You play as Ataru Sagumoto, a travel-loving private investigator who stumbles upon a quiet village—only to be caught in the middle of a murder.

Your mission is to gather key testimony keywords by speaking with villagers and collect physical evidence items scattered around the scene.

Once you’ve gathered enough clues, you can convene the villagers, confront the suspect using the keywords, and present evidence to force a confession.
