For the first time in the series, the game will have Buddy characters that participate in battles to help the player, in contrast to Supporter characters that only worked behind the scenes in past games. There are situations where tanks are placed on the battlefield, which you can enter and control tanks to annihilate monsters. When the girls are attacked from monsters, their clothes will gradually be destroyed as they receive damage. The more the clothes are destroyed, the more damage is received for same attacks.
The key feature in the series, 'Interrogation Training', is a mode where the player can tickle or slightly annoy the girls by simulating a situation in which they are caught by an enemy. You can use various interrogation items like water guns and condensed milk. The character's mood changes and gives different response depending on the item used in the interrogation.
