Yes, Haragami PC Edition requires at least 100GB of available memory space. This is because the size of the installation package for Harajin PC Edition is about 20GB, but you still need to reserve some space to store the game data after installation. And during the download and installation process, the installer and game files will be **** stored for a while, and the installer files will only be deleted after the installation is complete, so more than 100GB of space is needed during the installation process.
