Yamiyo ni Sasayaku: Tantei Sagara Kyouichirou

A sequel to Tsuki wa Kirisaku, following detective Kyouichirou Sagara. A mystery is unfolding aboard a luxury ocean liner: female passengers are disappearing without a trace. Unlike a conventional visual novel, the game uses direct navigation commands — look around the environment, talk to NPCs, check inventory, examine the map, and use the cursor to investigate objects directly.
