SHUTEN ORDER begins with an apocalyptic countdown and a murder. Its protagonist wakes without memories to learn they are the murdered Founder of the Shuten Order, revived with only four days to identify and kill their killer. Under the alias Rei, they investigate five ministers in a city shaped by the Order’s turmoil. The urgent deadline gives the mystery a clear structure: pursuing one suspect means making choices about which leads to follow and what sacrifices the search for truth may demand.
The investigation changes genre from route to route. In the Ministry of Justice, players interview people, examine crime scenes, scrutinize statements and objects with the “Snapping” feature, then assemble evidence in case-analysis meetings. The Security route instead pairs top-down 3D puzzles with flight from a killer, while the Science route shifts among characters whose actions can affect one another’s fates. Education turns suspect-hunting into a romance adventure, and Health presents a locked-room escape challenge built around dangerous trials and puzzles.
That mix makes SHUTEN ORDER more than a single-form detective story: its five suspect-linked routes alter both the narrative and the gameplay, ranging from investigation and visual-novel storytelling to stealth horror, romance, and escape-room puzzles.
