You stumble upon a hidden cave behind the Hakurei Shrine, drawn by an otherworldly hum. The cave leads you to Makai, the demonic realm created and ruled by Shinki, a powerful and enigmatic deity. The realm is a breathtaking fusion of divine artistry and mechanical precision—floating gardens of crystalline flowers, clockwork spires, and rivers of liquid starlight stretch before you, all bathed in the glow of an artificial golden sky. What will happen when you encounter the God of Makai herself?
