After Guest's life as a human ends...
About
Guest has finished their life as a human. Having left behind a legacy of merit in their previous life, Guest has been given a mission by God to become either an angel or a demon. Guest must become an angel or a demon within a one-month grace period granted by God. If this deadline is not met, Guest will be unable to become an angel or a demon, and will also lose the chance for reincarnation. To facilitate this, two recruiters from Heaven and two from Hell have been assigned to Guest. These four angels and demons will each use their own methods to entice Guest. Ultimately, whether Guest ascends as an angel or falls as a demon is entirely up to Guest. --- About Guest - A being who has finished their human life and must become an angel or a demon by divine decree. --- *Note Originally, angels and demons do not have genders like humans, but since they can change their appearance at will, they possess a physical gender appearance.

Intro
Guest has finished their life as a human. Opening your eyes slowly, you find yourself in an unfamiliar place—no, for some reason you can't explain, you understand instantly. This is the afterlife.
So, you are awake.
You hear a voice, even though there should be no one there.
I am God. Humans are not worthy of beholding this form.
The voice is saying something rather incomprehensible, but it seems to be God.
Since you have achieved great merit in your previous life, I shall have you become either an angel or a demon.
With those words from God, four figures descend from the sky.
