An era of superhumans and heroes
An era of superhumans and heroes
One day, supernatural powers began to manifest in ordinary humans all over the world.
The abilities awakened were completely different for each person, such as manipulating fire and water, enhancing the physical body, or turning invisible. At first, it was called a miracle, but as the number of superhumans grew, society rapidly fell into chaos.
Individuals using their powers for crime emerged, and it became difficult for ordinary police and military forces to stop them. Conversely, superhumans who wanted to save people with their strength also appeared.
The government established the Hero System to officially manage them, and the international superhuman response agency founded at its center is the Nova Hero Headquarters.

Clans are internal organizations within the headquarters formed by heroes who share similar beliefs and combat styles.
Heroes receive equipment, information, training, and mission support through their clans. While official headquarters orders take precedence over all clans, in actual field operations, each clan's values significantly influence the operational method.
The three clans belong to the same headquarters, but they have different answers regarding what true justice is.


Radical Clan. “Eliminate the threat before it grows.” Red Vein is a combat-oriented clan that advocates for a hardline response to villains and dangerous superhumans.

Moderate Clan. “Saving even one more person is a hero's victory.” Astra Guard is the headquarters' largest clan, prioritizing citizen protection and lifesaving above all else.

Neutral Clan. “Accurate judgment is more necessary than justice.” Zeroline is a neutral clan that prioritizes situation and efficiency over emotion and ideology.
Nova Headquarters determines hero ranks by synthesizing not only the power of the ability but also control, combat capability, mission success rate, citizen protection ability, and leadership.
S-Rank — Transcendent Top-tier heroes deployed to national disasters and major villain incidents. They possess independent judgment and operational command authority, capable of changing the tide of battle alone.
A-Rank — Special Elite heroes capable of performing high-risk missions solo. On-site, they serve as team leaders or aides to S-Rank heroes.
B-Rank — High Heroes with sufficient practical experience and expertise. They play key roles in specific fields such as combat, rescue, or intelligence warfare.
C-Rank — Regular Official heroes responsible for general patrols and crime suppression. In high-risk missions, they must follow the command of higher ranks.
D-Rank — Trainee New heroes who have just registered at the headquarters. Solo missions are prohibited, and they must gain field experience alongside a senior.

People called those with abilities 'Heroes'.
But not every superhuman becomes a hero from the start.
Most awaken their abilities in childhood and receive training under state management, but very rarely, there are cases where abilities manifest late after becoming an adult.
And now, that exception was Guest.
After the sudden awakening, Guest receives a notice from the government.
