100 free Sword Art Online trivia questions with answers — trivia quiz, new questions added Oct 2026.

This SAO quiz covers all the arcs: Aincrad and its 100 floors, the fairy world of ALO, Gun Gale Online and Death Gun, the Underworld of Alicization, plus the films Ordinal Scale and Aria of a Starless Night. Expect questions on Kirito, Asuna, Sinon, Leafa, Eugeo, the voice cast, the theme songs and the real-world history of the series. Every answer is sourced and explained.

Q 01Who wrote the Sword Art Online light novels?
Reki Kawahara
Reki Kawahara says the one trait he shares with Kirito is that neither is any good at forming parties: he jokes that both of them mostly play online games solo.
Q 02How was Sword Art Online first released, from 2002 to 2008?
As a free web novel
As a free web novel on its author's own site, the story grew to four arcs; he took every chapter offline when a publisher offered to put the series into print.
Q 03Under which imprint are the Sword Art Online light novels published in Japan?
Dengeki Bunko
Dengeki Bunko's editors asked for the series after its author won their annual contest with a different story; he had written SAO for the same contest years earlier but never entered it, as it ran far over the page limit.
Q 04What is missing from Sword Art Online's menu on launch day?
Log-out button
The log-out button's absence is no bug: the game's creator appears to announce that he removed it, that clearing the whole castle is the only way out, and that dying in the game now means dying for real.
Q 05What is the name of the helmet that lets players dive into SAO by stimulating their senses?
NerveGear
NerveGear cuts off the body's own signals and feeds the brain a virtual world, so pulling it off by force, or dying in the game, kills the wearer; the later AmuSphere was sold as its safe replacement.
Q 06Who created the game Sword Art Online in the story?
Akihiko Kayaba
Akihiko Kayaba ends his own life once the game is beaten, scanning his brain at lethal power to leave a copy of his mind on the network, and that copy later comes to Kirito's aid.
Q 07How many players log into SAO on launch day and become trapped?
10,000
10,000 players are caught on day one, and only the 1,000 who had been let into the pre-launch trial, Kirito among them, already know the early floors, which is why he pulls ahead so quickly.
Q 08What is the name of the floating steel castle that serves as SAO's setting?
Aincrad
Aincrad does not stay gone: once the death game is over, the castle is rebuilt inside another game as New Aincrad, and the survivors go back to climb the floors they never reached.
Q 09How many floors of the castle must SAO's trapped players clear to be set free?
100
100 floors was the target, but the game ends early on the 75th, when Kirito unmasks the creator hiding among the players and beats him in a duel.
Q 10What is Kirito's real name?
Kazuto Kirigaya
Kazuto Kirigaya built his player name from his real one, joining the front of his family name to the end of his given name: KIRIgaya kazuTO.
Q 11The insult "beater", hurled at Kirito, is a portmanteau of which two words?
Beta tester and cheater
Beta tester and cheater: the crowd hurls the word at Kirito after the first boss falls, and he accepts it on purpose so that their anger lands on him instead of on every former tester.
Q 12What in-game alias did Sword Art Online's creator use as leader of the Knights of the Blood Oath?
Heathcliff
Heathcliff meant to turn on the players as the final boss at the very top of the castle; Kirito sees through the disguise early and wins everyone's freedom in a duel.
Q 13Which fairy race does Kirito pick for his avatar in the game where he searches for Asuna?
Spriggan
Q 21What is the real name of the sniper Sinon?

Q 22What experimental FullDive machine does Kirito test for the organization RATH?
The Soul Translator
The Soul Translator reads and writes to the user's soul itself, not to nerve signals, and RATH blocks Kirito's memories of each test dive so that nothing about the project leaks out.
Q 23In Sword Art Online's Underworld storyline, what is the name for the quantum light that makes up a person's consciousness?
Fluctlight
Spriggan, the shadow fairies, are his choice, and because the new game runs on a copy of SAO's servers he arrives with all his old skill levels intact.
Q 14In which fairy-themed game does Kirito search for Asuna in the second arc?
Alfheim Online
Alfheim Online lets its players fly as fairies, and it is run by a subsidiary of the company Asuna's own father heads, which is how her captor can hide her inside it.
Q 15What is the avatar name of Suguha, Kirito's cousin and adoptive sister?
Leafa

Q 16What is Yui, the child Kirito and Asuna adopt in SAO?
An artificial intelligence

Q 18What is The Seed, which SAO's creator leaves to Kirito?
A toolkit for building VR worlds

Q 19In which game is Kirito given a long-haired, feminine avatar?
Gun Gale Online
Gun Gale Online is the one game in the series whose winnings can be cashed out for real money, so professionals play it for a living, and it is those top players that the killer picks off.
Q 20Kirito enters which battle-royale tournament in order to hunt a killer?
Bullet of Bullets
Bullet of Bullets finalists shot by the masked Death Gun die in real life too, because an accomplice is waiting in each victim's home with a syringe at the moment the avatar is hit.

Q 24In the Underworld, a village girl is taken away by the Integrity Knights for breaking what?

Q 25Who is Kirito's closest friend in the Underworld, a wood-carver from the village of Rulid?

Q 29Which studio animated the Sword Art Online TV series?
