【Game System】
This is a mystery adventure game in which the player solves a series of difficult cases that occur in a fictional town called Marihama City in K Prefecture.
The player controls the main character in the scenario and solves the mystery by selecting commands in the conversation and deduction parts, and by gathering information and evidence that will serve as clues to solve the case.
The story progresses by command selection, so even beginners can easily play the game.
【Story】
A request came in to the Kibukawa Detective Agency.
The request came from an old acquaintance of Kibukawa, Daidoji Genzo, who wanted the protection of the Daidoji's treasure, "Tokoyo no Watashi", which had received a notice of theft.
Masao Ikurumi and Izuna Sagishima go to the site in Kibukawa's absence.
There, they become involved in a strange incident involving a hidden treasure.
They were investigating the hidden treasure at the Daidoji house.
Then, they find a strange corpse on a snow-covered road on the property.
What is the end of the story played by the dead body that no one knows...?
【Character】
◆Ryosuke Kibukawa (癸生川凌介)
The director of the Kibukawa Detective Agency and a detective himself.
However, he is quite an eccentric character, often causing trouble and confusion for those around him, though he doesn't seem to care about it at all.
It’s completely unclear what he's thinking, but he has led the resolution of numerous difficult cases up to now.
◆Izuna Sagishima (白鷺洲 伊綱)
A detective assistant at the Kibukawa Detective Agency.
Though she is an assistant, she is exceptionally capable, and could likely solve most cases on her own.
However, like her superior, she is unaware of her own quirks. She has a rather eccentric personality, sometimes clumsy, but also sharp enough to make one wonder if it's all part of a calculated act.
◆Masao Ikurumi (生王 正生)
A game scenario writer.
Recently, he has mostly been working on mobile app projects, including turning cases involving the Kibukawa Detective Agency into adventure games for public release.
Because of this "favor," he can never quite stand up to Kibukawa or Izuna, and is always flattered by them, which leads to him being made to work for free.
