Argo (アルゴ) is one of the 10,000 players who were trapped in «Sword Art Online» and a beta tester who sold information between players. Kirito often looked to her for information. She also served as a middle-man of player dealings.

Sword Art Online
Argo is a nimble-looking player who has brown eyes and curly auburn hair. She wears full-body cloth and leather armour, a hooded cloak and also has whiskers on her face, which were originally a mark from a quest, but now a makeup of her choice. Her weapon of choice are claws, which she hangs at her left waist. She also uses Throwing Picks, which she hangs on her right waist.

ALfheim Online (Lost Song)
In the non-canon game adaptation, Sword Art Online: Lost Song, Argo plays ALfheim Online as a Cait Sith. Her avatar has blonde hair and yellow-green eyes, a new outfit similar to that worn by her SAO avatar, and a pair of wrist-mounted blades as weapons.

Personality
Argo is a completely business-focused person, with people saying that she would sell her own stats or grandmother for Cor. Despite that, she has been known to honor her debts, as was the case with Kirito, saving her from the ninja clan. She is so focused on completing her field guides that it sometimes gets her into trouble.

Argo is willing to sell any information except the names of SAO beta testers.

Background
Argo's whiskers were originally a mark written on her face when she tried to complete the quest that awards the «Martial Arts» Extra Skill. Unable to complete the quest, the mark remained on her face throughout the entire «SAO Closed Beta». She reapplied a similar makeup on the official server service.

Aria of a Starless Night
Argo was first introduced as the beta tester who served as a middleman between Kirito and a prospect buyer of his «Anneal Blade +6». She was later revealed to have assisted players by creating the guide book, «Strategy Guide by Area», a pamphlet freely distributed in NPC shops. Inside were hunting locations and other useful information pertaining to staying alive in the death game.

After the 1st Floor boss battle, as Kirito declared himself a Beater and took the hate towards beta testers, which was re-sparked by Argo's information guide on the boss having been incorrect due to changes before the official release, upon himself, Argo promised that she would disclose any information with him for free. He then asked for the reason behind her whiskers.

Reason for the Whiskers
When Kirito opened the gate to the 2nd Floor, he noticed Argo running away from two players. He ran after them, using his Tracking Mod to stay close behind. After catching up, he realized that the two players were dressed in a ninja-like outfit. They were asking Argo about a quest on the 2nd Floor that she refused to sell.

At this time, Kirito revealed himself and jumped in-between Argo and the two players. The two eventually ran away after they realized that a large cow mob was behind them which chased after them for some distance. Argo thanked Kirito for helping her, and said that rather than telling Kirito about why she wears the make-up, she will show him, which will also show Kirito the quest that the two "ninja" wished to have. After Kirito promised that he would not hold a grudge against her no matter what happens, Argo showed him the quest NPC and he accepted the quest given, which was to break a rock that was near unbreakable. However, as he had already accepted the quest, the NPC was prompted to mark his face with whisker-like markings until he could successfully split the rock in half and thus complete his quest. He realized that the reason why Argo kept the markings, even after the Beta test period, was because it had become a part of her image. He eventually broke the rock after three days and three nights.

Red-Nosed Reindeer
About the time of Christmas Eve, 2023; Argo provided information on the possible location of Nicholas The Renegade, the Christmas event boss, to Kirito. Afterwards, she sold the information about Kirito purchasing the information about the boss to Klein, while, later, Kirito also bought information about Klein buying information about his recently purchased information.

The Day Before
While investigating newly appearing quests of a mysterious nature, Argo picked up a quest on the 22nd Floor. A key character in the quest was a dog, which Argo has problems with, so she out-ran the dog, and proceeded to a log house. The house is then pulled up by a tornado, and was suspended near the top of floor. She was trapped there for two days, before Kirito and Asuna came by looking for the house that she was trapped in. Asuna was the first to become aware of the house floating above the ground, and Kirito realized that someone was waving their hand out the house. They were unable to determine if the person was a player, or NPC, until Argo tossed out a used healing potion, which indicated that the person trapped above was a player.

Deciding to help whoever was trapped above, Kirito and Asuna attempted to reach the point that was directly beneath the house. They came upon a tall tree. A dog then appeared, and Asuna picked it up, causing the two to be swept up by a tornado, and end up inside the house with Argo. Argo complained that they were not supposed to come up there with her, but explained her situation, and the two were pulled into a quest that she was doing. Kirito realized that she out-ran the dog, as she was bad with dogs, but that caused the quest to become stuck. Argo realized that the house they were in was moving, and eventually came upon an area on the 22nd Floor that was unreachable by foot. After meeting three NPCs: a Tin-man, a lion, and a scarecrow, Argo and Asuna realized that this quest was based on the «Wizard of Oz».

Deciding to skip the sub-quests, Argo and Asuna decided to go straight to the Witch's Castle, which they managed to pass through easily, due to their much higher levels than the quest was made for. After defeating the Witch and returning from the quest, Argo promised not to tell anyone about Kirito and Asuna's marriage, which she figured out on her own.

November, 2024
It is presumed that Argo was among the remaining 6,147 players logged out of the death game after Kirito killed Heathcliff, prematurely clearing the game.
