Summoned without warning into a towering 100-floor world, nineteen-year-old Jett finds himself caught between survival and destiny alongside 1,999 others from Earth. As most players treat the tutorial as a waiting room, Jett trains relentlessly, earning the attention of a legendary swordsman who bestows upon him a hidden skill unlike any other. Alongside Lyra, his bold lifelong friend, and Emily, a reserved former flame, Jett forms a tenuous trio bound by trust, tension, and shared resolve. Each floor holds deadly threats, evolving systems, and a main mission culminating in a boss that must be defeated to ascend. But climbing the Tower isn’t just about returning home—it’s about growth, sacrifice, and uncovering truths buried in shadow. As Jett pushes forward with blade in hand, he must become more than just another summoned player—he must become something the Tower never expected.
