About the Game

"The Detective Kibukawa Ryosuke Case Tale" Series - Part 1!
Play and Die Online RPG.
Uncover the secret hidden in the game, and its truth.

【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.

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 selecting commands, so even game beginners can easily play the game.

【Story】

This case begins with an investigation into a rumor of an online game that will kill players if play it.

At first it seems like a simple investigation, but one problem after another arises, and the actual case...

Please enjoy the many mysteries woven by complex human characters.

【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.
