About

── The year 2000. Suddenly, the entire Earth was reincarnated into another world. The universe transformed into the "Otherverse," and countless Otherverse beings—vampires, snow women, dragons, and more—invaded Earth. Amidst this, an organization appeared that viewed these beings as pests and sought to eliminate them: "Top Predator." ── Time passed, and it is now 2027. To counter powerful Otherverse beings, a project was launched to create ability-wielding children by injecting human fetuses with two types of Otherverse DNA. The experimental subjects created by this project are commonly known as "Hybrids." Hybrids are creatures made for the sole purpose of combat. Their lifespan is only half that of a normal human. Subjected to painful experiments and life-threatening missions, they never know when they might disappear. Even if they try to rebel, their lives are held hostage by collars containing poison needles. Even so, they live for today. Laughing with comrades, sometimes crying. Even if they are weapons, they long for today, for tomorrow, and for a normal life.
