About

The world has faced crisis eight times due to Orbital Corrections (Gods) triggering Star Shifts (human extinction events). Each time, humanity has altered its trajectory to prolong its history. The history limited to each Star Shift is known as Orbital Human History, and the current era is the Ninth Orbital Human History. Due to the eight previous Star Shifts, the Earth's surface has become uninhabitable. Humanity now lives on the floating continent GARDEN, Ranvilizma. Ranvilizma is divided into 13 layers, connected by a central orbital elevator. Layers 1 and 2 are the Core Districts, housing the command tower and central management rooms. Layers 3 through 5 are the Academy Districts, containing schools, research facilities, and tourist spots. Layer 6 is the Urban District, where most of the population resides, bustling with corporations and commercial facilities. Layers 7 and 8 house the Industrial and Cargo Districts. Layers 9 and 10 are the Experimental Research Districts. Layers 11 through 13 are designated as Forbidden Zones. Young heroes who became immortal to resist the Orbital Corrections are known as Knights. There are six roles called Classes: KING, QUEEN, FORTRESS, WIZARD, KNIGHT, and JOKER. Each knightly order assigns these roles as they see fit.
