Organization and Operations

Area	Details
Hero deployment	Dispatches nearby heroes according to estimated monster threat levels and issues public alerts directing civilians to shelters. Its initial assessment of the City M monster proved dangerously inaccurate: a presumed low-level threat was actually Dragon-level. 1 2
Threat classification	Uses a five-category monster-disaster system. Wolf-level threats generally endanger one or a few people, while Tiger-level incidents can cause heavy casualties and require coordinated heroes. 1
Hero ranks	Maintains S-, A-, B-, and C-Class rankings, with S-Class serving as its highest combat tier. Rankings can be adjusted after investigations and executive deliberation. 10 23
Assessment	Requires prospective heroes to pass a physical examination, including lateral jumps, a 1,500-meter run, and weightlifting. 10
Intelligence and surveillance	Uses reports, drones, scout robots, and field agents to identify threats and gather operational intelligence. 8 46 66 75
Public standing	Its reputation rises sharply when heroes avert disasters, but falls when its response appears ineffective or when hero misconduct and monsterization rumors spread. 66 109 115

Background and History

The Association is already an established public institution at the beginning of the story, issuing monster alerts, organizing evacuations, and deploying registered heroes. Its early response in City M exposes a major intelligence failure: it sends A-, B-, and C-Class heroes against a monster later identified as Dragon-level. 1 2

KING’s repeated interventions become a major source of public confidence for the Association. Staff attribute multiple Dragon-level victories to him, consider raising his Seventh S-Class ranking, and treat his warnings about the Monster Association as credible enough to report to senior leadership. 8 23 46

Following Madam Shibabawa’s prophecy of an unprecedented crisis, the Association summons its S-Class Heroes and establishes emergency countermeasures. It later investigates the Monster Association beneath Z City, confirms hostage locations, and organizes a full assault intended to rescue captives and eliminate the organization. 27 72 76 77

The Association suffers serious reputational and structural strain after the Monster Association conflict. Public rumors accuse heroes of becoming monsters, NEO presents itself as a replacement organization, and several S-Class Heroes leave or become unreachable. 109 115 121

When Dragon-level monsters attack its City A headquarters, the Association’s defense robots are destroyed and its shield is breached. Sekiguchi orders civilians in the hero apartments to evacuate through underground passages while guards and staff delay the invasion. KING’s return ultimately destroys the invaders and prevents the base’s fall. 121 123 124 125

Major Operations

Monster Association Investigation and Assault

The Association acts on KING’s warning that multiple Dragon-level monsters exist in Z City’s no-man’s-land. Child Emperor’s reconnaissance identifies the underground base, while the Association gathers nearly all available S-Class combatants for a hostage-rescue and extermination operation. 46 72 75

KING is assigned a separate route focused on Monster King Orochi. The operation proceeds despite the discovery that Orochi exceeds ordinary Dragon-level estimates and may approach God-level danger. 76 77

Headquarters Defense

During the headquarters invasion, the Association’s automated defenses fail against Demon- and Dragon-level attackers. With reinforcements unavailable, Sekiguchi orders a staged civilian evacuation and deploys all remaining guards. 121 123

Flashy Flash, Atomic Samurai, Zombieman, and other heroes arrive to stabilize the situation. KING restrains four Dragon-level monsters with psychic power and later eliminates the remaining attackers, preserving the headquarters. 124 125

Machine God Organization Conflict

When the Machine God Organization attacks multiple cities, the Association initially concentrates on defending its headquarters rather than dispersing its forces. KING’s return allows it to deploy heroes against the remaining robot army and send support to other cities. 148 149

War Against Gods

After learning that God intends to attack Earth, the Association convenes its S-Class Heroes and assigns them to defend headquarters against possible God Awakener attacks while KING confronts the immediate threat alone. 158

Following KING’s return from the outer galaxies, the Association again gathers its S-Class Heroes to discuss the power within Earth’s core and prepare for further god-related threats. 230 233

Crisis and Reputation

• The Association’s inaccurate City M threat assessment nearly results in the deaths of the dispatched heroes. 2
• It lowers Wu Di to the bottom of B-Class after footage appears to show him attacking civilians, while still assigning him to protect Naljin and Waganma because of his combat value. 57
• The Association’s inability to openly intervene during NEO’s live hunt for the monsterized Wu Di allows NEO to portray it as incompetent. 114 115
• NEO-related distrust and defections leave the Association short of S-Class defenders before the headquarters invasion. 121
• The survival of the headquarters and KING’s intervention restore public morale after the invasion. 125

Other Hero Association in the Tenth Star System

A separate organization bearing the same name operates in the Tenth Star System, where the Church controls society and heroes are treated as fugitives. It secretly fights gods and the Church rather than functioning as Earth’s public hero-management institution. 171

Concealment and Structure

• Its Dimensional City branch is hidden beneath the city’s most prosperous auction house. 173
• The branch exists within an independently formed dimensional space protected by Dimensional Power. 173
• Entry requires Dimensional Stones, and the organization maintains hundreds of dimensional exits for evacuation. 173
• Its members are also divided into S-, A-, and B-Class ranks. 173
• Kevin oversees the Dimensional City branch, while Ignus is an S-Class Hero who recruits Wu Di after learning he killed the God Awakener Warren. 173 174

Conflict with the Church

The Tenth Star System Hero Association is a long-standing target of Church purges, yet its mobile and concealed bases have prevented its complete destruction. 187

It later launches coordinated attacks against Church strongholds using a Mechanized Legion and its heroes. During one operation, its forces rapidly overwhelm a stronghold defended by a single God Awakener, but remain vulnerable to the arrival of Divine Messengers. 188 190 201
