His greatest goal in life is to go to the Central Cathedral and rescueAlice Zuberg。
Childhood friend of Alice and Kirito, all three were born in the same yearThey also promised to wait together until their Life reached zero. At the age of 11, the three of them crossed the cave of the northern End Mountains, discovering the Blue Rose Sword and the Dark Territory on the other side of the mountains. Because Alice touched the Dark Territory, she was taken away by an Integrity Knight. When Kirito swung his axe at the Integrity Knight, Eugeo was stopped by the Code 871 seal and could not move an inch. After "Kirito's" existence disappeared, he continued his Calling of cutting down the giant tree, but his heart suffered from his own helplessness until six years later, when a boy named Kirito appeared before Eugeo, who was working as a Hewer.
He defeated a goblin squad in the cave, rescued Alice's younger sister, and increased his authority enough to lift the Blue Rose Sword. He cut down the tree that refused to be felled and was supposed to fall hundreds of years later. He became a swordsman alongside Kirito, moving forward with the goal of becoming an Integrity Knight, entering the Central Cathedral, and saving Alice.
In the Swordcraft Academy, he became a valet just like Kirito, and after their seniors graduated, he likewise had his own junior valetTiese Shtolienen. When Tiese and Kirito's valet Ronye were being punished by a wicked noble using the rules of the law and were about to be defiled, and Eugeo was unable to stop it, he broke through the Code 871 seal in his right eye and swung his sword at the opponent even as his right eye shattered. Together with Kirito, who also cut off the opponent's arm, he was arrested by Integrity Knight Alice Synthesis Thirty.
The two escaped from the dungeon, and withCardinal's limited help, they broke through the Integrity Knights' lines of defense one after another. On the 81st floor, the impact of the weapon release from Integrity Knight Alice and Kirito broke the wall, and the two were blown outside. Eugeo was forced to proceed alone and encountered the strongest Integrity Knight, Bercouli Hylanz. Eugeo decided to take Bercouli down with him, and the weakened Eugeo was brought before the Administrator by the Elder. He was manipulated by the Administrator's words, which exploited his weakness of lacking love,and after being subjected to indescribable temptation,he gave up resistance and became Integrity Knight Eugeo Synthesis Thirty-two, freezing Alice and Kirito, who had also broken through the Code 871 seal. Although he regained his self-awareness, he could no longer face the companions he had turned his blade against.
He decided to assassinate the Administrator alone but failed; he was rescued by the other two who caught up, and together they fought the final battle against the Administrator. He requested the dying Cardinal to turn him into a sword, and together with Alice's sealed memories (Fluctlight), he transformed into a sword and destroyed the giant Sword Golem, which was condensed from the lives of 300 people and the love stripped from 30 Integrity Knights. He was cut into two along with the swordEuge][o. He handed the blood-stained Red Rose Sword to Kirito, recreating the image of the Dual Blades Black Swordsman Kirito. Eugeo stopped Kirito from saving him because Eugeo fought for his childhood friend, AliceZuberg(whose Fluctlight had been stored independently), while Kirito would never give up on AliceSynthesis Thirty(who is also a person with a Fluctlight/soul). Ultimately, Eugeo left this world together with Alice Zuberg (the sealed Fluctlight of young Alice), leaving the future to Kirito and Alice Synthesis Thirty.
The broken Blue Rose Sword was held in the arms of Kirito, who had lost his sense of self. After Kirito woke up, he repaired it using Incarnation. In the final battle against Gabriel Miller, Eugeo's Fluctlight fragment blocked Miller, buying Kirito the opportunity for a decisive victory.
After Kirito re-logged into the Underworld, he appeared on the Blue Rose Sword, waving to the pilot of the mechanical dragonBlue Rose 73, who was a descendant of Tiese.
