"On Infinity"The concept of infinity in this work surpasses the infinities of real-world mathematics and set theory. Therefore, every infinity that appears beyond this point is greater than any infinity ever conceived in fiction or reality. It represents endless magnitude, length, and time without termination.
"Contained Verses"As all phenomena form the Omniverse, countless contained verses are continuously born within it. Whether they appear in the narrative or not, they continue to expand beyond even absolute infinity. These contained verses are not necessarily singular; they may consist of infinite hierarchical layers governed by the Omniverse, potentially forming structures so vast that lower layers collapse into nothingness. In this work, all existence forms the Omniverse, and within it, every scale and every infinite hierarchy exists as a contained verse.
"Universe"This refers to the universe in which Earth (Terra) exists. According to current science, most of the universe remains unexplained, though it is believed to have been born approximately 13.8 billion years ago through the Big Bang. Due to the influence of the Messiah, the structure of the universe has transformed into a network-like form, making its true nature currently impossible to fully comprehend.
"Multiverse"While interpretations vary, in this work the Multiverse consists of infinite universes existing outside a given universe, expanding beyond the concepts of infinity and set theory. These universes grow eternally without consistent rules. Some contain no Terra, some contain countless Terras, some lack planets entirely, while others consist only of stars. The lifeforms within them vary endlessly, including biological, botanical, energy-based, and gaseous beings.
"Metaverse"In this work, the Metaverse is defined as a collection of Multiverses. Infinite Multiverses gather infinitely to form a greater structure. This Metaverse also expands beyond infinity and set theory, containing limitless possibilities. Its inhabitants are akin to gods, capable of creating universes and generating life.
"Xenoverse"The Xenoverse is depicted as the collective structure beyond the Metaverse. These aggregates expand beyond infinity and set theory and contain vast possibilities. Within it exist higher conceptual entities representing the inhabitants of the Metaverse on an incomprehensibly larger scale.
"Omniverse"The Omniverse surpasses even the greatest conceivable mathematical space. It includes not only measurable structures but also imaginary universes that cannot be quantified, making it greater than Hilbert space. While the term originally implies "everything" as a singular existence, in this work the Omniverse exists beyond absolute infinity and continues to grow. It encompasses all imagination, all creations, and all conceptual worlds formed within the minds of intelligent beings. Individual thoughts become worlds; stories, music, illustrations, and architecture all manifest as universes. Even erased, forgotten, or uncreated ideas exist as worlds. These continue to multiply instantaneously. Beyond endlessly expanding Xenoverses, only after surpassing infinite conceptual growth does the boundary of the Omniverse begin to appear. It contains all life, non-life, possibility, impossibility, imagination, and non-imagination, across past, present, and future, transcending all logic, mathematics, and conceptual systems while continuing to expand eternally.
"Dimensions"Dimensions exist as hierarchical layers that expand beyond infinity, set theory, and logic. Lower dimensions collapse into nothingness. Dimensions themselves are conceptual and may exist as conscious entities. Within each layer lies an incomprehensible expanse beyond human understanding.
"Uncertain Infinite Domain"This is the black expanse where endlessly growing Omniverses exist. Only gods, Devils, the Dark Core (gods of Devils), and divine prophets may enter. Compared to this domain, the Omniverse is so small as to be nearly nonexistent. All mathematical, philosophical, and logical systems collapse here. It encompasses everything familiar—social media, messages, internet data, deleted information, games—as well as all forms of narrative and art, from novels and films to drawings and even a child's scribbles. It also includes all elements of reality: living beings, particles, theories, politics, economics, human thought, silence, and even nothingness. All phenomena form and contain the Omniverse within this endless myth. Beyond even this domain, there may exist unknown realms beyond all concepts, though no being is aware of them.
"Time"Time flows across all worlds and dimensions, though not uniformly. Some worlds experience time in reverse, from an end of nothingness toward a beginning of existence. The flow of time differs by dimension: first-dimensional, second-dimensional, third-dimensional, and beyond. Each additional dimension multiplies time infinitely, with higher dimensions experiencing slower progression than lower ones. As dimensional hierarchy increases, time diverges endlessly.
"Heavenverse"A realm of gods and angels, separate from the Omniverse. There exists one Heavenverse for each god, each infinite in scale.
"Hellverse"A realm separate from the Omniverse where Devils and the Dark Core reside. It is also the destination for those who commit sins or are rejected by gods. It expands according to the number of sins and continues to grow infinitely. Each Devil and Dark Core possesses its own Hellverse, each equal in scale to the Omniverse.
"Multidimensional World"A realm directly connected to all physical spaces, where time and space are ambiguous. Its inhabitants possess god-like abilities and can accomplish anything. This world is inhabited by beings equal to gods, who wage territorial conflicts. Its kings and warriors were historical figures in their previous lives.
"Astral World"When beings die, their souls (pure energy) leave their bodies and arrive here. It is also the destination for lifeforms that have evolved beyond physical bodies into astral entities. Though often called the spirit world, death is not an endpoint. Souls re-enter bodies, forming a continuous loop of existence.
"Parallel Worlds"At the beginning of time, universes interacted to generate new universes. At that moment, time began, but simultaneously branched into infinite layers of timelines, endlessly multiplying. Each branch contains alternate versions of existence, including different versions of oneself and Terra. These branches continue to expand infinitely, producing endless variations of reality.
