Description
Hidaka is a scientist affiliated with the organization known as FlipFlap, where he conducts research on the fragments of Mimi. His appearance is characterized by his pink hair and a pair of round glasses, which are a notable part of his look; when he removes them, he is revealed to be handsome. His typical attire consists of a white lab coat and work-style trousers, befitting his role as a researcher and inventor.

In terms of personality, Hidaka is depicted as being extremely high-energy and eccentric. His behavior is often described as loud, obnoxious, and that of a classic mad scientist, complete with feverish grins and wild gesticulations, especially when he is engaged in his work. This enthusiastic and somewhat unhinged demeanor provides a significant source of comic relief within the series. His primary motivation stems from his scientific curiosity, specifically his drive to understand the nature of the fragments and develop technology to interact with them.

Within the story, Hidaka serves a functional yet crucial role as the technical support for the main characters, Cocona and Papika. He is responsible for inventing various pieces of equipment used by the group, including the robot TT-392 and other devices necessary for their missions. He is the one who provides the scientific explanations for the phenomena the girls encounter, such as the concept of impedance, which describes how their emotional synchronization and the strength of their bond affects their ability to navigate Pure Illusion and transform. While often relegated to the sidelines, he has moments where his skills become essential to the plot and his energetic presence takes center stage.

Hidaka's key relationships are primarily professional, centered on his role at FlipFlap. He works alongside other members of the organization, supporting Cocona and Papika on their missions from a technical standpoint. There is a noted contrast between his real-world personality and a counterpart he has within the surreal dimension of Pure Illusion, where his persona is significantly calmer and cooler, suggesting a deeper narrative role that diverges from his usual comic relief character.

In terms of character development, Hidaka remains a fairly static figure whose primary narrative function is to provide support, comic relief, and exposition. The series does not focus heavily on his personal growth; instead, his value is demonstrated through his inventive genius and his unwavering, if often manic, dedication to his work at critical junctures. His notable abilities lie entirely within his scientific expertise. He is a talented inventor and engineer, responsible for creating many of the advanced technologies used by the FlipFlap organization, and he possesses a strong analytical mind capable of breaking down the complex phenomena of Pure Illusion into workable data.
