Grampa has barely announced he'd kill everyone in the room when he suddenly summons three Siesta sisters. They immediately snipe Natsuhi, Hideyoshi, Eva, Rosa, Rudolf and Genji. The quota for the first set of sacrifices is reached, so the others will just be kept as hostages. He summons another demon called Gaap (whose costume design is Stripperific Gone Horribly Wrong), who teleports Krauss, Kyrie, Shannon, Kanon & Dr Nanjo in some sort of cell (that's her power). Gohda & Kumasawa manage to escape and reach the guesthouse, where they warn the grandchildren about what happened.
In the cell, Kyrie finds a working phone (!) and manages to call the grandchildren in the guesthouse. Everybody compares their notes, and the hostages decide to do nothing for now while advocating the young ones to hole themselves up in the guesthouse.
Grampa shows up soon after, accompanied by his cronies (Gaap, Ronove and Virgilia). He gloats that the phone was on purpose, so that the grandchildren could be given instructions for their tests. First, they have to lock up Gohda and Kumasawa in the garden shed (which they do, but leaving the key inside : they can't go out, but nobody can attack them either). Jessica goes first to her own room in the mansion, while George goes to the rose garden. Each of them is handed a Sadistic Choice (by resp. Ronove & Gaap) : they have to sacrifice one of the following three - (1) themselves, (2) their loved one (resp. Kanon & Shannon) or (3) everyone else. For the record, Jessica choses herself (she would not be able to stand becoming the woman who'd have done any of the other choices) and George choses everyone else (he was prepared to fight his whole family for Shanon anyway).
Not that it matters much, since they both Take a Third Option (well, fourth... or even fifth, since "chosing nothing, and everyone dying" is acknowledged as a valid option). Jessica assaults Ronove with brass knuckles that are surprising effective, while George declares that "everyone else" should start with Gaap, and immediately demonstrates his knowledge of karate, jiu-jitsu and capoeira.
Those fight scenes are epic, but alas Gaap manages to subvert both of Jessica and George's killing blows by teleporting them next to each other. Ouch. Somehow, Jessica survives long enough to give a depressing phone call to Battler.
Meanwhile, the hostages have been left alone, and Kanon choses this moment to reveal that he's got psychic blades that can go through bar cells in no time. Time to escape ! Virgilia sends tons of goat servants after them, but they're too big to go through the little gaps in the bars our heroes have gone through. She readies the Siesta sisters, but Shannon manages to BSOD them through her long-distance shields (er, what ?). But just as they say Nothing Can Stop Us Now!, our heroes are stopped by Virgilia and a super-goat. Time for a boxing match between it and Krauss !
What has happened to Virgilia ? I know that everything I liked about her in Episode 3 was a lie, but here she's become a stupid James Bond villain with a full-scale Idiot Ball. She's spouting bad guy clichés like "I Lied"... and there's even a counter at the bottom right of the screen for each element of the Cliché Storm ! For some reason, this powers up Krauss's boxing ability. Combined with some Gretzky Has the Ball-style nonsense that sounds nothing like real boxing, this allows Krauss to overpower the super-goat, and make it land on Virgilia. So now our heroes can escape !
But they've barely reached the garden when the Siesta sisters reboot themselves, and take aim. Kanon, Shannon and Dr Nanjo are shot down immediately. Krauss is killed at the door of the mansion. Kyrie manages to reach some random room and lock herself inside... but she can sense the Siesta sisters trying to reach her through the keyhole. She uses her last moments to call Battler and narrate him everything that happened to her group. And then she stops talking.
Battler has barely hung up and started to go down the stairs when the phone rings again. Maria receives the instructions for her own test... and then passes the phone to Battler before going. It's "Beatrice" ! Battler is to meet her at the mansion's entrance !
Battler, using his last remnants of Genre Savvy, tries to gather the help of Gohda and Kumasawa... But as he looks from the window of the garden shed, he sees them both hanging from ropes, looking very dead indeed...
"Beatrice" is waiting for Battler near the mansion's door... but from a balcony on the second story. She foregoes the Sadistic Choice test (since Battler has no obvious loved one, it would be pointless ; he jokes he should put Beatrice's name on the second choice), and instead requests him to repent for what he did six years ago. Battler retorts that his dispute with his father has nothing to do with her, and that they resolved it at Asumu's funeral anyway (with Rudolf apologizing profusely). But "Beatrice" is talking about something else (and it doesn't have anything to do with the two of them, since she didn't exist back then). Battler has no clue what she's talking about, which infuriates her. She leaves.
In his study, Grampa is celebrating Maria passing her test with success. Somehow, this annoys "Beatrice" even further, and she burns him down without warning. WTF ?
The scene switches to the room where Beatrice and Battler are playing there game... and Beato has a new strategy. First, she removes anyone possible interferer from the room (this includes Lambdadelta and Bernkastel, but also ANGE/Gretel). Then she announces that she thought her game was with Grampa's grandchild... and uses the red text in a tricky way to prove that Battler is not Asumu's son. Having an existential crisis, he dissolves into nothingness.
Meanwhile, in the Future…, Ange has finally reached Rokkenjima, unboarding on the secret mansion's side. In full Idiot Ball mode, she leaves Amakusa on the boat, and goes exploring. Of course, she's easily caught by Kasumi and half a dozen henchmen. But this time around, she manages to kill all of them by summoning all seven knife-girls (!). Then she finds herself ready to help Battler...
Back to chessroom, ANGE/Gretel manages to come back, and summon back Battler's spirit to the board. She points out the obvious flaw in Beato's attack : Battler not being Asumu's son does not prevent him from being Grampa's grandson. Which he is.
Battler is still shaken by this attack, so ANGE/Gretel uses her ultimate card : she reveals that she is indeed his sister Ange, from a future where he never came back. This shakes him up out of his funk. But then ANGE/Gretel has to face the consequences of her action : not revealing her identity to Battler was the one condition she had to subscribe to in order to attend the game. So she dies horribly.
All this has completely reinvigorated Battler. He's ready to fight Beatrice on her game. Bring it on !
It's now midnight on the first day...
Next part : the two epilogues, and my comments on the episode and the whole series.
