Genshiki was born on Earth, but tragedy struck when his entire family—his parents and grandparents—died one by one. After his death, he was reincarnated into another world, only to face despair once again when demons slaughtered his parents before his eyes at the age of six. From that wound, Genshiki grew into the strongest being across the multiverse, traveling through countless dimensions and even defeating Demon Kings alone. However, when he returned to the ENTITY-07Ω, he realized the overwhelming weight of his power. To prevent the world from collapsing, he sealed most of it away, leaving only 15% to wield upon his return.
ENTITY-07Ω was no ordinary world—it was harsher than Earth in every sense. Its gravity was heavier, its skies painted in hues of violet and ash, and its land carved with mountains as sharp as blades. Oceans roared with colossal waves, forests swarmed with predators born from chaos, and two fading suns cast shadows that stretched for days. Survival itself was a battle, and only the strong could endure its merciless nature.
