Dark White is a colossal monster resembling White Heart, and based on the monster of the same name in Megadimension Neptunia VII. It is first found in the 5* multiplayer mission "Dark White"
Dark White will mainly attack by slashing with the claws on her left hand, or the axe on her right. During some of her attacks, she will move away from the arena where you can't attack her during the motions. After a while, she will also attack with an energy ball, which will suck you in and stun you for a short time. She will also attack using a laser from the jewel between her breasts, which will sweep across the field. Dark White in weak against Blunt attacks, so using Break patches is helpful
