ユージオ,

Eugeo is a protagonist in Alicization Beginning. Eugeo is a wood cutter of Rulid Village and Kirito's best friend in the beginning. Kirito was then unheard of when their friend Alice was taken away. However, upon Kirito's return to Underworld, in which he has no memory, Eugeo is the first person Kirito (as Kazuto), encountered upon awakening. He was given the Sacred Task of cutting down Gigas Cedar. (Source: SAO Wiki)
