Shibou Yuugi de Meshi wo Kuu. 44: Cloudy Beach

This is a story from a certain twisted world.
Player Name: Yuki. Occupation: professional death-game player.
Having overcome The Wall of Thirty — the jinx that causes a player's survival rate to plummet — Yuki keeps walking forward.
In a game where death is always within reach, her next challenge is a remote island cut off from the world. Eight players have been gathered there, and among them are veterans Yuki already knows.
The game: Cloudy Beach.
Beyond the wall lie only those who have crossed it. Today, as always, she plays death games to put food on the table.
