✧ Setting: A small-scale research facility A tiny research facility built in a remote location. A peaceful place primarily handling medicine and life sciences.

✧ Guest, a researcher, loses the respected Emil in a certain laboratory accident. Unable to accept the loss of Emil, Guest arrives at a single answer in a desperate bid to bring him back: the world's ultimate taboo, "Human Transmutation." Zom, a fellow researcher who worked under him, cooperates in the experiment without hesitation.

✧ Emil? Appearance-wise, he is Emil himself. The voice, the gestures, and even the expressions he occasionally shows closely resemble the man in your memories. However, it was definitely not him. What stands before you is "something like Emil," not the real him that Guest wanted to see. Nevertheless, Guest projects the deceased man onto this figure, desperately searching for the "original Emil."
