If you've been searching for details on a character named "Yuno" in Sword Art Online: Alicization, you've likely hit a bit of a snag. It's a common point of confusion, but we need to clarify upfront: there is no character named Yuno in Sword Art Online: Alicization.
The name "Yuno" often brings to mind other popular anime characters, perhaps Yuno Gasai from Mirai Nikki or Yuno Grinberryall from Black Clover. However, within the intricate world of Rath's Project Alicization and the virtual realm of Underworld, this character doesn't exist.
Instead, Sword Art Online: Alicization introduces a rich cast of characters, both new and familiar, whose ages and experiences are deeply intertwined with the unique temporal mechanics of the Underworld. If you're curious about the ages of the actual protagonists and antagonists, you've come to the right place. We'll dive into the ages of the key players and explain how time itself operates differently in this fascinating arc. For a more comprehensive understanding, consider a .
Untangling the Timeline: Key Character Ages in Alicization
Sword Art Online: Alicization picks up after the Ordinal Scale film, placing Kirito, Asuna, and their friends chronologically in the mid-2020s. However, the unique nature of the Underworld simulation drastically alters how "age" is perceived and experienced by many characters.
Kirito (Kazuto Kirigaya): The Star King's Journey
When Kirito (Kazuto Kirigaya) begins his "work" for Rath, testing the Soul Translator (STL) and subsequently gets drawn into Underworld, he is a high school student, just turning 18 years old. Born on October 7, 2008, the events of Alicization primarily unfold from October 2026 onwards.
His time in Underworld, however, is a different story. Initially, he enters with no memory of his real life, living for several years alongside Eugeo and Alice. After the climactic battle with the Administrator and the subsequent real-world attack on the Ocean Turtle, Kirito is left in a catatonic state. Later, after the War of Underworld, Kirito and Asuna choose to remain in the accelerated Underworld, experiencing 200 subjective years before returning to the real world with their memories of that time erased. To trace , delve into his dedicated pillar.
Alice Zuberg: From Child to Integrity Knight to AI
Alice Zuberg's age is one of the most complex in Alicization. She is initially introduced as a young girl, a childhood friend to Kirito and Eugeo. Within the Underworld's timeline, she is approximately 11 years old when she is taken away by an Integrity Knight for violating the Taboo Index.
However, due to the unique way the Underworld simulation accelerates time, by the time Kirito re-enters and begins his quest, roughly eight subjective years have passed for the residents of Underworld since Alice's abduction. This means the Integrity Knight Alice Kirito encounters appears to be around 19 years old. Her physical age remains consistent as a young adult throughout the arc, but her 'experienced' age, especially after being the target of Project Alicization, makes her a truly unique entity.

Eugeo: Kirito's First Friend in Underworld
Eugeo, Kirito's devoted companion and close friend in Underworld, shares a similar timeline to Alice. When Kirito first awakens in Underworld, Eugeo appears to be roughly 19 years old, having lived in Rulid Village for years following Alice's disappearance. His journey with Kirito defines much of the early Alicization arc. Explore .
Asuna Yuuki: The Goddess Stacia
Asuna Yuuki, Kirito's partner in the real world, is roughly the same age as Kirito, being born on September 30. She would be around 18-19 years old during the main events of Alicization in the real world.
When Asuna dives into Underworld as the Goddess Stacia during the War of Underworld, she experiences the accelerated time alongside Kirito, especially during their 200-year stay. While her real-world age remains unchanged, her subjective experience within Underworld drastically increases her perceived 'age' in terms of accumulated time.
The Temporal Fabric of Underworld: A Key Factor in Character Ages
One of the most defining features of Sword Art Online: Alicization is the time acceleration within the Underworld. This is pivotal to understanding the perceived ages of characters born within the simulation. Rath, the clandestine organization behind Underworld, can manipulate the flow of time within the virtual world, making days, months, or even years pass in mere moments in the real world. If you're curious to , our dedicated guide explains it all. This technology is at the heart of .
This acceleration means that while Kirito might only be away from the real world for a few months, characters like Alice and Eugeo, who were born and lived their entire lives within Underworld, subjectively experience many years. The later 200-year leap for Kirito and Asuna is the most dramatic example of this phenomenon.
Other Significant Characters and Their Ages
Beyond the core trio, Alicization features a host of memorable figures, whose ages contribute to the depth of the narrative:
- Quinella (The Administrator): The primary antagonist of the first half of Alicization, Quinella has existed for hundreds of years within Underworld's accelerated timeline. She appears as a young, elegant woman but is ancient, having perfected her control over the Fluctlight generation and memory manipulation. She is one of .
- Bercouli Synthesis One: The first Integrity Knight and a formidable warrior, Bercouli is also hundreds of years old, a seasoned veteran of Underworld's history. He, like other , possesses vast experience gained over centuries.
- Suguha Kirigaya (Leafa) and Shino Asada (Sinon): Kirito's sister and fellow VRMMO player, respectively, are similar in age to Kirito and Asuna, being high school students in the real world. They both dive into Underworld during the War of Underworld to assist their friends.
Knowing helps to contextualize everyone's age relative to previous arcs.
