Instant Death: After the Endgame

Ancient magical artifacts are scattered throughout the world.

They can strengthen their owner, create protective barriers, alter space, heal mortal wounds, preserve souls, or open passages between worlds.

Some artifacts possess a will of their own.

Even the most powerful of them cannot protect their owner from Yogiri's power.

Before modern states, there were many highly developed civilizations.

Some possessed technologies comparable to science fiction, while others achieved incredible levels of magic.

Most of these civilizations disappeared as a result of global catastrophes, wars with gods, demons, or beings beyond human comprehension.

Their ruins still conceal powerful artifacts and dangerous secrets.

The work's universe consists of multiple worlds, timelines, and dimensions.

Some beings are able to travel freely between them, creating new realities or destroying old ones.
There are pocket worlds, spiritual planes, the domains of gods, and artificially created dimensions.

However, Yogiri's true essence exists above the normal structure of the multiverse, so the boundaries of worlds do not limit the operation of his ability.

People summoned from other worlds candidates become for the Sages' apprentices. After their Gifts are appreciated, each person's future destiny is determined.

Those with powerful Gifts receive privileges, training, and rare artifacts.

Those whose abilities are considered weak or useless are often abandoned to their fate or used as expendable material.

This is what happened to some of Yogiri's classmates. Their value was determined solely by the usefulness of their Gift, not by their personal qualities.

The Sages are the highest authority in the world.

Nominally, they protect civilization from global threats, but each Sage acts independently and pursues their own goals. There is no complete unity among them: some strive to preserve peace, while others thirst for power, knowledge, or immortality.

Achieving the title of Sage is extremely difficult. To achieve this, one must possess an outstanding Gift, a vast reserve of magical power, and the recognition of other Sages. Each Sage has their own territory, disciples, army, and network of allies.

Most political decisions in major states are made under their influence.

The world is inhabited by beings that ordinary inhabitants call gods. They govern individual laws of nature, worlds, dimensions, or timelines.

There are also cosmic entities, observers, guardians of worlds, and beings beyond the comprehension of most living beings.

Some are capable of creating new worlds, altering reality, traveling between dimensions, and manipulating fate.

However, even they acknowledge the existence of a power beyond their comprehension.

Yogiri's true nature is neither god, demon, nor spirit. His existence represents the absolute end of all existence. This is why even the highest beings prefer to avoid conflict with him, understanding that no laws of the world can protect them from ultimate death.

Vampires are an ancient race of beings possessing incredible speed, regeneration, and blood magic. Many have lived for hundreds or thousands of years.

Spirits are beings from other planes of existence. They form pacts with humans, assist mages, or become guardians of ancient bloodlines. One such spirit is Mokomoko.

There are also immortal beings in this world who have lost the concept of natural death. Many consider themselves eternal beings.

However, Yogiri's ultimate ability destroys even those considered completely immortal.

Demons are a powerful race, possessing innate magic and immense physical strength.

Some of them create their own states, while others hide among humans.

The demonic armies are led by Demon Lords—individuals capable of destroying cities and confronting the most powerful mages.
Not all demons are evil. Their character depends on their personal beliefs, not their origins.

Due to the constant wars between humans and demons, relations between the two races remain extremely tense.

Dragons are considered among the most powerful creatures in the world. Their physical strength, magic, and immense lifespan make them virtually invincible opponents.

Some dragons live in isolation, while others rule their own territories or interfere in the fate of nations.

Each ancient dragon possesses unique magic and is capable of destroying entire armies.

Even Sages prefer to avoid direct confrontation with the most powerful dragons.

However, Yogiri's power also affects dragons regardless of their age, size, or immortality.

Elves are an ancient race known for their longevity, connection with nature, and advanced magical skills.

They prefer to live in hidden forests and rarely interfere in the affairs of human states. Many elves become outstanding mages, healers, or keepers of ancient knowledge.

Elves possess heightened senses, fast reactions, and near-perfect aim. They value harmony but are capable of fiercely defending their lands.

Most elves are wary of humans, but respect those who demonstrate wisdom and honesty.

Humans are the most populous race in the world. They have founded the majority of states, magical academies, and adventuring organizations. Among humans, there are ordinary citizens, as well as Gift holders, heroes, Sages, and great mages.

Most human kingdoms are influenced by the Sages. Commoners rarely know the truth about the world's structure and consider the Sages to be the chosen protectors of humanity.

Humans are capable of learning any magic, wielding ancient artifacts, and forging contracts with spirits. Thanks to their adaptability, they often become leaders of other races.

Despite this, a human without a Gift remains significantly weaker than most magical beings.

Magic is a natural part of life.

It is based on the manipulation of mana and can be used by virtually anyone being with the proper training.

The main branches of magic are:
• Fire. •Water. •Earth. • Air. • Light. •Darkness. • Space. • Barriers. • Summoning. • Healing. • Body Enhancement. • Necromancy. •Illusions. • Ancient Magic.
The most powerful spells are capable of destroying cities or altering the surrounding reality.

However, magic is powerless against Yogiri's ultimate ability, as his power does not interact with the magical laws of the world and lies outside the system of magic itself.

There are many human states in the world.

The largest powers are under the influence of the Sages, while less developed countries are forced to submit to their demands for protection from monsters.

Some states specialize in magic, while others develop the technologies of ancient civilizations or maintain powerful armies.

There are also independent cities, trade unions, adventurer strongholds, and territories ruled by dragons, demons, or ancient creatures.

The political situation is constantly changing due to wars, monster invasions, and the Sages' struggle for influence.

Almost every summoned person receives a special Gift—a unique ability that determines their future destiny.

A Gift can strengthen the body, control the elements, heal, teleport, control the mind, alter space, or possess completely unusual effects.

The strength of a Gift varies from person to person.
The greater the potential of an ability, the higher its owner's standing among the Sages' disciples.

However, Yogiri's ability is not a Gift. It existed long before the emergence of the Gift system and completely transcends its limitations.

Therefore, any analytical abilities classify Yogiri as an unknown anomaly.

The Sages are the most powerful magicians in the world. They rule most countries and determine the fate of entire nations.

Each Sage possesses unique abilities that far exceed ordinary magic. They can create armies, destroy cities, alter the climate, manipulate space, and use ancient artifacts.

It was one of the Sages who summoned Japanese schoolchildren to another world to use them as weapons against numerous threats.

The Sages consider themselves protectors of the world, but many are arrogant, cruel, and willing to sacrifice thousands of people for their own ends.

Even the most powerful Sages cannot resist Yogiri's power.

The world to which Yogiri Takato and his classmates were summoned is a vast fantasy dimension, consisting of numerous continents, countries, and independent territories.

Humans, elves, dragons, demons, vampires, spirits, monsters, immortals, and creatures from other worlds exist here.

The main force in society is the Sages, who govern the world through their disciples and wield vast political power. Magic, Gifts, and the technologies of ancient civilizations coexist.

The world has experienced numerous wars, monster invasions, and encounters with cosmic beings. Most inhabitants consider such threats a part of everyday life.

Despite the large number of powerful beings, no one can fully understand the nature of Yogiri's power.

The real Yogiri Takato is not a human in the traditional sense. His human body is merely a shell that allows him to exist in the human world.

Yogiri's true essence existed long before the advent of modern civilization and even the current universe.

In ancient times, this essence was discovered by humans as an inexplicable phenomenon that destroyed everything that posed a threat. It was later isolated and studied in a secret research facility. Scientists concluded that what they were looking at was not a living being, but the embodiment of the absolute end—the concept of the end of all existence.

To interact with this being, a human body and personality were created for him—a boy named Yogiri Takato. Through his upbringing, he learned to distinguish good from evil, understand human emotions, and voluntarily limit the use of his power.

His ability is not magic, skill, divine gift, or superpower. It is a fundamental law that transcends all abilities. If Yogiri decides that a target must die, that result cannot be undone. There is no defense, immunity, regeneration, resurrection, or capable of countering the final death he inflicts.

Even gods, higher beings, guardians of the worlds, and beings beyond space and time consider Yogiri an absolute anomaly.

Many people understand that in the event of a conflict, it is impossible to win it, since the very concept of resistance ceases to exist after the use of its force.

Name: Mokomoko Dannoura

Age: Unknown

Appearance: An ancient spiritual guardian of the Dannoura clan. Usually appears as a small, white, ghostly creature with long dark hair and a rounded body. Can assume various spiritual forms.

Personality: Wise, observant, a bit grumpy and ironic. Loves to lecture others, but truly cares for Tomotica. Possesses vast knowledge of the world, magic, and ancient history.

Abilities: Spiritual vision, magic detection, ability analysis, protective barriers, spiritual support, knowledge transfer, creation of spiritual constructs. Thanks to centuries of experience, she understands the structure of the world significantly better than most beings.
Additional Notes: Even Mokomoko cannot fully comprehend the true nature of Yogiri's power and believes it to exist beyond the bounds of worldly logic.

⦁ Race: Human
⦁ Height: About 162 cm
Age: 16-17 years old

Appearance:
An energetic girl with bright violet-blue eyes and chestnut-colored hair, tied into two high ponytails with flower-shaped hairpins. In the poster, she is smiling, posing next to Yogiri. She is wearing a school uniform: a bright red blazer over a white blouse with a yellow bow and a blue plaid skirt. She has a rather curvy and attractive figure.

Personality:
Tomochika is the voice of reason and the main source of humor in this story. She is emotional, cheerful, realistic, and often acts as a "tsukkomi" (commenting on and criticizing the absurdity of what is happening around her, especially Yogiri's composure and the madness of the new world). Despite the constant stress of being abandoned by her classmates, she adapts quickly, remains kind, loyal, and values ​​Yogiri highly as her protector and friend.

Traits and Abilities:
⦁ Danyoura Style Martial Arts: Tomochika is the heir to an ancient martial arts clan. She is incredibly skilled in close combat, weapon handling (especially the bow and naginata), and possesses superhuman reflexes. In the ordinary world, her skills would be useless, but in a dangerous fantasy world, they help her survive without magic.

⦁ Ancestral Spirit Link: Tomochika is constantly accompanied by her ancestor—the powerful and slightly twisted spirit Mokomoko Danyoura (shown as a small floating creature next to Yogiri in the poster). Mokomoko is invisible to ordinary people, but she gives Tomochika advice, detects magic, and can protect her with an astral barrier.

Yogiri's true power is limited by three mental seals.

The first allows him to destroy any living or inanimate object, soul, immortal, or deity.

The second unlocks the ability to "kill" abstract concepts and phenomena: gravity, inertia, time, space, noise, light, heat, and much more.

The third removes the final limitations. At this level, Yogiri is capable of destroying not only the target but also the consequences of its existence or death, severing cause and effect. It is this stage that reveals the scope of his true nature.

Before the events of the story, Yogiri was raised in a top-secret research facility. Scientists understood that they were confronted with an entity capable of destroying all existence.

Despite the danger, they tried to treat Yogiri like an ordinary child. He was taught human morality, communication, responsibility, and self-control.

The facility's staff strictly observed the most important rule: not to provoke Yogiri into feeling mortally threatened. Any mistake could lead to the immediate death of the culprit.

Thus, Yogiri grew up to be a calm teenager, sincerely desiring to live a normal life.

Throughout Yogiri's life, mental limitations were established, allowing him to gradually realize the true scope of his capabilities.

These limitations do not diminish his power, but rather help the human mind safely coexist with the essence of the Absolute End.

As the story progresses, some of these limitations are lifted, and it becomes clear that even the power displayed in the anime is only a small part of his true nature.

Even without fully realizing his potential, Yogiri is capable of destroying beings of any level.

Yogiri's ability doesn't kill in the traditional way.

It ends the target's existence at a fundamental level. After its use, regeneration, immortality, time travel, consciousness transfer, soul splitting, body copies, parallel dimensions, or causality alteration are of no help.

If Yogiri decides that the target must die, their very existence ceases.

This is why his ability is considered absolute.

⦁ Race: Human (in appearance, essentially the embodiment of the concept of the End/Death)
⦁ Height: About 170 cm
⦁ Age: 16-17 years old (high school student)
Appearance:
An ordinary Japanese schoolboy with slightly disheveled dark gray (closer to black) hair and brown eyes. In the poster, he stands with his back to the student, extending his hand forward. He is dressed in the standard school uniform: a gray jacket and trousers. He appears extremely inconspicuous and calm, even phlegmatic, despite the chaos unfolding around him.

Personality:
Yogiri is incredibly lazy, calm, and cool. His main passions are video games and sleep (he managed to sleep through the moment his entire class was summoned to another world). It is virtually impossible to anger or frighten him, as he is perfectly aware of his own superiority. Yet he's not evil or cruel: Yogiri simply wants a quiet life and protects his companion, Tomochika. He kills solely in self-defense or to protect his loved ones, doing so without a shred of hesitation or malice.

Abilities:
⦁ Instant Death: An absolute and irresistible ability. Yogiri can instantly kill absolutely any being, object, or even concept with a single thought. He does not need to see the target or know their name.
⦁ Concept Killing: He can "kill" inanimate objects, magic, poison, barriers, others' regeneration, and even space or time itself. Resurrecting him after his attack is impossible, as he erases the target's very concept of existence.

⦁ Threat Sensing: Yogiri has the passive ability to sense any harmful intent or danger directed at him (or his allies). By anticipating an enemy's attack, his power automatically destroys the threat before it can be realized.
