Kerry represents the Wakaba Isshiki in this universe.

Kerry's personality is largely said to be nearly identical to Isla's. She is highly intelligent and knowledgeable in terms of cognitive psience and cooking, although she barely has any social skills to begin with. She is a workaholic and wouldn't let anyone disturb her from her research, especially when she knows that her job is life threatening. Despite this, she genuinely cares for Isla and is a great mother. Anything about her regretting birthing Isla is merely a fabrication made by Jace Hamilton in an unnecessarily callous means of quashing his opposition. 

Kerry was Isla ____'s mother. She was a researcher of cognitive psience, the study of the supernatural "cognitive worlds" within every human mind. Kerry was very brilliant and talented in this field of study, to the point that she was employed at a government-affiliated research facility dedicated to cognitive psience.

During her time as a researcher, she became affiliated with a government official, James Redbeard, who served as a middleman between her research facility and the government. Redbeard eventually fell in love with Kerry, although Redbeard's romantic affections were never reciprocated in the form of a relationship. Nonetheless, they came to deeply care for one another, with both actively expressing their fondness for one another. One such example was how Kerry, upon tasting Redbeard's original curry and coffee recipes, took it upon herself to refine the recipes into the signature recipes used in Cafe Redbeard.
