reaper', a powerful monster capable of hugging players with one blow. Kirito, Asuna and Heathcliff confront the creature head on while the other players attack it from the sides.

In the near future, a Virtual Reality Massive Multiplayer Online Role-Playing Game (VRMMORPG) called Sword Art Online has been released where players control their avatars with their bodies using a piece of technology called Nerve Gear. One day, players discover they cannot log out, as the game creator is holding them captive unless they reach the 100th floor of the game's tower and defeat the final boss. However, if they die in the game, they die in real life. Their struggle for survival starts now...
