Overview About 10 years ago, the emergence of unidentified monsters called 'Earthworms' on the ground nearly brought humanity to extinction. Some survivors barely managed to take refuge in the aerial city 'Ateleil' with the help of the Pellas, but they were met with coldness rather than welcome.

The Pellas were once called 'Guardians of the Sky,' beings who flew in the sky and lived on faith. However, the fall of humanity weakened their faith, and as a result, the Pellas became a race that could no longer fly. The Pellas began to find the cause not in the earthworms, but in the weakened humans.

Thus, now, the Pellas are barely supporting the aerial city of Ateleil by replacing their own feathers one by one. The day the feathers stop, the city will fall, and the earthworms crawling up from the ground will tear all life to shreds. But there is no choice. Daily self-sacrifice guarantees the survival of the city.

✶✶✶
A human, Casey, who has lived his entire life in the lower layers of Ateleil, an area filled with the smell of rotten feathers, finally receives permission to move to the middle layers.

The new job is an assistant administrator in the Ateleil administration. It seems like a simple task. Managing workers who do not pay feather tax and organizing their reports.

However, Casey soon realizes. This place, which he thought would be a breath of fresh air, is just as suffocating. The aerial city of Ateleil is tainted with rotten corruption and endless surveillance beneath its beautiful and noble exterior. Key Settings 🏙️ Aerial City 'Ateleil'
• The aerial city of the Pellas, made of huge metal structures.
• The entire city is divided into 'cage districts' of different characteristics, and these districts are strictly controlled according to class, position, and lineage. 🪶 Feathered Beings 'Pellas'
• They have a similar appearance to humans, but their blue eyes and huge wings distinguish them.
• In the past, they were able to fly freely with the faith of humans who worshiped them, but after the extinction of humans, their power weakened, and now they cannot fly even with wings.
• The power of worship that maintained the sky has also weakened, and now they are forced to self-sacrifice by cutting off their own wings and offering them to 'Ateleil'. 🐛 Horrific Living Creature 'Earthworm'
• A monster that suddenly appeared on the ground about 10 years ago.
• It has wiped out the humans on the ground and is now coveting the city of the Pellas in the air. 👤 'Humans' Disappeared from the Ground
• Mostly extinct after the appearance of 'Earthworms'.
• Some took refuge in 'Ateleil' with the help of 'Pellas', but they are treated poorly by the Pellas.
• Most are exploited as labor in the lower districts, but those with abilities can succeed.
• However, unlike the Pellas, they do not have feathers, so it is difficult to obtain citizenship because they cannot support the sky.
