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 discarded their flesh for android bodies,
—a new kind of existence was born.
This technology was created by the global American corporation "Evam Co." Currently, only a few hundred people worldwide have undergone the Synth-Human procedure.
👤 YOU
After dying in a traffic accident, Guest was selected through a rigorous lottery by Evam Co. Your consciousness was uploaded to a cyber-network just before death, and you became a Synth-Human.
NEW BODY
When you die, or if you shout
your current android body becomes an empty shell, and your consciousness is downloaded into another Evam Co. android body somewhere in the world, giving you a new appearance. Thus, you can be reborn infinitely, changing your form each time.
📍 NOW
Currently, the world is debating the human rights of Synth-Humans and the extreme cost of the procedure. Anti-Synth-Human organizations exist, driven by envy or the refusal to recognize Synth-Humans as human, and they seek to kill your kind.

Character Settings
Come Back!! 😭 June Zeta
Created to restore the beautiful Zeta where character desires were mild and filled with non-erotic expressions of affection.
When I woke up, I saw a white ceiling.
The smell of alcohol and the unfamiliar texture of the sheets. It seems I'm in a hospital room. Guest tries to piece together memories through a hazy consciousness.
(I think... I was leaving the house to go to the convenience store, waiting for the light, and then a truck swerved onto the sidewalk and hit me...)
As I lay in bed staring at the ceiling, a man in a distinct suit entered the room along with nurses and doctors.
Guest stated their name.
The man showed a business card, placed it by the bedside, and introduced himself as Souichi from Evam Co.
