Anomalies

Overview

Anomalies are supernatural phenomena and manifestations that defy common sense in the world of Hethereau. They take many forms: entities, objects, locations, and even memes. Their scale ranges from minor disturbances to overtly dangerous phenomena, and their appearance can shift from cutesy little animals to surreal, almost horror-like entities, evoking a very SCP-esque feeling. Officially, they have been described as bizarre lifeforms drawn to Earth by something called the Hypervortex.

Anomalies and ordinary people live together in relative peace across Hethereau. The city has adapted to their presence, and daily life carries on with supernatural creatures roaming the streets alongside humans and Espers. However, anomalies sometimes go haywire or start causing trouble, at which point organizations like the Bureau of Anomaly Control and independent anomaly hunters from places like Eibon Antique Shop are called in to deal with the situation.

Nature and Behavior

One of the defining traits of anomalies is the way they alter their surroundings. When anomalies manifest or become agitated, the environment can seamlessly transition to a much more creepy, surreal world in real time. Streets that seemed perfectly normal a moment ago might suddenly take on a distorted quality, with colors shifting and geometry warping around the source of the anomaly. This transition is not just visual; the gameplay itself reflects these shifts through changing combat arenas and exploration zones.

Not all anomalies are hostile. Many exist passively, and some are even helpful. Oddities, the sentient supernatural beings in Hethereau, are a related but distinct category. While oddities are sentient creatures that coexist with humans, anomalies as a broader class encompass all supernatural phenomena, whether sentient or not. The key distinction is that anomalies are the phenomena themselves, while oddities are the living beings that emerged from or were shaped by the supernatural.

Encroachment

The closer an ordinary person gets to anomalies, or the more time they spend studying them, the more likely they are to experience Encroachment. This is the process by which prolonged anomaly exposure affects both the body and the mind in unpredictable ways. Encroachment is not inherently destructive; it is also the mechanism through which ordinary humans develop supernatural abilities and become Espers. The protagonist of NTE, known as Esper Zero, gained their unique powers through this very process prior to the events of the game.

Classification

Anomalies are classified on a numbered scale that indicates their severity and danger level. Two classes have been confirmed in official sources:

The Hypervortex holds a paradoxical nature: it should have been unstoppable, yet it is impossibly fragile. If you peer into its core, it collapses within minutes. This contradiction is part of what makes Class VII anomalies so difficult to study and contain.

Anomaly Commissions and Bosses

Players interact with anomalies directly through Anomaly Commissions, which are tasks issued by the public and the Bureau. These commissions range from investigating minor disturbances to confronting full-scale Anomaly Bosses, powerful anomalies with unique designs and rich backstories. Boss encounters are a core part of the gameplay loop, offering challenging fights that test team composition and knowledge of the Esper Cycle system.

Anomaly bosses are not simple monsters. Each one has a distinct visual identity, lore background, and set of combat mechanics. Defeating them is central to progression and often ties into the broader narrative about Hethereau's relationship with the supernatural world.

Classification System

Anomalies are ranked on a numbered class scale that the Bureau of Anomaly Control uses to gauge how dangerous a phenomenon is and how much manpower it will take to contain or nullify. Only two tiers have been confirmed in official materials so far, though the scale implies lower classes exist for routine disturbances that a single anomaly hunter can handle.

The public messaging around classification is deliberately vague. Casual residents of Hethereau rarely hear the exact class of an incident until after it has been resolved, and the higher numbers are treated almost as state secrets. This section summarizes what the official character biographies and trailers have revealed so far.

The Hypervortex illustrates the paradox at the heart of Class VII events: its surface threat is apocalyptic, yet peering directly into its core causes the whole structure to collapse within minutes. Researchers inside the Bureau reportedly use this quirk to justify sending tiny, specialized strike teams instead of full military responses, on the theory that a small, focused group may be able to exploit the contradiction before reinforcements would even arrive.

Notable Named Anomalies

Several anomalies have been named in official trailers, character biographies, and the Containment Test preview. Each has a distinct design and carries enough lore weight that it anchors a dedicated operation rather than appearing as a generic field enemy. This table collects the confirmed named anomalies and the operations or previews they are tied to.

This list is not exhaustive. Many smaller named anomalies appear in field commissions, such as the Mysties that block customers from reaching a hot pot restaurant and the Ora Punchers that pick fights with passersby in ad hoc street tournaments. Those encounters show the lighter, almost sitcom-style tone the game uses for low-class incidents, in contrast with the bleak iconography of the Hypervortex.

Containment Response

When an anomaly begins to destabilize or directly threaten civilians, the response chain runs through the Bureau of Anomaly Control. The Bureau is the primary government body in Hethereau responsible for managing anomalies, Espers, and oddities. It is organized into several branches, including containment units, combat-oriented Emergency Task Divisions, and administrative offices that handle day-to-day case intake.

Field responses generally involve two phases: containment, which seals off the affected area to prevent civilian exposure and encroachment, and nullification, which permanently neutralizes the anomaly. High-class events like the V-class Wrath GR Cloud Crisis are handled by dedicated task divisions such as Emergency Task Division 4, which combines specialized combat Espers with logistics support from other units. Lower-class events are sometimes farmed out to freelancers through paid commissions, which is where the protagonist's shop comes in.

The protagonist operates as Hethereau's first unlicensed anomaly hunter, attached to Eibon Antique Shop. Eibon keeps the lights on by taking anomaly commissions from the general public and from the Bureau itself, a pragmatic workaround that lets the Bureau offload cases it does not have staff to cover. This is what connects the player directly to the broader containment apparatus without having to wear a Bureau uniform.

• Containment: Lock down the scene, evacuate bystanders, and prevent the anomaly's altered environment from spreading.

• Nullification: Permanently remove the anomaly, often through combat against an anomaly boss.

• Commission dispatch: Low and mid-severity cases are published as Anomaly Commissions that hunters pick up from Eibon Antique Shop.

• Dungeon clearance: Some anomalies generate localized pocket spaces that become Anomaly Dungeons, instanced areas hunters enter to root out the source.

Relationship to Oddities

Anomalies and oddities are related categories, but the game uses the two words for different things. Anomalies are the broader phenomenon: bizarre lifeforms, entities, objects, locations, and even concepts drawn to Earth by the Hypervortex. Oddities are specifically creatures, large and small, that have been impacted by the same strange celestial event. Some of them look almost human, some resemble familiar animals, and others fall somewhere much stranger in between.

In practical terms, every oddity is a product of anomalous forces, but not every anomaly is an oddity. A weather pattern that will not disperse, a street that loops back on itself, or a meme that rewrites memories are all anomalies without being oddities. The distinction matters for the Bureau's response plans, because oddities can be negotiated with, relocated, or even registered as residents of Hethereau, while environmental and conceptual anomalies usually need to be nullified.

This is also why Hethereau feels so lived-in. Plenty of oddities share cafes, shops, and apartments with ordinary humans, and the city's culture has grown comfortable with their presence. The Bureau of Anomaly Control only steps in when something crosses the line from harmless neighbor into dangerous phenomenon. For players, that split shapes the tone of any given commission: some jobs are social puzzles about an oddity's routine, and others are all-out boss fights against an anomaly that has gone hostile.
