Raios Antinous was a minor antagonist in Sword Art Online : Alicization. He was a swordsman at the Sword Mastery Academy and the eldest son a third class nobile family.
Personality
Due to high status as a noble, Raios was extremely conceited and arrogant , always looking down on people of low status. Because of this, he and Humbert spent the entire time tormenting Kirito and Eugeo, during their time in the academy. Raios was a cruel man, as his used his noble status and the taboo index to his advantage such as destroying Kirito's flowers, and attempting to rape Kirito's and Eugeo's valets, and deeming Eugeo a criminal after the latter cuts Humbert's arm, since the taboo index no longer protected him and attempting to kill him.
Despite his cruelty, Raios didn't have the will to break the taboo index. After both of his arms were cut by Kirito, he asked Humbert to use the ropes he was using to tie his wounds, however since it was the taboo index, Raios struggled between saving his own life and obeying the taboo index; leading to the self-destruction of his Fluctlight.
