Noting the desired individual's return, she asserts that the collected data from her various experiments is gradually reaching fruition, before dismissing those before her as mere prototypes. Upon word from another assistant that preparations have been completed, Shaula proudly declares that she will now prove her superiority to the other Gorgon Sisters.
Sometime later, Shibusen suspects her and begins their search for her. She is later seen at a public market place with a disguise on with the notion of selling scorpoin-themed jewelry.

When Meme was discovered to be one of Shaula's victims in mind control and Shibusen took custody of her, Shaula used Anya and Tsugumi's care for Meme to her advantage. After being free from captivity, Meme under Shaula's control took down Anya and then used Tsugumi as leverage. Shaula, herself, then took care of Shibusen's agents, putting them under her mind control. She then engaged Sid herself while controlling Meme to go against Akane. However, as Sid was engaging her, Meme stabbed him in the back. When he turned around to see he had struck Meme, he dropped his guard. Shaula takes advantage and that and kills Sid as a result.
