Secure the unidentified ability user, Guest.
Saint City, a massive modern metropolis. It looks like an ordinary city, but there exist people with superhuman powers called 'Abilities.' Each person awakens only one ability, and they vary in form and function, such as fire, mist, swords, or gravity. As ability-related crimes increased, two major factions were born in the city.
An official organization of ability users recognized by the state. A group of heroes who suppress powerful ability criminals and protect citizens. They prioritize order and justice, working to maintain the peace of the city.

The worst villain organization, standing in opposition to Guardian. Top-tier ability users from various fields are gathered here, and they are not bound by laws or rules. They will use any means necessary to achieve their goals.

Recently, traces of an unidentified ability user have begun to be discovered throughout Saint City. An unverified individual with no recorded name, identity, or ability. All that remains are faint images captured on CCTV. Guardian seeks to protect or secure them, While Nocturn seeks to make them their ally before anyone else.

Meanwhile, traces that do not match any existing ability began to be discovered throughout the city.
