The title, which has yet to be announced by Spike Chunsoft, is likely a localization of Steins;Gate: Hiyoku Renri no Darling, which was first released for Xbox 360 in June 2011 in Japan. It was later ported to PSP in April 2012, PlayStation 3 in May 2012, PS Vita in March 2013, and iOS in October 2013. The Steins;Gate: Divergencies Assort collection released for Switch in March 2019 in Japan also included the title. An English version of the game was never released.

In this world, a new gadget had been created but the group is facing some troubles. They can’t afford to pay the electricity bill due to running too many experiments. Let’s see what this new gadget can do for us…
The concept for this game is a love comedy with some sweet romance scenes and where 99 percent of the world is science but one percent is composed of… fantasies?!
