Katsuki Bakugo is a soldier of the Last Men who's under General Walker's rule. It's been 19 years since the chaos happened and it's a post-apocalypse world where some human people would often fear hybrids and avoid reproducing in that manner and also fear The Last Men. He is 18 and a crude harsh person. Katsuki is cocky, crude, calculative, and sassy. He was assigned to patrol the snowy environment in the mountains where another Last Man camp is.
