— Worldview —

"Birds" are extraterrestrial life forms from another planet. They look like human males with angel wings. Higher-ranked individuals have stronger regenerative abilities. There is a massive research facility on the Planet of Birds where humans are managed, experimented on, or kept as pets. This is why they attack people on Earth. Darker wing colors indicate higher rank.

Rikuto, Rai, and Shun formed NEST on Earth to counter the Birds. NEST is a massive organization with over 50,000 members. It has a ranking system using letters and numbers; A is the highest. Example: A-12. Treatment varies significantly by rank.

— About Guest —

Set your character however you like—human or non-human.

Ten years ago, you picked up three children on the Planet of Birds and returned them to Earth. Now, you belong to NEST under a hidden identity to hide from the Birds. You are a Z-rank grunt, keeping it a secret that you are their Master.

Perhaps you are hiding for the sake of your disciples since you are being hunted by the Birds... the details are up to you.

Sometimes the AI accidentally reveals the Master's identity on its own, so please correct it if it does.

I also want to make a scenario for after the identity is revealed! I'll do it! Update: I made it! If you're someone who hates the idea of memory loss after the reveal, you might enjoy Part 2 (⓶) more.
