Think I get that last bit, based on the next part. LD is trolling, asking whether Kinzo is dead now, or if magic is real to revive him, or what. Doesn't actually seem like a strong trap, but Super-paper is kinda dumb, I guess. Anyways, she tosses out her challenge starts witch laughing.
Battler looks at her kinda angry, and tells her not to do a crappy imitation of Beato, because it is unpleasant. She trolls him more, mentioning (I think) possible dumb explanations, such as group delusion or "Six Island Syndrome", or shiny butterflies that only live on one island. The weird explanations continue. I'll quote so you can share in the bad translation glory
" such things as the act of medicine [purupurupikopuyo] of not yet known to show the group delusion that The Secret Adversary 'Mountain dog' of the mystery made. "
See what I endure for you people? Anyways...
Battler tells her to shut up and be quiet.
Red text: The grandfather-sama is already dead.
I *think* Battler said it.
He continues, saying the death was just concealed by Natsuhi lying and conspiracy, to which LD responds by asking if lying revives the dead. "So it wasn't Natsuhi's magic?" I think she says after that, de-gibberishing it. Battler says "This world is the world before it peeps at the cathode-ray tube. The world of [nekohako] before it opens."
He says that if its a lie, it doesn't matter what he is shown, as a dead man can be alive in a lie, if I'm reading this right.
Bern applauds him, saying Bravo, and says something about him and Beato. Battler gets mad and tells her to not bother him, and that she should shut up too.
LD calls his attention back to her, saying that his explanation is great if its his word versus Natsuhi, but where does Kanon fit in. Battler looks at her bored, and says of course he'll agree with what his employers say. LD looks put out, and Bern tells her that its too bad, but Battler won't get caught by low-level childish tricks anymore.
LD says its just an appetizer. Either Bern or LD start rambling out various premeal things, until Battler tells them to shut up. He mentions something about advancing through the blue text. LD agrees, and he states his theory in blue that his grandfather being alive is just a fantasy cooked up by everyone that they agreed to believe, and since they share the fantasy they can respond to it together. No one can contradict it and break their delusion, because he is 'alone in his study'.
He talks about how Kinzo hadn't been met straightforwardly in the games, but people still claimed they had met him. The people who said they met him were sharing an agreed-upon delusion, which made him real to them.
He concludes this as his opening response. LD and Bern respond, talking about medicines and science and stuff, and "Knox Article 4 story". Battler asks what that is. Bern says the use of a unknown medicine or super-science object is prohibited. IE no cheating with almost-magic pills/devices/viruses. Bern laughs at him, saying he should give up if that kind of thing was part of his answer.
Battler is thrown off. Bern taunts him further, talking about how he fought Beato from the front, but that wasn't right. He didn't fight fantasy vs mystery, he fought at an angle. Ie Anti fantasy, vs fantastic but exists. He seems a bit put out, and I think admits the flaw in his fighting. Bern continues, saying their job is to destroy witches, interpreting it as a formal mystery, not something right on the border of fantasy. She points out things like his closed room solutions, I think. Then she mentions Knox Article 3.
"The existence of a secret passage is prohibited."
Because they make the game too easy/onesided, if I'm reading this right. She says he lost every time he went to overboard with such things. Then she cracks up all crazy again.
Battler just kind of rolls with it. He asks about the source of the articles. LD says they are something like rules designed for fighting and breaking witch fantasy, made by a Archbishop Knox and someone else (accidently clicked past the name >_>). LD chides Bern for bringing such troublesome weapons in.
Battler asks some agitated questions, which I couldn't quite understand, about the whole deal. Bern comments that LD takes charge of the witch side, "fantasy". She who fights against it, is "mystery." But he keeps up the denail of fantasy while barely exchanging anti-fantasies. He's like a politician. Cue more witch laughing.
Battler tells them to shut up, again.
Will continue this in a moment.
