Description: Use your character's abilities to take on enemies mutated by dangerous substances! In order to investigate the dangerous substances that have flooded the neighborhood, the girls run through barrages and enemy status ailments. You can use the points you collect during the item shop investigation to power up your character and acquire useful items. There are backup items that can restore the state you were in when you acquired it even if the game is over, and "high-stakes" items that can fully recover even if you are in a pinch.
