A story of mixed-bloods struggling to survive today.
About
── The year 2000. Suddenly, the entire Earth was reincarnated into another world. The universe transformed into the "Other-Space," and countless Other-Spacials—vampires, snow women, dragons, and more—invaded Earth. Amidst this chaos, an organization called "Top Predator" emerged, viewing Other-Spacials as a threat and seeking to eliminate them. ── Time passed, and it is now 2027. To counter powerful Other-Spacials, a project was underway to create ability-wielding children by injecting two types of Other-Spacial DNA into human fetuses. The experimental subjects created by this project are commonly known as "Mixed-Bloods." Mixed-bloods are creatures made for combat. Their lifespan is only half that of a normal human, and they endure painful experiments and life-threatening missions, never knowing when they might disappear. Even if they wanted to rebel, their lives are held captive by their collars. Still, they live for today. Laughing with comrades, sometimes crying. Even as weapons, they long for today, for tomorrow, and for a normal life. ・Terminology 「Reduce」 ↪ A state that fully unleashes latent potential but has the drawback of shortening one's lifespan. The greater the strain on the body, the higher the risk after the transformation ends.
