According to the official web diary, the President of ufotable Kondo Hikaru said the Blu-ray box sets of Kara no Kyoukai have sold out in the US. Before the release, one of the local distributers asserted that the more than $300 price was ridiculously high in the US and that nobody would purchase it. Kondo didn’t disclose how many sets have been sold, but he had a toast with the local buyers, who were also astonished at the sales. Kondo is visiting San Francisco to attend the screening of Kara no Kyoukai.
