The goal of these fights is to strip your enemies of their clothing. You have to perform a certain amount of combos and attacks aiming for certain articles of clothing your enemies are wearing. The weaker the clothing, the easier it will be for your character to strip them away.
Partners
When entering battles, the main character will be partnered up with one of two other characters: Touko Sagisaka or Shizuku Tokikaze. While you are fighting with enemies, your partner will be fending off a few of their own. At the top left of the screen, you will see a picture of your partner along with a gauge. Every hit you land on an enemy fills up this gauge. When the gauge fills up, you and your partner will be able to perform a powerful combo attack on an enemy that may end up with both of you stripping away all of the clothing of that enemy.
Stamina
At the bottom left are three gauges that represent the stamina of your articles of clothing: headwear, tops, and bottoms. You can replenish the health of these items during battle. They only appear when your character is in fighting mode, though.
Leveling Up
The more your character fights, the more your character levels up their clothes-stripping skills. They would be able to weaken the clothes of the vampires more easily as well as strip them more easily.
Battle Results
After your character and partner wins the battle, they can obtain the articles of clothing that their enemies wore. The shops aren't the only place your characters can obtain merchandise. Your characters also receive money to buy merchandise from the stores available.
