Byouki User
How cool. You really are cool. Ha ha. I’m not even being ironic, mister. Our industry is full of powers that break the rules, so it’s super cool that you can live there like some kind of samurai! I could never pull it off. I’m hopeless. Completely hopeless. Everything about me is hopeless. I’m trying to do a good job and I have the best possible plan in my head, but it never works out. It all crumbles away in the end. So, y’see… Ha ha. So I can’t hold back here☆ I won’t be safe unless I kill you.

Notable Attacks/Techniques:

  • Byouki: The Byouki is a cat Youkai from the continent that was created in a Kodoku ritual, a powerful curse made by placing countless poisonous insects and dangerous beasts in a single jar and having them kill each other. Its primary power is to apply a variety of diseases to whoever it possesses.
    • Melting Humans: The Byouki User can use her Byouki powers to dissolve/melt people down to the bone. She implanted her Byouki into the other members of her organization so that it automatically activates and kills them if they decide to reveal the organization's secrets.
    • Toori-Ma: The term “Toori-Ma” is used to describe normal criminals in modern times, but it originally referred to a paranormal phenomenon. A Toori-Ma is believed to possess people and cause them to commit unthinkable crimes. As a type of Toori-Ma, the Byouki can possess people by entering their shadow, drive them insane and reveal their violent side by making them kill indiscriminately. Those affected by it will enter a berserk state and attack anyone who gets close. This can be used in conjunction with a special search system to remotely target someone using a radio interception program, though this system requires something to lock to, such as the electromagnetic waves sent out by a vehicle’s robot brakes.
      Byouki Army

      The Byouki User and her army

    • Shadow Army: Even if she doesn’t manually set it up, her Byouki will find its own targets. It will scan her surroundings and search for whoever she considers an enemy and automatically produce the quantity and quality of Byouki needed to defeat them. When the Byouki is activated in this manner, dark shadows sweep out in every direction from the Byouki User’s feet. The shadows instantly swallow up the entire surface of the ground. The covered surfaces seem to throb and pulse before countless shadow copies of the Byouki User rise from the ground. She can create tens of thousands of copies to form an overwhelming army in an instant. She easily replenishes the losses suffered by her army, as shown when Illness Magic User managed to cut down five hundred copies only for her to instantly create one thousand more. The stronger her enemy is and the fiercer it fights against the army, the more Byouki will be produced and the stronger they'll be. This will continue until the Byouki wears down the enemy with its endless numbers and tears them to pieces. However, external interference will disrupt the Byouki's equation and may create a gap in her army.
      • Cursed Claws: Each of the shadow copies is a symbol of disease and pestilence. A scratch from one of their long claws will cause one’s entire body to foam up, rot away, and have its protein boiled from within by an intense fever.
