The upcoming enhanced PS Vita and PSP re-release Toukiden: Kiwami will be available in a special Treasure Box when it launches in Japan.
The Toukiden: Kiwami Treasure Box will include a Tenkitsune toy plush, an art-book, a soundtrack CD and a selection of DLC costumes, all of which can be seen below. This package will be available for the PSP as well as the Vita. I guess the PSP is still alive and well in Japan.
Toukiden: Kiwami launches on August 28th.
