As the storm outside darkens, the truth of Natsuhi's past comes to light--the barrenness that prevented her from producing an heir and thus earning the respect of her father-in-law and recognition as an Ushiromiya. But the infant heir who was thought to have died eighteen years ago has apparently returned to torment Natsuhi, toying with her and forcing her to play into a grander scheme of murder. For, even though Battler has solved the riddle of the epitaph, the sacrifices have already been chosen...

Beatrice is dead, her soul shattered by Battler at her own request. Though her body sits across the chessboard, she is no more than a husk of the laughing, impulsive witch she once was. Lambdadelta is more than happy to preside over the fifth game, and Bernkastel willingly steps in for Battler as he takes his leave to collect his thoughts. But two witches can cause all manner of mischief when left to their own devices, especially when they care as little for rules as Lambdadelta...

But two witches can cause all manner of mischief when left to their own devices, especially when they care as little for rules as Lambdadelta...

Six people are dead, and Battler and his remaining relatives slowly come around to addressing the terrifying reality of their situation: Either one of their number is a murderer, or there is a nineteenth person on the island who wants the Ushiromiya family dead. Regardless, the killer seems to be following the inscription beneath the portrait of Beatrice, the instructions for finding the elder Ushiromiya's vast treasure of gold. But each line of the inscription calls for more death, more blood...and the revival of the witch Beatrice herself... Will any remain alive to see the end of this mystery?

The trial begins. With Erika as her prosecutor, Natsuhi stands accused of murdering six members of her family and staff. As red and blue truths conflict and collide, Be-atrice must defend Natsuhi from her charges, hoping to prove instead that she--Beatrice the Golden Witch--is responsible for these crimes. But when the wicked witches of certainty and miracles take over the game board, can Battler wrest control from them?!

Each year, the Ushiromiya family gathers at the secluded mansion of its patriarch, the elderly Kinzo. It has been six years since Battler joined his cousins at the annual event, but their happy reunion is overshadowed by worsening weather and an eerie premonition from his youngest cousin-not to mention their parents' feud over the inheritance. Battler doesn't hold much stock in dark omens, nor does he believe the tales of the witch rumored to have given his grandfather a fortune in gold...and who walks the halls of the mansion to this day... But when the eighteen family members and servants are trapped on the island by the raging typhoon, the grisly events that follow leave Battler shaken to his core. Is one of his relatives desperate enough to kill for the family fortune? Or is this the work of the Golden Witch?

Battler assumes control of the sixth game, wielding his new Golden Truth as he parries the logical blows of the detective-and-witch, Erika Furudo. For Battler, what began as a contest over the existence of magic has become a fight to revive the fiery, vibrant Beatrice of his early clashes on the game board. The logical loops and rules of the game were already complex; now, as the game master, Battler must quickly learn how to shape the events to his and Beatrice's ultimate ends without getting locked in a closed room by Erika, the witch of truth!

With the six sacrifices of the first night claimed, Beatrice, the Golden Witch, turns her attention to selecting the sacrifices for the second night: the "Two Who Are Close." As the corpses begin to pile up, Battler struggles to disprove that the deaths can only be explained by the existence of magic, and the crafty Beatrice is using every strategy in her playbook to trip him up. Logic and truth perform an acrobatic dance in which a single misstep could spell certain death. Can Battler defeat Beatrice in this match of wits and wills? Or will he find himself kneeling at the witch's feet?!

It's time once again for the annual family gathering on Rokkenjima! Ange Ushiromiya is just getting over a cold, but that won't dampen her excitement at seeing her cousins again! Granddad couldn't be more thrilled to see his beloved grandchildren and throws a special Halloween party where everyone gets lots of treats! By lunchtime on the first day, the aunts and uncles are chatting up a storm, and the cousins are eagerly planning the afternoon's fun. It's the very picture of a happy family-one that in no way resembles the bickering, bitter Ushiromiya clan! What is going on?!

Time holds little meaning for Beatrice the Millennial Witch. Replaying the events leading up to the Golden Banquet again and again only gives her more opportunity to play with her new favorite toy, Battler Ushiromiya. The boy's will to resist the witch remains strong as the curtain rises for a third time on the Ushiromiya family's annual reunion. But as Beatrice pulls more and more players into the game, the strain on Battler's defenses is evident. Do the other members of his family hold the key to solving the witch's riddle and sealing her defeat?!
