Yuusha Shisu

Yuusha Shisu (Hero Must Die) is Japanese role-playing game about a typical hero of a fantasy RPG that dies right after killing the final boss in his adventure, The Demon King. However, even with the Demon King defeated, the world still faces many problems so god gives the hero five more days of life in order to fix all the unresolved issues in the planet he just saved. Yuusha Shisu is a reimagining of a mobile phone RPG of the same name that was originally released by G-Mode in 2007. The remake features new artwork drawn by Tetsu Kurosawa, a redone polygonal presentation, new story content, and an arranged soundtrack by Kenji Ito.
