The wealthy merchant Kotaro Kageya was poisoned. His final testament: only a few cryptic Tarot cards.

Distrust and suspicion swirl around the Kageyas over a vast fortune. Detective Ryunosuke Todo enters the "Kohakukan" mansion alone for a secret investigation, only for more murders to occur. What did Kageya entrust to those cards? Who is the killer...?

A classic mystery set against the brilliant stage of Taisho Roman.

This is an adventure game released in Japan by Riverhill Soft in 1988. It is the first "Ryunosuke Todo Detective Diary." Players become detective Ryunosuke Todo to solve a murder case at the "Kohakukan" mansion.

The core of this detective mystery lies in navigating a complex web of characters and relationships to uncover vital clues. Set in a sepia-toned world of Taisho-era romance, you must use your wits to solve this increasingly difficult case. Who is the true killer behind these escalating murders? And what is their dark motive?
