Rowena serves as the timid secretary to wealthy antagonist Grings Kodai, her nervous demeanor and need for reassurance during Zoroark’s illusion displays masking a sharp intellect. Glasses and black hair styled in side-buns secured by yellow hoops complete her professional facade—a composed yet anxious assistant in a white collared shirt, gray-and-black blazer, skirt, and dark stockings.

Unbeknownst to Kodai, she operates as an undercover journalist allied with reporter Karl, investigating Kodai’s exploitation of media and ecological sabotage in Crown City. Shedding her glasses and loosening her hair signals her shift from meek subordinate to resolute investigator, pivotal in aiding Ash’s team to expose Kodai’s theft of the Time Ripple’s energy two decades prior—a crime that ravaged the region’s environment.

Using an "Illusion Canceler" mirroring Kodai’s own tech, she pierces Zoroark’s deceptions while covertly gathering evidence. Her infiltration culminates in hacking his network to pinpoint the Time Ripple’s countdown clock, enabling his confrontation. Public dissemination of her collected proof ensures Kodai’s arrest, after which she departs with Karl, Zorua, and Zoroark to their homeland, her tall, slender frame now relaxed, pink eyes unobscured, hair freed from its bun—a visual testament to her reclaimed autonomy.
