【Story】

By the middle of December, during the end-of-year cleaning at the Kibukawa Detective Agency, Izuna Sagishima and Masao Ikurumi discovered a hidden document in the office.

It was a record of a tragic event left behind by the former detective assistant, Ryoji Sagishima, who had once worked at the agency.

What was he trying to tell us, and what did he want to leave behind...?

【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.
