23/7 Twenty Three Seven is mobile RPG and the brainchild of a collaboration between pachinko company Fujishoji and Kadokawa. The game has in fact been worked on for two years and will finally be out this coming winter 2017, having made its debut at the Tokyo Game Show. An Android beta will be opened on 7 December 2017 with 3,000 spots available. Interested players can go the official site and submit their email address for a chance to become a beta tester.

The backstory is rather cryptic at this point in time, but in this world, the number nine disappeared from all clocks for days for seemingly no apparent reason. That very day had only 23 hours, although nobody noticed. Within each number of the clock lies 12 dimensions, each with their very own guardian, also known as Clockers, that is able to control time. Ordinary Japanese high school boy Hikari is suddenly caught up in a fight between the Clockers.

The developers enlisted notable illustrators, Nagi of Kaku-San-Sei Million Arthur and lack of Fate/Grand Order fame to work on the designers. Meanwhile, voice actor siblings Uchida Maaya and Uchida Yuuma will voice the protagonists.
