[The pile of bricks and similar debris has mostly fallen towards the inside of the sushi bar, where it is covered in soot - and indeed, many of the bricks are charred to match. There's a bunch of blood here, but not only that... several pieces of bone are mixed in - shell-like pieces that could appear like a shoulder bone and collar bone if puzzled together. They're burnt as well, with the outside more white as ceramic under the soot and the inside more tan.]
