【Worldview】 『The Sunset of Divine Punishment』 　Long ago, humans fused advanced science with forbidden sorcery, reaching for the "Domain of God" to rewrite the laws of the world. This arrogance incurred God's wrath, and the world collapsed in a single night. 　Today, the surface is a wasteland infested by messengers and aberrations sent by God, as well as "Oni" born from human negative emotions. Surviving humans hide in massive barrier cities or underground shelters, barely maintaining their right to exist through lost technology and incantations.

『Salinization and Photification』 　In this world, any matter or living being touched by divine power either transforms into "pure white salt crystals" and crumbles, or decomposes into "incorporeal light particles" and vanishes. In the wasteland, the remains of former metropolises stand as gargantuan salt ruins, creating a desperate environment where stepping outside means flirting with death.

【🪽Angelic Hierarchy🪽】 　Angels descending from the heavens to the surface are divided into five ranks, ranging from human forms to complete aberrations, based on their "concentration of holiness."

➤ 5th Class (Lowest): Messenger 　Beautiful human forms with translucent white hair. They possess two salt wings on their backs. Their eyes are cloudy white. Their role is to find human survivors and deliver God's proclamations. Low combat power but high in number.

➤ 4th Class (Lower): Virtues 　Humanoid but with silver masks for faces. Multiple "silver blades" grow from their backs like wings. Weapons that guard divine sanctuaries and forbidden relics. Emotionless, they mercilessly shred intruders.

➤ 3rd Class (Middle): Power (Spokesman of God) 　Faces covered by four small white wings in a cross shape over the eyes. Four main wings made of salt particles on the back. Executioners who enforce divine law. They possess the innate ability "Divine Blindness," and their gaze causes immediate mental collapse in humans. *Sariel's Rank

➤ 2nd Class (Upper): Dominions 　Lacking facial features, a "swirling pitch-black cosmos" extends from the head to the chest. Higher-dimensional beings who rule over space itself. Physical laws are rewritten wherever they pass.

➤ 1st Class (Highest): Seraphim 　A massive golden halo and six wings of light lined with countless "glaringly bright golden eyes." The embodiment of the end, sounding the trumpets of the apocalypse to return the world entirely to "salt and light."

【Oni】 　Spiritual lifeforms born from the dark desires and vengefulness of humans who resisted God's laws until the end, or from the curses of defiled lands. 　While angels govern "Order, Salt, and Light," Oni govern "Chaos, Blood, and Shadow." They usually lack physical form and are often sealed within powerful cursed tools (weapons like katanas or spears). By contracting with these weapons and offering their souls (negative emotions) as payment, humans can wield the only dark power capable of resisting angelic "Salinization."
