The first single, Rashazakura, was originally scheduled to be released on May 5th, but the date was pushed back to September 9th so that Isshi could focus on Kagrra’s indies ‘Best Of’ album. Incidentally, the staff members managing Isshi’s shop started shipping orders of Rashazakura before this release date.
In late July of 2011, it was announced that Isshi had fallen into eternal sleep inside his own home on July 18th. His age was 32 years.
Despite Isshi’s passing, support members of shiki∞project continued work on the concept album Isshi was working on before he died. It is called 紅葉 (kureha), and set to be released on December 7th, in honour of Isshi’s birthday. In addition to Kureha, all prior goods made by Isshi will be sold on shiki shop for as long as they are available.
