Movie
Description
Itoko Satō serves as the director of the Imaginary Science Research Institute, a facility dedicated to studying parallel worlds and related phenomena such as Parallel Shift and Imaginality. Within this role, she holds the authority to oversee the institute's research, which includes work on the Imaginary Elements Print, a quantifiable measure of distance between parallel realities. Her scientific expertise involves a deep understanding of both the complexities and dangers inherent in technologies designed to traverse these realities.
As a character, Itoko is defined by a strong protective instinct, particularly concerning her family. She is the mother of Shiori Satō, and following her divorce from Shiori's father, she raises Shiori as a single parent while simultaneously managing her demanding career at the institute. This protective nature directly influences her actions. When Shiori and Koyomi Hidaka attempt to use an experimental IP capsule to travel to a parallel world where their marriage remained intact, Itoko intervenes. She prioritizes safety and scientific responsibility over their personal desires, citing the significant risks involved in manipulating parallel realities.
Her motivations are rooted in both her professional integrity as a scientist and her personal commitment as a mother. She believes in maintaining ethical boundaries in research, even when faced with emotionally charged situations. This is further demonstrated by her later romantic relationship with Shodai Hidaka, Koyomi's father and a fellow researcher. Their decision to marry creates a complex family dynamic, as it makes Shiori and Koyomi step-siblings, a complication that directly motivates the young couple's desperate attempt to find an alternate world.
Itoko plays a crucial role in guiding and shaping the story's understanding of its core scientific concepts. After a critical accident during one of Shiori's Parallel Shift attempts, which leaves Shiori's physical body brain-dead while her consciousness is stranded, Itoko works together with Shodai to explain the situation. They clarify the scientific principles behind Shiori's condition, including how the timing of an alternate Shiori's death coincided with the original Shiori's consciousness shift, leading to the separation of mind and body. Through her work overseeing the institute, including studies on Optional Shift for controlled travel, Itoko consistently fulfills her duties as a scientist and administrator. Her development is seen in how she balances these duties with her evolving personal relationships, ultimately defining her as a figure who must navigate the intersection of groundbreaking science and profound family consequences.
