Ages of the main characters in the anime Sword Art Online, from Kirito to Silica.
There is a new game realm in Sword Art Online, one in which the characters are able to interact with the virtual world and even live there. It’s a place where anyone may go lost, and that’s exactly what happened to the 10,000 characters who lived there.
It can be difficult to keep track of the ages of the characters in this series, as they appear at various points in their lives. There are certain characters in this story who aren’t quite human. If one considers biology or time when determining a person’s age, then the number can change. However, Reki Kawahara was able to provide fans with the ages of some of the characters in the show.
1. Kazuto Kirigaya / Kirito (14 – 17)
“Kirito,” or Narusaka Kazuto, is the main character of the Sword Art Online series.
An orphaned child, Kazuto was taken in by his aunt as an infant and grew up to become a well-known hacker and an accomplished gamer.
The Black Swordsman to the Star King were only a few of his many Sword Art Online monikers. For example, Kazuto is 14 years old at the beginning of the Aincrad Arc; at the end, he’s 16.
2. Asuna Yuuki / Asuna (15 – 18)
Asuna Yuuki, also known as “Asuna,” “Stacia,” and other monikers, is the star of the show’s main series. A former RECT Inc. CEO’s daughter, she was one of the Sword Art Online participants who became stuck in the virtual world.
At various points throughout the series, Asuna’s age changes. When she begins the Aincrad Arc, she is 15. She’s 17 by the time it’s over. She is 18 as of the Phantom Butler Arc.
3. Suguha Kirigaya / Leafa (15 – 17)
Suguha Kirigaya Suguha, also known as “Terraria” and “Leafa,” is a recurring character in the series, with important roles in several arcs and spin-offs.
As a way to pacify their grandfather after Kazuto decided to abandon kendo, she became a kendo practitioner. When Kazuto got sucked into the virtual world of Sword Art Online, she was drawn in.
During the Fairy Dance Arc, she is 15-years-old, 16-years-old, and 17-years-old, respectively.
4. Shino Asada / Sinon (16 – 17)
During the Phantom Bullet Arc and the Alicization Arc, Asada Shino, also known as “Sinon” and “Solus,” assumes a key part in the storyline.
In the game, she’s a great archer who uses the virtual environment to overcome her traumas. During the Alicization and Phantom Bullet arcs, she is 16 years old. She was 17 years old at the time of the Unital Ring Arc.
5. Yuuki Konno / Yuuki (15)
Yuuki, a character commonly referred to as Konno Yuuki, plays a significant role in the show’s side tales. She is a member of the “Sleeping Knights” guild, one of its founders and commanders.
While near death, she banded together with other gamers in a similar situation to use the game as a tranquilizer. While still a teen at the time of her death (in 2026), she had been born in 2010.
6. Eugeo (11 – 19)
For much of the Alicization Arc’s first act, Eugeo is a major player. With Kirito at his side, he was given the mission of defeating a gigantic tree known as the Gigas Cedar. Alice Zuberg’s kidnapping sparked a desire in him to save her, which resulted in him taking up the Blue Rose Sword, becoming a knight, and proving his ability to use it.
Throughout the show, we see Eugeo in a variety of stages of development. In the prologue, he is 11 years old, and in the first chapter of the arc, he is 17. While Quinella is still alive during the time of most of his appearances, he is still only 19 years old.
7. Alice Zuberg (11 – 17)
The Alicization Arc sees Alice Zuberg take center stage.
Childhood friend of Eugeo and Kirito’s, she was the daughter of a village chief and compelled to join an Integrity Knight, where she was deprived of her memories and known as “Alice Synthesis Thirty.”
Like Eugeo, she was 11 at the beginning of the arc, 17 at the beginning of the first chapter, and 19 at the end of the chapter.
8. Ryotaro Tsuboi / Klein (22 – 25)
Ryotaro Tsuboi is an important figure in the Aincrad arc, going by the alias Klein. One of tens of thousands of people stuck in a virtual world. Both as a guild leader and as a Salamander, he has earned this reputation.
By the beginning of the Aincrad Arc, one of the older notable characters was 22 years old, and at the end of it, he was 24 years old. His age was 25 at the time of the Phantom Bullet Arc.
9. Andrew Gilbert Mills / Agil (27 – 30)
Recurring character Agil, Andrew Gilbert Mills (commonly known as Agil), takes a key part in the Aincrad Arc. He was a trader and an ax-wielder in the virtual reality world of Dicey Cafe, where he and his wife finally managed the business together. Also, he appears to be a Gnome.
When Aincrad began, he was 27; when Fairy Dance began, he was 29, and when Phantom Bullet began he was 30, making him one of the oldest recurring characters in the series. However, his exact year of birth is a mystery; it could have occurred in 1994 or 1995.
10. Keiko Ayano / Silica (14 – 15)
An important character in the Aincrad arc and some of the series spin-offs, Ayano Keiko (commonly known as Silica) has a constant presence throughout the series. She was a Beast Tamer and a Cait Sith in the virtual reality world where she was trapped with the other 10,000 players.
While she was 12 at the beginning of the Aincrad arc, she was 14 at its conclusion and 15 during the Fairy Bullet arc.
