Bern appears with the meta frame, saying that even if the crime of the 5th hasn't happened, there is a mystery to be solved. Battler is silent, then says he challenged it several times, but.... Bern finishes the thought for him, saying he stopped thinking and threw it out. He can't respond. He has no idea how to solve it.
Bern tells him to be prepared...because she will solve it. He asks how. LD appears, asking if Bern has solved it. She says it is as you would expect from the witch of miracles. "No matter how difficult the mystery, if a chance of solving it exists it will be solved. LD asks how many years and tries it took to solve. Bern chides her, and says is only took hunting a few hundred kakera, or something like that. LD laughs, and says she is frightening. She seems to wonder what Bern will do with the answer? Bern tells her to be relieved. She...something related to players?
Then, LD laughs, and says something to Battler about not getting drunk, and they disappear. They seem to be in the sea of kakera. Battler groans, it is painful or something. Bern chides him, saying that he was even told not to get drunk. LD tells him to invent it himself if he wants gravity. To imagine firm ground is beneath his feet. The two witches are standing normally, only Battler is floating. Watching their calm, he calms himself, and stands.
LD says "Skillful". Then asks who he is? He says he is Ushiromiya Battler. LD says some stuff about feeling, form, and other stuff, then mentions the sea of kakera and seaweed. Battler doesn't know what she means, which makes two of us. The more he settles down, the more stable his body seems to be. The feeling like floating is lost slowly. Bern appears, and says it begins; the Kakera to solve the mystery of the inscription is spun.
She spreads her hands, and the kakera warp around them. They rush across connected Kakera 'constellation' as ridiculous speed. A particular Kakera begins to shine and orbit Bern like a sun, and when it passes near Battler, there are flashes of memory. Battler considers maybe the kakera is memory? Or something? LD denies it, saying Kakera are worlds, but maybe it feels like memory to him.
Bern comes over. She starts. First, she indicates a kakera. One of the kakera from the solar system she made comes over to them, shining until everything is pure white. We see Young-Eva, solving the puzzle.
She mentions that the beloved hometown isn't a trick, it represents the past childhood Kinzo longs for? I think.
Battler appears, saying he remembers, this is the thoughts from the third game before Eva solved the inscription. Bern says it is the idea from which she span the correct answer. In other words, this reasoning is not wrong. Battler seems to think this isn't much help. Bern shows him something else. It is Eva reasoning that perhaps the hometown he longs for is not Odawara. Rosa also appears. In the story of Kinzo's childhood, he had a happy boyhood. They exit the scene, agreeing that it isn't Odawara, I think. LD taunts them. I think she is saying they are missing a hint? Battler tries to puzzle it out, but can't. Bern says something, I think she is having trouble too. Battler comments that she seemed so certain, "If it can be solved it will be solved" and all. She says something, and says the answer must be squeezed? Young Eva scene again, she is talking about maybe the river isn't one in which fish can swim. She ponders river...river...river. Association with "Genealogical tree" isn't bad.
Back out of the kakera. The river that flows in the hometown, but it isn't a real river. Eva figured out an interpretation of river for her answer. Battler agrees, but asks what is is, then. Bern tells him to think, "River that runs through a hometown". It is not a river where water flows. But something like a river. Battler looks frustrated, and can't come up with one. Bern says, "River that runs through nostalgic hometown". She says they round down the [ayu] though since Eva did, I think?
Another kakera scene, Eva and Rosa facing off. "I worried too much because of "Ayu River". But the ayu part was meaningless/unnecessary. But it was a splendid hint? Back outside, Battler struggles with what ayu means, if the river is not a river, neither are the fish that swim in it. LD taunts them again. Bern suggests the hint isn't ayu itself, but something it makes you think about/related to it/word play? Battler is silent. Eva went to the library and found something in a book that verified some bit of her thinking.
In other words, she made an assumption, and the book confirmed it. The hypothesis is verifiable according to a book? And understanding the true colors of the ayu makes the mystery easy to solve. Battler agrees that is a good idea. He comments that she couldn't understand the three lines at first.
Cut to another kakera scene. Eva in the library, trying to figure out what the hometown is. After a moment of puzzling, she has an epiphany based on what she already figured out. Battler reasons then, if you know what the river and ayu are, the rest can be understood immediately. Bern agrees, but does not know what Eva found in the book. Battler curses.
Another scene. Eva is saying something about not six characters. Can't fit it with six characters? Young Eva chides her, telling her to devise a method that can read it by six characters, to look it up if she has to. There is a string of her counting, and saying random words, ending with key. Back outside, Bern says that is where she found the key to El Dorado(Golden Land?). Battler says the key is some word or figure of six characters. Bern agrees. He tries to puzzle it out. He quotes the first sacrifice from the puzzle, and seems to realize something about it.
Another kakera, Kyrie. "This key indicates six specific people". She says it doesn't mean a literal sacrifice. Perhaps the answer is an anagram. Klauss questions this. Back out of the kakera, Battler realizes Kyrie was on the right track. More Kyrie. She is figuring out wordplay meanings in the puzzle's sacrifices.
He reasons, in other words, from the six characters from the first sacrfice are the keys that are "Kill." Meaning to do something with the remaining characters? Bern agrees, but notes that Kyrie nor she knew where to kill the characters from. If that is what you do in the evening though...Battler reasons the character string must exist already?
"However, there are only four characters in "Slowness of first". Is it other pronunciations? Maybe in English, "<1st-night>"(in english)?
Moment of silence, and meta scene ends.
Erika is saying "Good". She is praising Battler's idea for a solution, the one he just suggested in the meta world. Only as far as removing six characters, though. Kyrie also mentions she had thought of something similar.
Rudolph says they still don't what which characters to pull from what. Eva says..something? Rosa suggests it being by Kinzo, it might involve English.
Erika brings up the second sacrifice. With the same reasoning, it would mean characters that remain after pulling out six characters? George and Battler try to figure it out. Battler and co. reason with a string of numbers. If the answer has you remove everything but 2, 4, and 5, 4 and 5 are the "Two who are close". Erika praises Battler. They try to work out the third twilight.
George and Battler reason it must be a anagram/character play. Erika agrees. Also, Battler and Erika reason that they start with 11 or 13 characters, based on the meanings they've come up with for the twilights. Erika praises Battler. He seems embarrassed.
Change over to meta world.
Battler is not amused. He is annoyed with game-Battler. Bern apologizes, saying she played with him because he was absent? Or something. LD appears and laughs too, saying the piece him is way smarter when Bern controls it, as she did until October 5th. The game they have been seeing is only a replay of the part he missed, I think he says.
He wonders why Bern is so insistent on demystifying the epitaph, I think. And what the meaning of it is. LD had an interest in it too, he notes, thinking back. He notes that the reasoning of Bern and Erika that it is to determine the successor is good. However...that would have been when grandfather was alive. What about the challenge letter that appeared from Beatrice so many times, that urged them to solve it and threatened death if they didn't?
He says that it is in a word, hope. But the relatives usually don't take it seriously. He tries to figure out why Beatrice helps his grandfather's dying wish to succeed, I think? He wonders if there were orders to that effect, for what to do when he dies. He wonders who is the one who names themselves Beatrice, manager of 10t of gold, and self-proclaimed alchemist. Who holds the gold, waiting to entrust it to someone who can solve the inscription. And if they human doesn't do it in time, game over?
Eva, who solved the mystery, is the game's only survivor. Automatically succeeding as head of family and everything else. She is the only example of returning alive from the island.
A moment of silent thought...
The starting point of Beatrice may be loyalty to grandfather, or...
Exterminate if you cannot solve the inscription. Loyalty...devotion to a frightening instruction of the late master. He thinks more, and chides himself to not stop thinking. More thinking...What is Beatrice's reason for challenging them with such a difficult inscription? The miracle for the person who solves it is apparently known. But what is the value of the miracle for Beato? He doesn't know.
Back in the game world, they continue to try to work out the epitaph. Battler tries various ideas, but they make no progress. Maria yawns in a over-the-top fashion. Others yawn as well. Jessica stand up, and says she is going upstairs with Maria, to watch television. George agrees to go too. He suggests cards. Maria is instantly awake and energetic. The adults are also tired from traveling. George asks Erika if she wants to go with them too, to play cards.
She agrees, adding that she is enjoying her stay, and has already almost forgotten the accident that brought her here. Rudolph likes her vigor, and Eva laughs, and thanks her for helping to advance their reasoning on the epitaph. IF they find the gold, she can have a share. Hideyoshi laughs. Erika smiles and says not to worry about it, it is only the mystery she cares about. She excuses herself. Battler says goodnight. Rosa asks if he isn't going to go upstairs too. Battler says he wants to think a little more. If he can just figure out the first string of characters. Everyone went upstairs, but Rosa. Kyrie offered to stay, but was told not she didn't have to.
Battler and Rosa puzzle over the epitaph some more. They pay particular attention to the 10th, and the village of gold. Battler continues to reason. Rosa says Battler and Erika are amazing. She says she is just too old to think in such ways, I think?
It is amazing how they figured out the six characters thing. She praises him and says she's not too smart, but he counters by saying she is smart too, to think of the significance of the 10th. They try to puzzle it out. She thinks that the fact they are traveling to the golden land has some significance throughout the puzzle.
They do some other reasoning, about the time traveled and stuff, but don't seem to get anywhere.
Battler continues thinking about the mystery for a long time, even as he cleans up after himself.
Battler runs into Erika messing with a key by a door after he leaves Rosa. He is surprised to see her on the first floor, since her room is on the second. She says she is looking for something. Battler is puzzled. She turns the key and opens the door. The room is dusty; its a library.
Battler asks what she is looking for in here. She says a book or 'material'. She wants to examine something. Battler asks if it is related to the inscription. He admires her lack of resignation, and asks if the 20 billion is why. He thinks to himself that he is the same way, not wanting to resign.
Erika says he must be kidding; she only cares about the mystery. She wants to find the gold to prove her reasoning is correct. She comments that if one of the others find it, it might just disappear. Battler mentally agrees that her impression isn't wrong.
Erika begins to look for the book, moving through the bookshelves. There is some reasoning about the puzzle, lots of JP wordplay I couldn't get, as she looks for a book. He mentions Rosa's idea about ten days, and Erika agrees. She wants to check a book, to turn a guess into conviction. He asks what she is looking for, as she finds it and blows dust of. It is an atlas.
