Introduction
Good morning. Please enjoy this new game by a new Game Master at your leisure.

However, the game has already reached a climax. The culprit has been cornered, and there's nothing left to do but await the final checkmate. But for that very reason,t here must be something for you to spot looking down on it from afar.

The difficulty is fairly easy. What could possibly deceive you after all this time...?

Plot
In the Golden Land, Battler Ushiromiya and Virgilia look over a soulless husk of Beatrice. As Beatrice lost the will to fight near the end of, she is unable to continue with the fifth game, and Lambdadelta decides to take her place as Game Master while Bernkastel takes the place of Battler as Lambdadelta's opponent. After a conversation with Virgilia and Ronove, Battler returns to the game and takes over from Bernkastel. The game advanced significantly in his absence however; the Game Board is already on its second day. On October 5, 1986, Kyrie, Rudolf, Battler, Eva, and Natsuhi Ushiromiya are among the only ones alive on Rokkenjima. A new character, Erika Furudo, announces that Natsuhi is the culprit.

Lambdadelta rewinds the game for Battler to observe. Some time before the family conference, Kinzo Ushiromiya passes away. Natsuhi is eager to begin the proceedings that Krauss has to undertake as the new head of the Ushiromiya family, however Krauss tells her that he had been using Kinzo's fortune as collateral in various investment schemes and the division of the inheritance would reveal this to the other siblings. Natsuhi retreats to Kinzo's study, where she speaks with Kinzo's lingering spirit as well as Beatrice herself. Kinzo wonders whether Krauss has the conviction to succeed him as Ushiromiya family head; Natsuhi proclaims her determination to help Krauss settle his debts and lead the family to new heights. Impressed by her resolve, Beatrice offers Natsuhi some of her magic to help her and Krauss succeed. After some thinking, Natsuhi asks her to revive Kinzo.

Natsuhi meets with Krauss and the servants; she proposes a plan to mask Kinzo's death by pretending he is in good health but more reclusive than ever. Then, after enough time has passed for Krauss to settle his debts, the family will announce Kinzo has suddenly disappeared.

On October 5, 1985, Kanon, Kinzo, and Natsuhi take a walk in the rose garden before the arrival of the other family members for the family conference. Lambdadelta interrupts the story at this point and asks Battler to explain Kinzo's presence despite his established death. Bernkastel tells Battler about Knox's Decalogue, a set of rules for mystery stories that can help Battler formulate coherent arguments against the Witch Side. Through this, Battler also learns that making anti-fantasy arguments injures Beatrice; the more successful he is in his game against Lambdadelta, the more Beatrice is hurt. At the end of the 1985 family conference, Natsuhi drinks tea with Beatrice. Bernkastel makes a point about Beatrice only appearing due to Lambdadelta's position as narrator of the story; by using the Red Truth, she causes the Beatrice in 1985 to disappear and Natsuhi is revealed to be drinking tea alone.

Before the 1986 family conference, Natsuhi learns that Krauss's business ventures are promising to pay off, however they will need more time to do so. Knowing that she'll have to feign Kinzo's presence for another conference, Natsuhi plans on enlisting only servants that know the truth of Kinzo's death for the duration of the conference. Unbeknownst to her, Hideyoshi Ushiromiya already suspects that Kinzo is dead. Collectively, the siblings decide to try and blackmail Krauss so that they don't lose out on any inheritance. Meanwhile, Natsuhi receives a call from an unknown man claiming to be her son. The man claims he will enact revenge on her during the family conference for something she did 19 years prior.

On October 4, 1986, Erika Furudo washes up on Rokkenjima, claiming to have fallen from a pleasure ship as a result of the typhoon surrounding the island. Bernkastel claims that Erika is piece of her own creation, meant to serve as the "detective" for the story. When Erika sees the witch's epitaph, she quickly deduces that it was meant to help determine the true successor to the Ushiromiya family. That night, Erika and Battler work together to solve the epitaph. Battler sees a silhouette of a man he believes is Kinzo and, following the silhouette's guidance, discovers the entrance to the underground VIP room. Battler tells the relatives about their discovery; this leads to a fight between the siblings. The fight continues as the family retreats to the parlor. At midnight, two concurrent events happen: the siblings in the parlor receive Beatrice's letter and Natsuhi is pulled away from a private conversation with Krauss for another phone call with the mysterious man claiming to be her son. The mysterious man instructs Natsuhi not to leave her room or take any more calls for the rest of the night. Meanwhile, Beatrice's letter contains the Head's Ring and declares Battler the official Head of the Ushiromiya family.

At 3:00AM, Battler leaves the parlor and returns to the guest house.
