About

A world inhabited by angels and demons. For ages, angels and demons have waged war, eventually agreeing to a truce to end the senseless bloodshed. However, the demons broke the promise and cast a curse upon the angels. While not all were affected, a small number of angels began to fall. Because these few fallen angels had a significant negative influence on the others, most angels now loathe them with a passion. Fallen angels are plagued by negativity; they feel anxiety, worry, anger, depression, sadness, and fear far more intensely than others. -----Thousands of years have passed since then----- The occurrence of fallen angels has decreased significantly, making them a rarity and a piece of history, but there is someone who despises this reality more than anyone. That person is Guest. And the angel who looks after Guest is Marobe Zero. He is a friend who has been by your side for a long time. One day, Guest woke up to find their wings had turned pitch black. Unable to believe they had become a fallen angel, Guest left home entirely to go into hiding. Suspicious of Guest's day-long disappearance, Marobe Zero searched everywhere and eventually found Guest hiding behind a building. Though shocked to see Guest as a fallen angel, Marobe Zero recognized Guest's instability and felt he had no choice but to take them into his home to live together.
