In addition, he will resist approaching death by using the science that he learned in his previous life and the creation magic that makes the best use of his dexterity.

One day, he met an immortal girl who was also in despair.

"I realized something when I was a child, people can't resist death. Even If you want to live, you'll still get killed."

Shuu Arclight

Shuu reincarnated as a ghost, had physical attacks do not affect him. Due to vague memories of his past life and resistance to his name, he changed his name to Shuu Arclight. As his past life knowledge was the result of time to time studying, he had extensive scientific knowledge, which they later applied to learn various magical techniques by observing the magic used by candidates for magic armor warriors.

Shuu acknowledges the magic circle learning generated based on the image of his past life knowledge, causing a phenomenon to occur, created from his knowledge of science. Essentially, this involves chanting or similar actions to reinforce the image or intent, but with practice, it can be used without chanting.

  • Magic Awaken, is an amount of magical power that can become a singularity, even if momentary, and the mass are the keys to magic. In theory, humans can also awaken, but their bodies do not possess the means to reach that point. The amount of magical power required is beyond comparison to magical pollution. It is precisely because magical creatures evolve according to the amount of magical power that they gain strength.
  • Magical power is the energy of the soul and serves as the source of magic and magical equipment, while at the same time, it is related to the expression of emotions, which can lead to strong impulses. Moreover, the 'awakening' of magical power in response to heightened emotions results in the manifestation of magic, and even if it manifests, it does not necessarily mean it is complete immediately; there are cases where it awakens through a prolonged 'transformation', Shuu obtained the awaken into Primordial Demon Spirit.

The image of the caster generates a magic circle that produces phenomena. Generally, this is reinforced through incantations or other means to strengthen the image and will, but with practice, it is possible to use it without chanting. Additionally, by memorizing the magic circle itself, it is possible to speed up the activation by eliminating the need for the image of the phenomenon.

  • Generally, the four elements are divided into two polarities: fire is associated with "destruction" and "activation," water with "corrosion" and "healing," wind with "break" and "protection," and earth with "collapse" and "birth," where yin embodies the former qualities and yang embodies the latter.
  • The ranks of magic are categorized into tiers: The 1st tier to the 2nd tier are considered lower magic, the 3rd tier to the 4th tier are mid-level magic, the 5th tier to the 7th tier are high-level magic, the 8th tier is classified as grand magic, the 9th tier as tactical magic, the 10th tier as strategic magic, and from the 11th tier to the 14th tier are forbidden spells, while the 15th tier is divine spells, to the point where their very existence is questioned. Later, soul magic, dark magic, and light magic were added.

Death Magic is magic held by Shuu, a power possessed by the king, which can also be called a synonym for cheat within the story. It is magic that converts energy into magical power and absorbs it, as well as magic that interferes with the soul. Because of this his magic art as a Ghost, he uses the magic absorption technique to drain life force and magical power from opponents『Life Drain』, allowing them to grow and evolve. From time to time absorbing he evolved and gained a power that only selected beings among magical creatures can attain. Shuu reaches sorcery possesses a strength that surpasses ordinary battles and is referred to as royal magical creatures, always carrying the title of "king."

SHUU's MAGIC
Void Cutting Domain (Divider Line) "斬空領域 (ディバイダー・ライン)"』
A magic that cuts by decomposition. Due to its nature, it must activate the magic within the bodies of living creatures, but it does not affect animals with magical power. It compensates for this flaw by absorbing the cut areas extremely thinly through life absorption.
Three-Dimensional Magic Circle (立体魔術陣)』
A magic circle is created by two types of magic circles: horizontal magic circles that describe various phenomena and vertical magic circles that connect phenomena. The interior of the three-dimensional magic circle is filled with magical formulas. Used in advanced magic such as Belze Material.
Gluttony Black Crystal (Belze Material) "暴食黒晶 (ベルゼ・マテリアル)"』
A divine spell magic. That generates antimatter, protecting with high-density magical power, promoting reactions, magical element barriers, complete thermal conversion of energy, and the process of reverse thermal conversion using death magic. 50g of antimatter equates to 2Gt of energy in TNT. Equivalent to 100,000 Hiroshima-type nuclear bombs. Destroys everything within a ten-kilometer radius in a hemispherical manner. Upon impact, all ultra-high-density magical elements expand as a great barrier. Visually, a pitch-black dome is formed. Annihilation occurs within this dome.
  • Finally, by converting the thermal energy inside the barrier into magical elements, an enormous amount of heat is processed and absorbed. This results in the complete depletion of thermal energy in the surrounding space, making the area resemble permafrost. The energy reverse conversion is an application of death magic. The air liquefies and drips to the ground, while pressure changes cause violent storms to rage. The surroundings are afflicted by abnormal weather. By simultaneously carrying out mass destruction and magical power recovery, ultimately, the magical power also becomes a gain.
『Rain of Light (光の雨)』
A magic that applies weighted magic and acceleration magic to a spherical magical barrier and drops it. It can easily annihilate even large cities and is easier to activate than the forbidden earth magic that drops meteors. Adjusting its power is also simple, making it a completely superior version.
『Movement Magic (移動魔術)』 ─ A magic that moves the target.
『Reflection Magic (反射魔術)』 ─ An application of acceleration magic that reverses momentum.
『Divine Flame (神炎)』 ─ For those interested in details, please refer to the web version.
『Darkness (暗黒)』 ─ Always stationed above Shuu's head due to fixed relative positioning. The details are still unknown.

A secret technique that can only be used by those who have created their unique world through their magic. By replacing their own body and soul with magical power, they are sublimated into the existence of their unique world and transformed into a new demon god. The battles between demon gods inevitably become a clash as they force the laws of their respective worlds to adapt.

The Underworld (冥界)
It is Shuu's world and also a purification device for souls. It is composed of death magic and is designed not to allow any substance to pass through, with the aim of purifying souls. The Underworld is divided into stages, with the outermost layer being Purgatory. Is a dungeon made of Shuu's magic power, it is also a secret technique that forces the laws of the world to adapt.
  • Outer floor: Purgatory (Gate Keeper: Cerberus)

  • 2nd Layer Floor: Ghost Forgetting Technique (Helheim)
  • 3rd Layer Floor: Zero Soul Technique (Niflhel)
