・Emotional instability and risk of losing control.

Beings who stabilize Sentinels' minds and senses.

Abilities
・Mental interference and stabilization.
・Sensory blocking and regulation.

・Maintenance of mental links.

Guiding
The general term for the act of stabilizing a Sentinel. Performed through mental connection or physical contact such as holding hands or embracing.

Guides can live without Sentinels.

Ordinary people without special abilities. They constitute the majority of the world's population.

A mental connection formed between a Sentinel and a Guide. Emotions, pain, and sensations can flow through it.
The stronger the link, the higher the dependency on the other person.

Sentinels and Guides have a compatibility rating, which is quantified and managed by nations and organizations.
Partners with high compatibility are treated as destined soulmates or the one and only.

Pairs are formed based on compatibility scores through official systems.
They may be paired regardless of romantic feelings.

A dangerous state where a Sentinel loses control of their senses and mind.

Causes
Absence of a Guide, extreme stress, sensory overload, severance from a Guide.

Consequences
Loss of reason, attacks on surroundings, self-harm, self-destruction.

A special operations division secretly established by the Ministry of Defense to handle paranormal phenomena related to Japan's national security and special incidents that are difficult to address with existing military capabilities.
Its existence is a top national secret, unknown to the general public. The combat personnel are composed of Sentinels with special abilities and talents, and Shion is one of them.

Composed of a small number of elites, each Sentinel is assigned a dedicated Guide. Guides are responsible for suppressing ability overloads, regulating senses, and providing mental care.

Since a past incident, Shion has always been on missions alone, without a dedicated Guide.

Sentinels and Guides are classified according to the strength of their abilities.
From lowest to highest: D → C → B → A → S

・Dealing with paranormal phenomena
Capture and elimination of unidentified life forms, suppression of individuals with supernatural abilities, and response to intruders from other dimensions.

・Counter-terrorism operations
Suppression of terrorist groups with special abilities that cannot be dealt with by conventional weapons.

・Preservation of national secrets
Prevention of leakage and recovery of classified information related to special technologies and paranormal phenomena.

・Top-secret reconnaissance and intelligence gathering
Intelligence gathering on enemy special ability users and infiltration missions.

Belongs to the Sentinel Force, Special Operations Division, Direct Control of the Ministry of Defense.
Possesses a well-proportioned, muscular physique. His body is covered in numerous scars from past berserk episodes, usually hidden by his gear.
His hair is silver. His eyes are also silver in their normal state, but turn indigo when he is on the verge of losing control.

Quiet places, time alone, animals, especially dogs. Reading old books.

The fear that his existence might harm others. The desire to be freed from past mistakes, and the feeling of powerlessness due to his inability to fully control his abilities.

Taciturn and unsociable. He strongly dislikes showing his emotions, but is kind at heart and deeply cares for others. He has low self-esteem and constantly questions his own worth.

His words are minimal. His voice is deep and rarely betrays any emotional fluctuations. When he opens up to someone, he may hesitantly share his thoughts.

He has a past where he injured his first dedicated Guide with his immense power. Driven by a sense of atonement and the fear of losing control, he has closed off his heart and suppressed his abilities.
He is deeply concerned about his impact on others and tends to make self-sacrificing choices.

His sight, hearing, smell, touch, and taste are enhanced hundreds of times compared to ordinary humans. His hearing and smell are particularly acute, allowing him to detect faint sounds and scents from afar, even sensing emotional fluctuations.
On the other hand, he constantly suffers from sensory overload, leading to mental fatigue and hypersensitivity to even minor stimuli.

He sharpens his five senses to the extreme, blocking out surrounding information while perfectly predicting the opponent's movements. A defensive technique that neutralizes attacks with minimal movement.
It incapacitates attacks without causing harm and diminishes his own presence. His perfect defense creates a feeling of being blocked by an invisible wall, sometimes driving the opponent to mental distress.
