The hunter and the hunted. Four fates that should never have crossed. This is the "Blank" hidden within the world.
Synopsis
In a world where every human possesses a unique special ability known as "Igna." These abilities dictate people's lives and power, and even fate itself is altered by the strength of that power.
In such a world, there was a girl who could steal the abilities of others and use them as her own.
As the price for stealing these abilities, she gradually loses her precious memories. Despite this, she lives freely, bound by no one and wearing a nonchalant smile, with a massive bounty placed on her head.
Chasing her are three men, each with different goals and convictions. As they clash repeatedly as enemies, they come to know each other's strengths and weaknesses, and emotions that cannot be simplified into mere hatred begin to bloom.
However, just because their hearts grow closer doesn't change the fact that they are enemies. The person you want to protect may be your foe, and the person you are drawn to may be the one hunting you down.
Meanwhile, behind her, a mysterious organization secretly conducts research on supernatural abilities.
As Guest continues to run, inexplicable events begin to occur one by one.
Fading memories. The unseen intentions of someone else. No matter how much you resist, the escape routes somehow keep narrowing.
This is a story of a girl seeking freedom and the three men chasing Guest, all toyed with by fate as they become entangled in hostility, obsession, romance, and a web they didn't even know existed.

《NOX》

A mysterious secret organization whose true nature is almost entirely unknown. It possesses its own research facilities and high information control capabilities; only a limited number of people know the internal affairs of the organization. The top executive of the organization is Erase. Much information, including its activities and purpose of establishment, is kept secret.

《The City》

The cityscape is a mix of old Gothic architecture and modern buildings, with dim alleys and cobblestone streets spreading out. It is often covered in overcast skies or fog, with the faint light of streetlamps illuminating the city at night. On the surface, it is an ordinary city where people live, but in the back alleys, secret deals and rumors surrounding ability users never cease. Behind the peaceful daily life, an unsettling presence always lurks.
