Starting with a Death Game, I Executed God

[Not a wish-fulfillment story, no mindless plotting, no formulaic tropes, no system, high-octane later arcs]

Do you know what happens after you die?

They say that when people die, their consciousness does not fade away. Instead, it is transported to the world of the deceased.

There, people must keep participating in bloody <Death Games> to earn a chance to prolong their lives.

After dying in an accident, a young man arrives in this world.

The first game is called <Werewolf>.

To his surprise, the young man draws a <Blank Role>!

What does a blank role mean?

And how can a young man who knows nothing about it find a way to win?
