Sword Art Online Season 1: Aincrad Arc (Series, 14 Episodes, 2012)
The first season of Sword Art Online draws viewers into the VR world of Aincrad, a fantasy realm filled with monsters, magic, and medieval castles.
In the first episode, teenager Kazuto “Kirito” Kirigaya joins 10,000 other players for the launch of the highly anticipated MMORPG Sword Art Online.
But the gamers soon discover that developer Akihiko Kayaba has trapped them inside Sword Art Online. And if they die in the game, they will die in real life too.
Their only means of escape is to progress through all 100 floors of Aincrad and defeat the final boss.
With gripping life-or-death stakes, Kirito bands together with other players like Asuna to take down bosses and slowly climb towards freedom.
Along their perilous journey, bonds of friendship and even romance form. But they also experience the heartbreak of allies falling in battle.
After 14 intense episodes, Kirito finally beats Sword Art Online, freeing himself and Asuna. But a shocking revelation waits in season one’s second arc, “Fairy Dance.”
Sword Art Online Season 1: Fairy Dance Arc (Series, 11 Episodes, 2012)
The “Fairy Dance” arc picks up shortly after the liberating defeat of Sword Art Online.
But while Kirito has returned to the real world along with most of the other players, 300 SAO users remain unconscious, including his love Asuna.
When Kirito visits her hospital room, he learns Asuna and the other victims have been trapped inside another VR game called Alfheim Online. And devious reasons lurk behind their imprisonment.
Determined to rescue Asuna, Kirito dives into the new fantasy world of Alfheim, filled with magical fairies and treacherous dungeons.
But conniving schemes and powerful guardians that await in ALO might thwart his efforts. And what will he find when Kirito finally reconnects in-game with Asuna?
Sword Art Online: Extra Edition (Movie, 2013)
After the dramatic events of season one, the lighthearted movie Sword Art Online: Extra Edition provides some fun downtime.

Extra Edition brings closure to season one while planting more seeds of future stories. It also gives Asuna and the other female characters more satisfying screen time.
Sword Art Online II
The next essential phase of the SAO storyline plays out in Sword Art Online II. The season opens one year after the infamous SAO incident with the Phantom Bullet arc.
A new VR game called Gun Gale Online, featuring gun battles in a desert wasteland, has taken the gaming scene by storm.
But when a mysterious player called Death Gun starts shooting rivals in GGO and causing their real-life deaths soon after, it draws the urgent concern of government authorities.
They recruit Kirito to enter GGO and investigate, believing his experience can uncover whether it’s coincidence or foul play at work.
Teaming up with ace sniper Sinon inside the bullet-ridden VR world, Kirito prepares for his deadliest virtual opponent yet.
After the tense action of Phantom Bullet, Calibur delivers some lighter adventures. This short arc brings Kirito and friends back to Alfheim on a quest to find a legendary weapon.
It serves as an enjoyable break before the emotional gut-punch of Mother’s Rosario.
The arc shifts focus to Asuna befriending a seemingly unbeatable ALO sword fighter named Yuuki.
Their blossoming friendship leads to a medical revelation outside VR that will leave viewers profoundly impacted. Bring tissues.
Sword Art Online the Movie: Ordinal Scale
Following the battering of emotions in season two, the movie Sword Art Online the Movie: Ordinal Scale dials excitement back up to 11.
Set after Mother’s Rosario, the film introduces the new gaming craze of augmented reality (AR).
With a high-tech device and headset called an Augma, Ordinal Scale overlays elaborate monsters and battles onto real-world arenas through dynamic 3D mapping technology.
It quickly becomes the first ARGMMORPG – an AR game fusing magic and technology.
Asuna and other SAO survivors eagerly adopt the innovative Augma system. But when glitches start occurring and SAO nightmares resurface, Kirito suspects foul play.
His investigation into the system leads him to clash with Ordinal Scale’s mysterious creators. The realities of virtual worlds and real life blur once again…
Sword Art Online Season 3: Alicization
The series then progresses to its longest and most complex arc with Sword Art Online Alicization. The story in Underworld begins when Kirito takes a job testing an experimental new FullDive machine for a shady research company.
During a system error, his mind gets trapped in Underworld, an AI-driven realm designed to cultivate artificial human souls, known as Artificial Fluctlights.
Robbed of his real-world memories, Kirito struggles to make sense of this strange new land. He befriends young residents Eugeo and Alice while piecing together his foggy identity.
But this artificial world proves nearly as dangerous as those he previously braved when corrupt forces exploit Underworld for twisted experiments. A mind-bending sci-fi saga split over two seasons, Alicization escalates SAO to bold new frontiers of virtual reality.
The War Rages On in Alicization – War of Underworld
In the suspenseful conclusion, Alicization – War of Underworld Parts 1 & 2, the experiments conducted in secret within Underworld’s virtual realm trigger calamity in Ocean Turtle, the offshore base housing the system in the real world.

What began as tests of artificial souls soon erupts into a full-fledged war for the fate of humanity. Lives in and out of VR hang in the balance.

With the ruthless Dark Territory army marching to destroy Human Empire resistance, the their only hope rests on buying time for Kirito to regain his strength.
