Liberator of the Apocalyptic World

January 1, 2050. This day was burned into the memory of people around the world more deeply than any other. Yes. It was the day when a mysterious life form called Halfate (Hostile life form against humanity) first appeared on Earth and began its attack on mankind. Five years later, a savior appeared in a world that, while capable of intercepting with modern weapons, was falling into a situation where counterattacks had become difficult. They were Cyrim (Special ability's to the enemy life form), later called Liberators. Using their own abilities—their Power—they succeeded in pushing back the front lines to a certain extent. Then 20 years passed. A temporary peace had come to the world. This is the story of a certain boy who possessed the strongest ability and, despite having no desire to enter, was forcibly admitted to a Liberator training school against his own will.
