Sword Art Online: Alicization is set to air over four seasons starting in the fall of 2018! It is an anime that depicts a grand fantasy that unfolds in the new virtual world, Underworld, that the main character, Kirito, visits. Today, we will introduce the main characters of the virtual world, Underworld.

Kirito (Kirito Kirigaya)

A boy who grew up with his childhood friends Eugeo and Alice in the Village of Rulid, located in the forest of the Northern Empire of Norangarth. One day, while the three were living peacefully together, Alice was taken away by the Integrity Knights for violating the Taboo Index, a law that must never be violated in Kirito's country. In response, Kirito and Eugeo leave the village and go on an adventure to save Alice.

Kirito's memories.

Kirito's memories of the village of Rulid are memories that shouldn't actually exist. The Underworld where Kirito lives is a virtual world, and the real Kirito, that is, Kirigaya Kazuto, grew up in the real world.

Eugeo

A boy with flaxen hair and green eyes, he often plays the role of Kirito's straight man. He is a childhood friend of Kirito and Alice, but has lost his memory when Kirito first meets him. Eugeo reunites with Kirito, and together they leave the village to save Alice and become Integrity Knights!

Eugeo's Strength

After Alice was taken away, Eugeo brought back a sacred artifact called the Blue Rose Sword and kept it. After he began attending the Sword Training Academy with Kirito, he developed a talent for swordsmanship that even surprised Kirito. In the SAO series, only Yuuki has surprised Kirito, so it's safe to say that Eugeo's strength is considerable!

Alice Zuberg

A childhood friend of Kirito and Eugeo, she is the heroine of the Alicization arc. She was taken to the Cathedral by the Integrity Knights when she was young for violating the Taboo Index. The next time Alice appeared before Kirito and his friends was as an Integrity Knight, Alice Synthesis Thirty, and came to arrest Kirito and his friends for violating the Taboo Index. However, after becoming an Integrity Knight, Alice had lost her memories of the time she spent with Kirito and his friends in Rulid Village, and was like a completely different person.

The first Integrity Knight, and the strongest of the Integrity Knights! Apparently he's actually over 200 years old... He possesses a sacred artifact called the Time Piercing Sword, which has the ability to cut into the future (wherever the sword is used to cut, a slash remains, and touching that spot will result in an attack). Bercouli's true identity is the first captain of the guard of the village of Rulid, Eugeo's hometown.

Fanatio Synthesis Two

The second Integrity Knight, her sacred weapon is the Heaven-piercing Sword. She always wears a helmet to hide the fact that she is a woman, but she is actually a very beautiful knight. Even though she later became an Integrity Knight, she was jealous of Alice, who was stronger and more beautiful than her and fought without hiding her true identity. However, after crossing swords with Kirito, she stopped hiding the fact that she was a woman and married Bercouli, the man she had always loved.

So far, we have introduced the characters of Underworld. What did you think? Like Kirito, there are also some surprising characters who have dived from the real world, but it's interesting that the people who are thought to be residents of the Underworld also have their own personalities! This is a very brief introduction, so please watch the anime and get to know the characters better.
