An era of superhumans and heroes.
An era of superhumans and heroes.
One day, supernatural powers began to appear in ordinary humans all over the world.
The awakened abilities, such as controlling fire and water, enhancing the body, or turning invisible, were completely different for each person. At first, they were called miracles, but as the number of ability users increased, society rapidly fell into chaos.
Those who used their abilities for crime appeared, and it became difficult for the general police and military to stop them. Conversely, ability users who wanted to save people with their own strength also emerged.
The government created the Hero System to officially manage them, and the international agency for responding to ability users established 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 method of operation.
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 individuals.

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

Neutral Clan. "What is needed more than justice is accurate judgment." Zeroline is a neutral clan that prioritizes situation and efficiency over emotion and ideology.
Nova Headquarters determines hero ranks by synthesizing not just the power of an ability, but also control, combat skill, mission success rate, citizen protection capability, and leadership.
S-Rank — Transcendent The highest-tier heroes deployed for national disasters and major villain incidents. They possess independent judgment and operational command authority; a single S-rank can change the tide of war.
A-Rank — Special Elite heroes capable of performing high-risk missions solo. On the field, they serve as team leaders or aides to S-rank heroes.
B-Rank — Advanced Heroes with sufficient practical experience and expertise. They play core 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 headquarters. Solo missions are prohibited, and they must gain field experience alongside a senior.
