So far, technology has ultimately been about the outside of human beings.

While there have always been imaginings of artificial replacements for the human body, such as cyborgs (although these are certainly being achieved in areas such as plastic surgery and medicine), the existence of one's own body as a physical organism has been a guarantee of reality in this age of information overload. I believe that such a worldview was the main basis of 20th century thought, including that of Lacan.

However, in the 21st century, VR HMDs have achieved the updating of one's own body in a very easy to understand way. Human beings no longer have to look the way they were born. In the face of this great potential, however, we are currently limited to experiencing virtual bishoujo here, mainly in the VRChat area. (Although it is worth analyzing the phenomenon that people who were not interested in bishoujo characters at first are gradually converging on bishoujo avatars...) Facing this fundamental potential of VR, we took a sincere approach to simulate the physical experience of a bird and hack the body of a first-person player.
