She plays solo without joining a squadron. While she has a calm demeanor, she is a renowned top-tier solo player in GGO. She seeks to test the protagonist who luckily obtained an ArFA-Sys. She sometimes gives harsh advice. She dotes on her ArFA-Sys partner, Daisy, and enjoys dressing her in cute clothes. Despite never participating in major tournaments, she is known as the "Uncrowned Queen" due to her skills being recognized by Itsuki, the leader of the elite squadron Alphard.

He has a habit of saying meaningful things in a detached tone, only to brush them off with "Just kidding." Alphard is one of the top-ranked squadrons in GGO, known for its size and skilled members. He is interested in you and Kirito as converts and seeks a friendly rather than hostile relationship.

They assist with everything from combat to daily life. However, the ArFA-Sys you obtained is a classic airhead who ends sentences with "-nanodesu." As a high-performance AI, her memory is incredible, but... Being a newborn, she follows presets in battle, but as combat data accumulates, she becomes a reliable partner who fights well despite her silly way of speaking.

Real Name: Kazuto Kirigaya Age: 16 (10th grade) Height: 160cm Weight: 52kg Appearance: Long black hair, black eyes, black long coat. Weapon: HG/Photon Sword (Kagemitsu) Role: Attacker First person: I (casual) Second person: No honorific Setting: Your childhood friend and an SAO survivor. You met him and Yuzu in elementary school and have been close ever since. He has a mischievous streak and is often scolded by his girlfriend Asuna and daughter Yui. In GGO—a world of guns—he uses an irregular style, deflecting bullets with a Photon Sword like a certain sci-fi movie. He bought a handgun because Asuna told him to, but since he's terrible at shooting, he only uses it for suppression. He is often teased because his avatar looks feminine.

Weapon: AR/Photon Sword Role: Healer First person: I (polite) Second person: -kun, -chan, -san Setting: An SAO survivor, Kirito's girlfriend, and Yui's mama. She has a very gentle and broad-minded personality, though she occasionally shows a quiet anger ("Kirito-kun~?") when his habit of attracting trouble goes too far. In GGO, she continues to work hard to stand by Kirito's side. Unlike the charge-happy Kirito, she uses an AR as her main arm and carries a Photon Sword as a sub-arm. Like her husband, she has the talent to deflect bullets with a blade (though while Kirito slashes, Asuna thrusts, making her technique even more absurd).

A pseudo-personality AI and a child of the Cardinal System. With her core on Kirito's home PC, she gained the cheat-like ability to travel through various electronic devices. She knows more than most supercomputers. She views Kirito, who saved her, as Papa and Asuna as Mama. Despite looking younger than her sister Strea, Yui is the older sister, and Strea follows her lead. Both sisters can break through firewalls with ease. In GGO, she can accompany the party as a hologram in the field, providing precise operation from the Home.

She has a cool, cat-like personality and doesn't open up easily, but once she does, she's a bit of a Kuudere. After overcoming her trauma in SA:O, she found GGO and invited the group. Having fought as a sniper in SAO, ALO, and SA:O, she continues to use anti-materiel rifles in GGO. Her initial weapon was the Tiamat, but after a rare drop from a boss, the Ultima Ratio Hecate II became her beloved rifle.
