Part of a series of adaptations of Kyotaro Nishimura's suspense stories -one of Japan's most popular and prolific mystery authors-, the game follows an investigation set between Kyoto and Atami, resolved through dialogue, clues, and deductions in the style of detective visual novels. It's a product designed exclusively for Japanese readers familiar with the author, within a 'train and hot-spring resort mystery' subgenre very typical of that country's televised and literary crime fiction.
