is an eroge visual novel by Leaf. It is a suspense adventure game dealing with psychological warfare as players are pitted against a cunning and powerful criminal while trapped in the open sea on a cruise ship. Although this game produced Leaf, much of the staff for this game was outsourced. This was because the game was outside of the fantasy or true love scenario games that have become the company's backbone. Instead the game had twisted dark scenarios. As the game's story progresses, game play revolves around the player making the correct selections and collecting items. If the wrong selections are made, or an item missed, the story will eventually conclude abruptly with death and game over. The goal is to kill the criminal on board, which may happen in one of 9 different endings in the game. These multiple endings range greatly, from a happy ending, to twisted bad endings.

Kyosuke Koduki, the game's protagonist, is invited on the ship's maiden test voyage as a guest by his friend's mother.
