The fourth installment in "The Detective Kibukawa Ryosuke Case Tale" series!
Red leaves dance in the heart of Shirasagi, who was left behind this year.
The story of Sagishima Izuna, the assistant detective, and his unknown past.

【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】

The case begins with the protagonist, who has lost his memory, waking up in a mountain forest where autumn leaves are flourishing.

She is rescued by a high school girl who calls herself "Taihouin Izuna", and is informed that he is in Momoshiro Village, a small village deep in the mountains of A Prefecture.

Who am I? Why did I come to this remote village? Why did I lose my memory?

As the protagonist unravels her memories together with Izuna, she becomes embroiled in an inheritance problem that swirls around the village....

This is a sad and painful case that leads her to become a detective.

*This work can be enjoyed before and after "Shirasagi ni Kurenai no Hane" (The Egret and the Red Feather).

【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.
