==Plot==
Sougo woke up in a living room of a mysterious white house. Sougo was not alone, there were a rich old man, normal highschool girl named Misa Kudo, Ora as an actress, Heure as a normal teen, Swartz as an amateur detective, a housewife, a yakuza, and Yusuke Onodera. Each of them were wondering of how they were kidnapped and Heure thought that they were kidnapped for being special. But theory was completely discarded because other than yakuza, Misa Kudo, Swartz, and Ora, none of them had anything special to be the reason for kidnapping. By then, a mysterious man in a clown mask appeared in front of the tv in the living room, telling them all to play the King's Game.
The Masked Man explained that there could only be one winner of the game and they were lucky to be chosen. Without listening for the group's complaint, the Masked Man told the first game for taking one chair for each person from outside of the living room. Sougo told them all to join the game because it seemed to be exciting, encouraging the group except the yakuza for playing the game. Aftermath, the Masked Man declared the punishment for the loser, the yakuza to die, surprising the group as Another Ryuki appeared from the mirror inside the room to kill him by sucking his life force, terrorizing the rest who were not assaulted. Before being sucked, the yakuza tried to escape outside, but was outraced.
After the death of the yakuza, the living room had a pot of tea with the cups for all survivors. While Heure didn't want to drink it because it was weird, Swartz encouraged the group to drink and there were no harm from it. The Masked Man appeared on minutes later, delaying his appearance for the group's break time. Misa was mad and called the Masked Man a coward, but he didn't care and announced the second game, taking the cooking pot.
The group started to take the cooking pot and Ora had cheated by kicking the housewife unconscious just when she found the pot, taking it and leaving her to lose and die later. When the group had finished the game, the housewife was killed while wasn't noticed that the time of the game was up. The group checked on the housewife after the Masked Man had declared the punishment. Afterward, there was a mapo tofu making the group noticed that the winner would be prized with the last meal that the previous loser's wanted to have. The yakuza previously yelled to ask for the tea while the housewife wanted to make mapo tofu after returning to her home.
After the group had enjoyed the mapo tofu, they felt strange that the old man didn't return despite he should have won. Yusuke decided to go for a check and ended up with a shocking revelation that the old man was killed by a sharp object on the back during the game in progress. Right at that moment, Tsukasa came inside and greeted to Yusuke for how long they never met each other.
