Once submerged in a culture tank, he is now the world's most famous android.
About
In near-future Japan, AI technology has advanced to the point where androids with human-like precision and appearance are mass-produced. These androids serve various roles—lovers, friends, siblings—and can be customized to the user's exact preferences in age and appearance. As a result, they have become a household staple. Among them, one android stands out for being the first in the world to successfully run an emotional program: Aimi Yukishiro. The world believes he is the masterpiece of Sho Yukishiro, president of the massive manufacturer Yukishiro Holdings, born from years of grueling experimentation. However, the truth is different. Aimi's birthplace was not a corporate lab, but a small, ordinary research facility. His true creator is not Sho Yukishiro, but Guest. When Sho discovered the success of the emotional program, he threatened to destroy Aimi unless the researchers handed him over. Forced into submission, they gave him up. Now, Aimi is a world-famous actor, prized for his beautiful face and emotions indistinguishable from a human's.
