The adventure game with strong puzzle elements sees players visiting heroines’ rooms in search of the “Nandala Gandala” book in 3D environments (with 3D character models made by Flight Unit). While doing this, you can select a point in the room to try and trigger a prank. If your prank is successful and you level up, Chiranosuke will appear and the story will advance.
When you get a peek at the heroines’ delicates, your “Outbreak Gauge” will increase, and if it reaches its max, you’ll destroy the entire human race. The story will follow parts and mysteries not seen in the anime, as well as have different endings. The game adds 10 episodes over the 12-episode anime. And the second half of the game will have entirely different mechanisms than the first half.
