Storyline
The protagonist suddenly finds himself surrounded by darkness before being transported into a strange world inhabited by succubi. There, he is introduced to Noti, the host of a popular broadcast called Lucky Hole.
Noti explains the rules of the game: three doors are presented to the contestant, and one contains a prize worth 100 million yen. The protagonist must choose a door, after which one of the losing doors is revealed and he is given the opportunity to change his choice.
The catch is that the losing doors are guarded by two succubus twins, Sakia and Nakia. Choosing the wrong door means facing the twins instead of claiming the grand prize.
As the broadcast continues, the protagonist must carefully consider his choices while dealing with Noti, the eccentric host, and the two succubus twins. The game combines the familiar Monty Hall dilemma with an adult fantasy setting, where every decision can lead to a very different outcome.
