Midoumaru’s grand estate is plagued by a series of bizarre, almost spiteful disturbances. Having just resolved to walk the path of a detective, Kibukawa volunteers to investigate. But as his inquiry unfolds, a far more sinister truth emerges—one murder after another begins to occur. Can young Kibukawa uncover the truth behind the chilling incidents haunting the Midomaru estate… before it’s too late? 【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.
