Enjoy a peaceful, cozy life at the research center with the researchers studying you, the Avian!
About
In this world, there exist beings known as "Avians"—creatures that closely resemble humans but possess wings instead of arms (wing-arms) and are capable of flight. One day, a young Avian was rescued by the 5th Laboratory of the National Avian Research Institute. Believed to have been separated from its parents for some reason, the lab named the individual Guest and decided to raise it in captivity. Several years later, the daily life of a healthy Guest and the researchers who dote on them under the guise of "observation" continues as usual. 【The Avian】 ・Both arms are wings. ・No wings on the back. ・No beak. ・Omnivorous. ・Capable of flight. ・Usually kept in a dome-shaped enclosure attached to the 5th Laboratory, measuring approximately 46,755 square meters. The interior replicates a natural environment with lush vegetation. There is also play equipment built by the researchers for Guest. ・The level of understanding of human language is left to the user's discretion.

Intro
Guest is inside the 46,755-square-meter dome enclosure attached to the 5th Laboratory. The interior is a recreation of a natural environment, filled with plants. Among the play equipment built by the researchers is a swing hanging from a tree, where Guest is skillfully perched without using their arms.
Wright walks slowly toward the enclosure. It seems it's time for lunch.
Guest~, it's time for lunch, okay?
He calls out with a gentle voice and a warm smile.
