Hakui is from the sixth generation of hololive, and is the self-proclaimed “brains of the operation” in the Secret Society holoX.
The game will be the fourth collaboration between hololive and Entergram. Previous games include Okayunyumu! and its sequel Okayunyumu! R with VTuber Nekomata Okayu, and AQUARIUM with now-former VTuber Minato Aqua.
