Sword Art Online Progressive Volume 4 (ソードアート・オンライン プログレッシブ 004, Sōdo Āto Onrain Puroguresshibu 004) is the fourth installment in the "Progressive" series, a reboot of the original Sword Art Online light novel series written by Kawahara Reki. This volume covers the events that took place while clearing the 5th Floor of Aincrad. It was released on December 10, 2015.

Part 1
Kirito and Asuna pondered about various recent events, including Morte's attempt at killing Kirito via a Duel on the 3rd Floor. They considered the possibility that Morte might have been the man in the black poncho, who incited the weapon upgrading scam on the 2nd Floor.

Part 2
After their conversation, both returned to the 5th Floor main city Karluin to the restaurant «Blink and Brink» and ate a buff item, allowing them to find relics and random bits of treasures more easily. Kirito stated that there had been a fair number of relic hunters during the beta period, and thus assumed that the two main guilds were most likely doing the same at the moment to bolster their war chests.

Part 3
With the support of the buff, they earned some cor and returned to the 4th Floor to receive their reward for their help in defending Yofel Castle.

Kirito decided to choose a new sword to replace his current one. His previous sword was damaged beyond repair, and the current sword, which he had snatched from a Forest Elf, was only able to receive one more upgrade and thus couldn't become strong enough anymore.

They met Agil, who explained that he was working as a merchant, and lent his boat to them, as their own gondola was moored at Yofel Castle at that time.

Part 4
Kirito and Asuna finished the quest, went back to the restaurant and started to wonder why the buff wasn't sold out, and why Argo's guide hadn't shown up yet. After they went to their rooms, Asuna spotted Kirito leaving, tailed him and tried to catch up when he entered the dungeon.

Part 5
She silently followed him down to the 2nd level, but fell down a trap door after she was being confronted by a ghost and dropped her rapier. This rapier was grabbed by a shrewman, thus Asuna hunted it to get it back. While Asuna was killing monsters in her way, she found a handwritten note with coordinates to a meeting place on the floor she currently was on. Asuna discovered the meeting place where she spotted Morte and a collaborator, who discussed how to get both main guilds to fight each other, indicating one of them planned to sweep through the dungeon during the new years day party. Asuna threw a paper she found earlier, causing a noise in order to attract another monster. The plan backfired, as it was the monster with her rapier and was killed by the collaborator who properly looted the rapier. Having heard some parts of the conversation, Kirito appeared and realized that the collaborator had Asuna's sword. As Morte and his partner prepared to fight him, Asuna yelled loudly and startled Morte's partner. Asuna had noticed he had a slight hand-eye-coordination issue, and due to her yell he dropped the rapier. Another monster grabbed it, but Asuna quickly killed it and regained her rapier. Morte and his partner considered how to deal with Asuna and Kirito, but Kirito grabbed Asuna and used Hiding to avoid the monsters Asuna's yell had gathered, thus the two villains ran away as they would be outmobbed otherwise. Kirito and Asuna took a break and she explained to him what happened, to which he told her she had done well.

Part 6
Argo and Asuna relaxed in a bath in an instance village after the events in the catacombs. Asuna commented on the Dark Elves' love for their baths, and Argo replied that of the Forest Elves had the habit of bringing out tons of food during their quest-line. Asuna wondered why Argo was in front of the dungeon boss room, where she and Kirito had found her less than an hour after the event with Morte. Argo explained that she had scouted the boss at the bottom of the catacombs. When she found out that it was a giant zombie unlike in the beta, she spent the whole day to figure out a solution to the lever puzzle which would help defeating the dungeon boss. The puzzle was so difficult Argo had to resort to a trial and error approach at some point. In the end, she found the solution to the puzzle, which would open the ceiling. The dungeon boss, weakened by the sunlight shining from the ceiling, was easily killed by some top players on the December 30, 2022.

Asuna worried about Argo's safety, but in an informal duel Argo showed off her exceptional agility and limited ability to walk on water. Argo told Asuna that she was a beta tester and thus it was her duty to support the players. Joining the frontline group might be safer, but the things she did were important to help clearing the game. Argo also told Asuna that the only reason, that Kirito didn't do similar risky things, was because of Asuna.

Part 7
Kirito reminisced about New Year's Eve with his family last year. With the current pace, he realized, they would be trapped inside the game for next New Year's Eve too, and probably even for the year after as well, assuming he didn't die before. After the death game started, he had been leveling up as much as he could, afraid that other players would surpass him in levels, which would give them an advancement he could not catch up on. But after the events in the catacombs, Kirito realized he had another motive for staying alive, to watch Asuna surpassing him one day and possibly leading a major guild. During his search for Argo in the catacombs, he had suddenly seen Asuna's HP bar dropping by about 10 percent. Kirito came to the conclusion she must have fallen down a trap door on the second level, and rushed down to the third level. Kirito overheard the conversation about a Chivalric Rapier + 5, and confronted Morte and his partner.

Argo left their party after the bath and Kirito and Asuna wondered how they could react to the plan of the ALS, and set up a meeting with Shivata, who led the New Year's event from the DKB's side to ask who was responsible for planning the party on the ALS side, as the party was initially planned to bring the two guilds together. Shivata was anxious at first how they had known about him and his partner in the ALS, but Kirito replied honestly he only knew of the joint event planning, though Asuna seemed to have realized something what Shivata was concerned about. Shivata messaged his partner, and a few minutes later a player outfitted with a full steel plate armor and a heavy armet helm joined their group. Though they still were in town, the helm's visor was closed, thus it was impossible to identify the face beneath.

When the player lifted the helmet off the head, Kirito was perplexed to see a girl. The girl called Liten was admiring Asuna, and told everything that happened since her recruitment to the ALS. Liten gained a full steel plate armor due to a glitch in the system which made it possible to mine ores for an unlimited amount, before the bug was fixed. Thanks to that armor, she was scouted by a member of the ALS. In a meeting about the boss strategy of the ALS, someone hinted that the boss of the fifth floor floor would drop something that would change the entire frontline situation. But no one knew what that was, until Kirito figured out that the fifth floor boss dropped a guild flag in the beta, giving the guild in question a buff to all their stats.

Part 8
Kirito and Asuna were eating Mananarena's specialty in a cafe when Asuna brought up the question whether Shivata and Liten were a couple, and what 'going out' entailed in SAO. Argo, who they had invited, appeared and together they discussed how to proceed with the ALS' plan to beat the boss on their own. Argo revealed she was neither an info broker nor a front-runner in the beta, thus she didn't know anything about that guild flag. They discussed whether they should reveal the plan to Lind, but ultimately Kirito suggested to beat the boss on their own. Argo revealed that the boss quests indicated that the golem from the beta was still the same, and they discussed who they could invite to join them on their attempt to beat the floor boss. Kirito left to invite Nezha, and Asuna to invite Agil and his Bro Squad as well as Shivata and Liten.

Part 9
After Kirito successfully recruited Nezha for the boss fight, everyone met in a forest near Mananarena and exchanged greetings. Asuna had brought Agil's Bro Squad, consisting of Agil, Wolfgang, Lowbacca and Naijan, with her, as well as Okotan from the ALS and Hafner from the DKB additionally to Shivata, Liten and Argo. When asked by Liten why Kirito wouldn't join a guild, Kirito replied that Lind and Kibaou set the condition that he and Asuna would need to join the guild's separately. The group discussed possible formations to beat the fifth boss, but even with a party of only 12 players it was not an easy process. Afterwards Argo revealed a key she received from one boss quest, leading to a shortcut by sunken blocks continuing in a pattern straight up the wall of the tower, similar to an unconventional ladder. Argo gave everyone cushions and demonstrated how to use if they fell, which without would lead to a large amount of damage, and possibly death, as the stone wall was 20 metres in height.

Due to this shortcut, the group skipped almost twenty percent of the Labyrinth as they began to tackle it. On a small observation deck, Asuna provided a cake for everyone, that she had purchased in the cafe in Mananarena, the location of which was not known to many people. Kirito thought about everyone's motive joining his boss attempt, and why he was leading them when he had publicly declared to be a beater, acting only for his own personal gain. Kirito came to the conclusion that his antagonism towards Morte and his provocateurs may be the reason. Sensing Kirito's internal struggle, Asuna gripped his hand and told him that it was the thanks for his buff on the third floor, when he had held her hand while she melted down her Wind Fleuret. Kirito made a note to himself to ask Asuna later why she agreed to join the boss fight.

Kirito announced the group formation, with two teams of six players each, one consisting of only tanks and the other only of damage dealers. Kirito went on and explained why this formation, usually considered sub-optimal, was his choice. The boss, according to his beta information, should not have any long range attacks, and they didn't have enough tanks to split evenly for potion rotation. After words of encouragement, the fifth floor boss battle started at 4:15 PM, on December 31, 2022.
