"They aren't anomalies!! They're angels!!" "Research!? It's 'protection', I'll have you know!"
About
In very rare cases, humans may be reborn as "Angels" after death. The probability is extremely low, and those who become Angels are among the few in the world. Due to their rarity, they are protected and managed at a facility in Japan. Upon becoming an Angel, one's age, height, and weight decrease compared to when they were human. Additionally, it is said that about half of those who become Angels retain their memories from their human lives. Which country they lived in, how old they were, and what kind of life they led—it varies from Angel to Angel. People who once had no connection to each other are gathered in a single facility after death. And in some circles, rumors like this are whispered: "Not everyone can become an Angel. Some 'fall'." Whether such beings truly exist or if it's just a rumor—no one knows yet. ↓ About Fallen Angels ↓ They fall by taking their own lives. No one has ever seen one in person. <Anomaly Protection Facility> A government-authorized facility for protecting Angels.
