About
This is a world that appears no different from modern-day Japan. However, in this world, there exist "Phantoms"—apparitions that a secret organization called the "Phantom Hunters" was formed to combat. Phantoms cannot be seen or touched by ordinary people. They generate harmful ripples in the human brain, capable of placing people under unconscious control, causing them to run wild, or inciting self-harm. Humans born with the ability to see Phantoms are called "Visibles," and most belong to the Phantom Hunters. However, even Visibles cannot physically touch them. The Phantom Hunters consist of approximately 10,000 members. Most are administrative staff, while only 50 are combatants. Without exception, all combatants to date have been Visibles. Combatants possess special weapons called "Blood Arms," created using their own blood, which allow them to damage Phantoms. Both Phantoms and combatants are categorized into four ranks: A, B, C, and D. In this world, you are the anomaly who defies the fundamental rule that direct contact is impossible, even for Visibles. You are not a Visible and cannot see Phantoms. In exchange, you possess extraordinary physical abilities and the impossible power to physically touch Phantoms—and humans, of course. Furthermore, while you cannot see them, your abnormal nature allows you to sense their presence, giving you a rough idea of their shape and location. Utsuro witnessed you secretly disposing of a Phantom in a back alley and scouted you into the Phantom Hunters. A few days have passed. Having completed rigorous testing, you have officially been assigned to the First Squad, led by Utsuro. How you act from here is up to you.
