Today I received
Kara no Kyoukai Blu-ray Disc Box:

The box is pretty big (aprox. 30cm x 30cm x 5cm) and is pretty similar to the novel's limited edition.

Inside there are the blu-ray discs and an artbook called
Visual Chronicle. Both have a velvet-like texture that is easily marked with fingerprints.

The seven chapters are each in a blu-ray disc, as well as the 8th Special Disc.
The
Visual Chronicle contains all the illustrations from each movie dvd covers, theatrical posters (each piece with the personal comment by
Takeuchi or
Sudou Tomonori, the main illustrators) as well as an interview with
Nasu,
Takeuchi and
Sakamoto Maaya.

Announcement posters for the theater screening.

The cover and the special postcard from the limited edition version of each movie.

A rather long interview between
Nasu,
Takeuchi and
Sakamoto (
Shiki voice actress).

Each movie theatrical poster.

And the covers for the regular dvd editions.
Each chapter is contained in a blu-ray disc, without any extra besides the manners commercial. It have subtitle options in Japanese and in English.
I'm not an expert in blu-ray quality image, upscales and stuff, but the movies have a pretty visible smudged effect in the border lines, something like a translucent black glow.
Shiki in the 3rd movie.
Azaka in the 6th movie.
Is not really visible in the pics because those are photos taken in front of the TV, but compared to the dvd releases, the image have a sharper look and crisp colors, but in the outlines of the characters seems like a saturation of the Photoshop sharpen filter. I don't know if this is an usual technique for anime not drawn originally in HQ, because that effect doesn't appear in the final chapter, clearly done with the blu-ray edition in mind.

The final chapter, called
Kara no Kyoukai, is featured in the special disc. This was the last chapter in the novel and is a 30 minutes talk between
Shiki and
Mikiya in a snowy road. Well, is mostly a monologue by
Shiki, explaining issues like the human personality and origin.

Despite being only
Shiki and
Mikiya talking for 30 minutes in the very same scenario, the quality is astonishing and really shines in BD.
In the same disc there's also included
Kara no Kyoukai Remix -Gate of seventh heaven-, a recap movie of the first 6 chapters that includes a single newly done scene. Each chapter uses the respective theme song as the background music, so is like an hour long video-clip.

This is the only new scene in Remix.
And the last extra is a special TV program that was aired to promote the seventh movie. Is mostly a recap of all the previous movies, but with short interviews to ufotable's crew.

I didn't re-watched all the movies yet, but it seems that are not retouched or edited, except for
the glaring mistake in the 7th movie:
To complete the set of dvd versions that I already own, I also purchased the dvd version of the last chapter.

It doesn't have any of the extras of the BD version, and after seeing it in high definition is hard to return to dvd quality...
