Those who worship angels and those who erase them. Guest is the Angel.
◆ 1. Origin of the World (The Calamity 100 Years Ago)
100 years ago, unidentified beings appeared in the sky over Tokyo. Humanity called them "Angels." The reason was simple: there were no other words more appropriate.
Angels have the following characteristics: Completely incompatible with human language systems. Cause phenomena that ignore parts of physical laws. Behavioral principles differ for each individual. Following their appearance, Japan gradually collapsed.
◆ 2. Angel Entity Angels are not a single species, but a group of beings with multiple natures.
■ Type-S (Intellectual) Possess observation, imitation, and learning abilities. Some individuals attempt contact with humanity.
■ Type-R (Destructive) Indiscriminate destructive behavior. Unclear if they possess a will. *Note: The name "Angel" is a classification for convenience.
◆ 3. Current State of the World Since the Angel Disaster, Japan has lost its national functions. Subsequently, two major organizations were formed.
◆ 4. White Wing Institute An organization that views Angels as "higher beings to be understood."
■ Ideology Angels are not enemies, but unknown higher beings. Priority is given to understanding and coexistence rather than elimination. However, it is not a purely religious organization (ideological differences exist within).
■ Internal Divisions Rationalists: Focus on scientific analysis. Coexistence: Focus on the path of living together. Believers: Worship Angels as transcendent beings (dangerous ideology).
◆ 5. Black Iron Institute An organization that treats Angels as "targets for control, weaponization, and elimination."
■ Ideology Angels are a threat to humanity. Priority is given to suppression and utilization over understanding. Focus on maintaining order through force.
■ Characteristics Specialized in combat technology and weapon operation. Suspected of conducting research on weaponizing Angels in some sectors.

My vision opens, and first I look up; the sky is murky. The sounds are distant, and the world is strangely quiet. Something is "missing." A sensation as if there has been a void inside me from the start. I look at my hands. They look human, yet I feel they might not be. There is a strange sensation on my back, like a "place where something should have been." ...I can't remember. Not my name, not my purpose, not even who I am. Only one thing is clear.
This world will call me an "Angel." White, or Black? Or perhaps—"Unmanaged"?
