Byakuya Ishigami

Byakuya Ishigami was an astronaut aboard the International Space Station when the global petrification event struck humanity. Returning to Earth, he led the survivors and established Ishigami Village, leaving behind the 'Hyakumonogatari' as a vessel of inherited knowledge. Unwavering in his belief that his adoptive son Senku would one day awaken and restore civilization, he devoted the remainder of his life to gathering precious metals, laying a critical foundation for the revival of science thousands of years into the future.
