This is a Switch port of the mobile port of the DS remaster of the first game in the Tantei Kibukawa Ryousuke Jiken-tan series.

Embraced by illusions, I put on a mask... A mysterious serial murder case intertwines with the virtual world and the real world.

In April 2003, 8 months after the first work in the series, "Masque Fantasy Incident," Masao Ikuo, the scenario writer for this game, received an invitation to the beta test for the new network game ``Misty Online.''

``Misty Online'' was Japan's first MMOADV, and it was an unprecedented game in which players and their friends solve incidents that occur in a world that closely resembles a real city.

A response from a player playing the role of a corpse who participated in a beta test with Izuna Sagishima of the Igawa Detective Agency and tried to solve a fictional murder case, butdied after falling from a height. Gone...

Reality and fantasy. present and past. The countless threads intertwined in a complex and mysterious manner create illusions that envelop people's hearts.
