Kirito and Asuna may exist Sword Art Online's key duo, but they're separated for the vast majority of theAlicizationarc. With Kirito in the new VR realm Underworld and Asuna trying to track him downward in the real earth, the couple had their own separate adventures. Simply due to a climactic twist, thepartners got plenty of time to catch upwards – 200 years, in fact.

Near the end of Sword Art Online : State of war of Underworld, Kirito and Asuna chose to stay in Underworld to help ensure Alice's escape to the real world. That conclusion subjected them to 200 years spent in the VR realm equally they were defenseless in Underworld's reboot, during which the Fluctlight'due south technology profoundly accelerated fourth dimension. When Kirito and Asuna finally return, they determine to erase their memories of that time. Let'southward explore why they make this choice and what happened during those two centuries.

Why Asuna Decides to Bring together Kirito For 200 Years

To explain the time skip more than fully, Fluctlight acceleration makes time pass over 1000x faster in Underworld than the real world. Trapped in Underworld for multiple years during the Alicization arc, Kirito was isolated from everyone he knew. That's why it was especially heartbreaking to see him accept a sentence of some other 200 years alone in Underworld during the finale.

In an human activity of truthful love and devotion, Asuna of a sudden appears before Kirito, willing to stay behind and experience the centuries together. She assures him that side by side, they could fifty-fifty accept on a g years together. Every bit they reunite, they also promise not to forget Alice or their many friends on the outside, simply it's unknown how thoroughly they're able to retain such memories. Kirito does address Alice when he wakes, informing her that her sister Selka has entered Deep Freeze to look for Alice.

What Happened During Their Underworld Lifetime

The 200 years Kirito and Asuna spent in Underworld is glossed over, with Sword Art Online showing them waking up in the real globe presently subsequently. A mere slideshow depicting post-war negotiations and parades gives fans a hint almost what happened, but those events are otherwise largely veiled, hopefully to be explored in a later affiliate. However, there is another aspect of their opaque experience conveyed through dialogue: Kirito and Asuna became royalty.

This is offset revealed when Kirito refers to Asuna equally "her highness" when they wake in the real earth. When Rath programmer Takeru Higa makes a re-create of the 200-yr-old Kirito Fluctlight, he questions him further about their experience. Kirito confirms Asuna was Queen and that they discussed the necessity of a retentivity-wipe and the possibility of their Underworld experiences existence copied. Above all, 200-year-old Kirito vows to fight for Underworld's rights then the real earth volition continue it alive.

Kirito and Asuna were known as Star Rex and Star Queen of Underworld, ruling the state for their 200 years spent there. The details of their reign are unclear, but they did proclaim they intended to assistance out the "new world" that Underworld became after the war. Their devotion to Underworld and knowledge from the real world probable made them passionate leaders, but could their political interest truly withstand 200 years?

Fourth dimension Takes Its Price on Kirito & Asuna

Rath hands erased 200 years' worth of Underworld memories per their request, only why was it necessary? While the mystery is meant to leave the audience wondering, there's plenty of sound conjecture to explicate why Kirito and Asuna wanted to leave their Underworld memories backside.

Upon reawakening in the real world, Kirito says in a jaded voice that he and "her highness" are "done in that location" and that they want their memories wiped. This Kirito sounds drastically different than the one from before, with the weight of two lifetimes aging his tone and manner of speech communication. From this alone, information technology'south clear that living through 200 years significantly tuckered them psychologically and emotionally.

The lifestyle of a ruler isn't exactly relaxing either – information technology's likely Kirito and Asuna went through many hard times as King and Queen with new challenges arising in Underworld over the course of two centuries. Information technology'due south entirely understandable that one might want to forget such testing times.

Moreover, going dorsum to their normal life with 200 years of memories riding on the dorsum of their minds seems nearly incommunicable. If they kept their Underworld memories, how could Kirito and Asuna possibly remember all their adventures with their many friends throughout Sword Art Online? While the ii seem rather high-strung up about sacrificing the most uplifting moments, they notice comfort knowing that "deep downward inside the memories are e'er there."

Human being Minds Have Express Retentivity Storage

Even if Kirito and Asuna had desired to hold on to their memories from their stay in Underworld, information technology's possible they simply couldn't. A popular rationale for their retentiveness erasure is that after 2 centuries, they'd reached retentiveness storage capacity. In Sword Fine art Online, there's a limit to the information storage and processing of a man mind.

This concept is starting time shown in Sword Fine art Online: Alicization when Quinella, too known every bit Administrator, approached 150 years old. From losing consciousness to forgetting Sacred Art commands, the years of congenital-upwardly memories actually started to inhibit her ability to procedure her existence. Quinella found a way around it by removing quondam memories and backing them up via Cardinal, but her human retentivity limit remained. This capacity may actually reverberate that of someone from the real world besides.

After 200 years, Kirito and Asuna have conspicuously filled their data storage, significant they'd have to start choosing which memories to erase or face up certain functional drawbacks. Thus, their conclusion to scrap those memories and start fresh seems similar a practical and necessary form of personal maintenance. Luckily, Takeru Higa's copy of Kirito'due south Fluctlight seems to take retained all these memories and stored them separately. Fans curious about what really happened may notwithstanding get a adventure to dive into the many years Kirito and Asuna spent in Underworld in later on Sword Fine art Online chapters.
