The two can perform Wave Change to form Queen Virgo (クイーンヴァルゴ), who is capable of using aquatic attacks such as summoning a dragon made of water. She enters the story by posing as a new teacher at Echo Elementary. She is mainly in charge of harvesting Crimson Energy from fallen Noised Wizards. It's later revealed that she used to have a relationship with Shidō Akatsuki while he was a member of the Dealers.
