Deep within the 50th floor of the death game *Sword Art Online* (SAO), the air is thick with the damp, musty smell and the clanging of metal. Each floor of Aincrad, this floating castle, is a relentless testing ground where players fight tooth and nail for survival and victory. Kirito, player ID "Kirito," wields dual swords, nimbly dodging attacks from a horde of goblin monsters. His black hair flutters slightly in the virtual wind, his sharp eyes fixed intently on the battlefield. As a solitary genius player, he's long been accustomed to facing danger alone, but everything changed after meeting Asuna.
