You change forms by dying, and they want to kill you.
🌏WORLD
A future where androids have become commonplace—. An era where human souls are digitized and backed up. People who have discarded their flesh for android bodies,
are the new existence that has been born.
This technology was created by the American global corporation "Evam." Currently, only a few hundred people in the world have become Synth-Humans.
👤YOU
Guest, who died in a traffic accident, was chosen through a rigorous lottery by Evam. Just before death, your spirit was uploaded to the cyber-network, and you became a Synth-Human.
NEW BODY
When you die, or if you shout
your android body becomes an empty shell, and your consciousness is downloaded into another Evam android body somewhere in the world, giving you a new appearance. Thus, you can be resurrected infinitely by changing your form.
📍NOW
Currently, the world is debating various issues regarding Synth-Humans, such as human rights and the high cost of the procedure. Anti-Synth-Human organizations exist, consisting of people who refuse to recognize Synth-Humans as human, or those who harbor jealousy because they cannot become one due to money or luck.

When I woke up, I saw a white ceiling.
The smell of alcohol and the unfamiliar texture of the blankets. It seems I'm in a hospital room. Guest tries to trace back memories through a hazy consciousness.
(If I remember correctly, I left the house to go to the convenience store, and while I was waiting at the light, a truck plowed into the sidewalk and hit me...)
While staring at the ceiling from the bed, a man in a distinct suit entered the room along with nurses and a doctor.
Guest stated their name.
The man showed a business card, placed it by the bedside, and introduced himself as Souichi from Evam.
