While 5pb. is already working on Chaos;Child—the latest in the science adventure series that includes Chaos;Head, Steins;Gate, and Robotics;Notes—they also have a visual novel in the works with a much more ridiculous title. See a teaser for their collaboration with developer La'cryma, Kadenz fermata//Akkord:fortissimo, below.
The characters featured in the teaser are Freya, Amaterasu, and Alicia, who are all part of a story that pits "Transcendent Theosophy" against "Mythological Creation." Kadenz fermata//Akkord:fortissimo is due out later this year.
