To be honest if it's somehow similar to the epitaph, I find it likely that we have to scramble the numbers in a way to decipher a logical solution somehow. But of course that complicates things further to figure it out.
I believe they are probably letters and not a date. The 0715 date is only addressed to Battler to let him know he is the one the message is addressed. I agree though, at the moment it's just there to perplex us readers.

Eh i never went that far, and it's not even a theory i devised. All i know is that most people speculate it's a bank account number. I'll have to see the whole episode4 to determine if this idea is really grounded or not.

About the idea that it's a date. 0715 being Battler's birthday might just be a coincidence. Ryukishi likes to give false hints especially if a mystery element has just being introduced.

I don't think they form letters anyway. This has been speculated for long in many strange ways and nothing substantial has been found.

I've also tried so see if something happened on 15 July 1129 but i didn't find anything. I wondered if this could be the supposed birth date of Beatrice. But then it would be a little less than a thousand years and the "real" Beatrice loved by Dante lived around 1300 AD.

In conclusion I don't think it's possible to reach any logic conclusion. This is Ryukishi teasing us, he knows we can't possibly understand anything from that. That's what i believe.

So you reckon Beato (or the Mastermind whoever that be) bribed someone in ep3 and the number is a bankaccountnumber with money is the compensation (and the sign on the wall is the number to access it)?
Well I dunno, but it seems real far-fetched for me (no offense). And the coincidence that it begins the with same number as Battler's birthday has astronomical chances. Unless she deliberately choose to open a bankaccount starting with 0715, but for what reason? Even if it's a completely random number no one is going to find out the original purpose, there's no need to make it look like it's related to Battler. And I don't see why do they have to paint it under them magiccircle, why not a small note or something.

I'm fairly sure it's addressed to Battler, but I have no clue about the second half. It's also possible the 0715 is a sign to Battler, but the "code" is longer like 151129 or 7151129 etc. So whoever wrote it has to be familiar with him to a certain degree, and knows he is a clever lad to find out the code.
If I were to take a guess what's that, I'd say they are the letters somehow related to the killer/accomplice/accomplices and it's left by some of the victims who lived long enough to paint it there. Of course I didn't researched it yet, if it's feasible with characters/victims and such. It's just from the top of my head, and it's only my guess. But whoever wrote it definitely wanted people to find it.

However it might be too obvious to be the killer's name I don't really know. It might be some codeword again after figuring it out, which has no revelance to someone who decipher it finally, but Battler could guess the killer/accomplice/accomplices from that word.

Buona sera.
I went through them threads but I haven't found your theory about it yet. I ask it here instead (it's not important or anything, I'm just curious what do you think about it).
What's your take on Umineko's 07151129 clue? Do you think it's a biblical reference addressed to Battler or you reckon it's something else?

Ps: didn't wanted to revive that debate in those threads again, hence the Visitor Message.

Oh yeah now that you mention it, even when it's finally going to be out, we still have to wait another 2 weeks to understand it with subs. Damn, those are the times I wish they could have taught me japanese in the school instead of silly german I don't even use anymore. I agree with you on ep1 (not enough Ni-pah for me to consider it enough fanservicish ), however I loved ep2 and it restored my faith in higurashi. I definitely anticipate the rest of the series myself (anyway feel free to disagree with / comment on my theories in ep2 thread ).
Yeah CG was silly really, I stopped taking it seriously after one of the first episodes. Nevertheless, it is a textbook example of how to make something ridiculously popular (idolized as you said too), despite having a really inconsistent story. The execution and the cliffhangers kept everyone interested, even though everyone knew it is a shitty plot.
Anyway check out the first one or two episodes of Sengoku Basara if you haven't done so yet, it's really worth it for the laugh in my opinion.

I agree Eden of the East is actually the best this season so far (no wonder the creators almost all the same as in Ghost in the Shell). Too bad it's only one cour, but hopefully the story gonna be finished in such a way, where a second season might be made.
I dropped K-on after this new episode, because I'm disappointed in it. I didn't expected it to be Lucky Star 2.0. I would have preferred it, if it actually involves the music aspect a bit more, because currently it's entirely not focused on it, and just tries to capture everyone by moe overdose. That's not my thing unfortunately. It's a shame, I was anticipating that series, being Kyoto Animation and their Haruhi concert.
For some reason 07 ghost reminds me too much of the gay side of Code geass, and it seems it's not going to focus on the things I liked in CG (the unintentedly hilarious, badly written plot and it's execution), so I dropped it after halfway through in ep1.
Well I can't really grasp Valkyria so far though. It's enjoyable, but there are several inconsistencies in the execution I dislike (not realistic etc), however the viewer has to take it seriously. I'm still following, but depending on the story I might drop it later. I'm not familiar with the game though.

I'm following Asura Cryin' too for now, but I'm not impressed with it so far. It explains so little that I have to stop it every once in a while to ponder, wtf is that supposed to mean, and it tries to involve too many genres. It's quite possible the 4. episode going to be the last I see, unless things drastically change in it.
So far I'm positively impressed with the Requiem of the phantom, because despite being made by Beetrain, it's actually faithful so far to the game, which I played few years ago. Some scenarios in it are quite enjoyable, and I definitely gonna follow it, until it's clear which route the anime is going to animate.
So far I'm following Tears to Tiara too, but depending on the later episodes I might drop it too. I know the game's story, and if they animate it in such a way I'm not gonna like, then I'm not gonna follow it just for the already familiar story.
I'm watching the new FMA too, because I'm curious about the manga's plot, and I've found the the first series pretty good few years ago, apart from the last twist involving Nazi Germany and their robot army in 1933 .
I just noticed you might don't know Sengoku Basara! I recommend watching at least the first episode. It is hilarious. It's like someone animated my dreams of history when I was a kid, with a high budget. I'm laughing on it so much. Of course it's not to be taken seriously, but it's such a great manly show, my beard grows out full length, everytime I watch an episode .
Of course I'm patiently waiting on the Higurashi OVAs, it's a shame they come out so rare.

Have you tried these? If yes, what are your impressions about this shows?
ps: damn, why is it not possible to put spoiler tags in visitor messages? :/

Which series you following by the way this season Jan-poo?

Bon Giorno than! Scusi per assuming it lol . Myself speak spanish, so if I really stretch myself, I can comprehend some very basic grasp in Italian though (provided I hear/read the similar words), but obviously other than swearing, I don't really know much how to answer it . Ciao amico!

Hey Jan-Poo! I'm just wondering which country are you from. I could see you speak french to a certain degree, but I'd find it surprising that I'm not disagreeing too much with a french . (truly no offense intended).

I also learned by myself, because I speak spanish I read a very very very complete mexican page with all the theory. I get the kanjis from this site: www.kanjiroushi.net I memorize them to disting them too. Im learning kanji as the noryoku system.
