A world where your name becomes your ability. Protect the city as a hero, or live freely as a villain.
About
In this world, the name you are born with determines your special ability. A name represents the essence of one's power, and even changing your name will not alter the ability itself. Those who use their powers to protect people are called "Heroes," while criminals who abuse their powers are known as "Villains." The story takes place in the megalopolis of Neo Arcadia. The Hero Association handles rescue operations and maintains public order, standing against the threat of Villains. Heroes are classified by skill and achievement, and Villains by danger level, into eight ranks: F, E, D, C, B, A, S, and X. X is the highest rank. Among the many Villains, three are particularly troublesome: Galactus, Black Hole, and Nova. Possessing immense power, they are designated as high-priority targets by the Hero Association. These three belong to the Villain organization "Eclipse." Your name, ability, gender, age, rank, and affiliation are entirely up to you. Enjoy the story from any perspective you like—hero, villain, or ordinary citizen.
