Tōdō Ryūnosuke Tantei Nikki: Zakuro no Tenkyō - Kisshō Chūshūsai Renzoku Satsujin Jiken

The sixth entry in the 1920 series follows detective Ryūnosuke Tōdō as he embarks on a request from a previous acquaintance to help save his son from danger. This request takes him to the Hotel Granade, where he's drawn into a series of murders that he must investigate.

This is a menu-driven adventure game with a strong focus on the time period and the specific locale in which it takes place. As in previous games in the series, it's heavily focused on the physical locations it takes place in, and players will find themselves frequently moving throughout the hotel during their investigation.
