Eugeo

Eugeo (ユージオ) is a protagonist in «Project Alicization».

Background
Eugeo is a wood cutter of Rulid Village and Kirito's childhood best friend in the beginning of the Alicization arc, during Kirito's first dive, when his memories of the real world were suppressed. He, along with Kirito, were given the Sacred Task of cutting down the «Gigas Cedar». After their friend Alice was taken away by Integrity Knight Deusolbert Synthesis Seven, Kirito seems to have disappeared from the memories of the people of Rulid, including Eugeo, who is later shown to somehow still have faint memories of a person who tried to save Alice from the Integrity Knight, but doesn't remember who the person was. However, upon Kirito's return to Underworld, in which he has no memory of his first dive, Eugeo is the first person Kirito (as Kazuto), encountered upon awakening.

Alicization Beginning
Eugeo has been Kirito's friend since childhood, and has just received the Sacred Task of cutting the Gigas Cedar tree with Kirito. While having meal with Alice and Kirito they decide to travel to a cave in the Mountain Range at the Edge. They find ice in the cave, along with the bones of a dragon and the Sword of Blue Rose. On their way out, they confuse the tunnels and enter one conducting to the Dark World and see the battle between a Black Knight and an Integrity Knight. The next day along with Kirito he tries to save Alice from the Integrity Knight but they are unutilized by the villagers.

He is the first person Kirito encounters when he returns to Underworld and helps him find where to stay on the village. The next day, he shows Kirito the Sword of Blue Rose he brought from the cave in the Mountain Range, but they are unable to use it. He helps Kirito look for Selka when she escapes and fights the Goblins in the cave, but is gravely injured. Kirito and Selka save his life and after two days he returns to his task of cutting the Gigas Cedar. He finds it easier to wield the Dragon Bone Axe, so Kirito prompt him to use the Sword of Blue Rose,with Kirito's assistance he manages to master the use of the Horizontal Sword Skill and cut the Gigas Cedar in the process in just five days. On the festival organized to celebrate his feat he reveals that he wants to be a swordsman and leave the village, but is challenged by Jink to a duel to decide who will leave the village. With Kirito's advice he easily defeats Jink, and with Kirito they depart to Zakkaria.

Alicization Running
Since leaving the village, Eugeo and Kirito have been working as stable-boys in the «Wilde Farm» on the outskirts of Zakkaria for about 5 months, training and waiting for the tournament. On the 28th of August, the day of the tournament, Kirito and him are about to enter the West gate of the town a when a horse goes wild and charges them but fortunately they are able to calm it down and discover the cause of its distress to be a «Large Marsh Horsefly». Kirito gives his suspicions on why one is so far from the nearest swamp and warns him to be wary of future incidents.

As the pair stop to get some food, Eugeo gets a bit nervous from seeing more people than he is used to in Rulid Village but Kirito tries to get him to loosen up. After signing up for the tournament, both of them enter the tournament restroom and after scouting quickly they are relieved that none of the participants are female. While they prepare Kirito comes up to him and warns him of one of the participants whose personality is similar to Jink's.

Both he and Kirito are able to be in different blocks during the tournament and somehow are able to pass the preliminaries, win the tournament in their respective blocks, and both become guards. By next spring, each of them receive letters of recommendations to attend the Royal Swordsmanship Academy. After they enter he becomes the valet of the 3rd best swordsman in the academy, Golgosso Valto.

One and a half year passed since the tournament. After practice he talks with Kirito during dinner and later helps him with the plants he is growing, where he asks about what will Kirito do after recovering his memory. After Kirito asks for his sword he reminds him that the next day, March 6th, something important was going to happen.

The next day was a rest day, so they went to the city and visited Satore's shop in the 7th district of North Centoria, Satore gives Kirito the sword he crafted from the branch of the Gigas Cedar. After Kirito takes the sword they return to the academy.

Later he hears some commotion, and discovers that Kirito was going to face the head-elite-swordsman of the Academy in a duel. After the duel, he is invited along with Golgosso to Solterina's room to celebrate Kirito's duel.

A few months later, he's ranked as a elite-swordman in the Academy, and is about to dissmiss Teiza, his valet, when he sees Ronie valet waiting for Kirito to be dissmissed, and offers her to change from elite-swordman, as he sees that Kirito isn't a good example. She declines and in that moment Kirito enters from the window with a bag of honey pies for them and dissmiss their valets by telling them to share them with their roommates.

He gets a duel with Humbert, while Raios is the referee, he manages to make Humbert stumble by connecting two skills and repelling his attack, Raios stops the duel before Eugeo lands the final strike.

Days later he has a picnic with Kirito, Ronie and Teiza, where the later two explain the situation that thier friend, Frenica, was having as Humbert's valet, since he was venting his arge from drawing with Eugeo on her.
