Kaede Midorikawa is a main sales representative at Magilumiere Magical Girls Inc., serving as one of the company’s founding pillars and the first official employee alongside CEO Kouji Shigemoto. Standing tall with short brown hair and usually seen wearing a formal suit with a green tie, he presents a professional and approachable appearance that suits his client-facing role. His eyes are typically depicted as closed, expressing a sense of constant cheerfulness and emotional warmth. The name Kaede is not his birth name; it is a pseudonym he adopted during his time working as a host at a club, inspired by a character from the manga Slam Dunk.

His personality is characterized by a remarkable attention to detail, strong common sense, and a genuinely caring nature. He is recognized as the voice of reason within the office, often remaining calm and level-headed in situations where others might panic. His warm and friendly demeanor makes people feel at ease, a skill he leverages effectively in his sales work to build a vast network of contacts and anticipate client needs before they are explicitly stated. Despite facing dangerous and high-stakes situations, he maintains his characteristic smile and often serves as an encouragement to his coworkers, offering support and small gifts to boost morale. This outward kindness is a genuine aspect of his character, though he is later revealed to possess a much more serious and cold side that was hidden during an undercover mission.

Kaede shares a foundational and deeply loyal relationship with Kouji Shigemoto. They met when Shigemoto was a client at the host club where Kaede worked. At the time, Shigemoto was a magical girl technician grappling with the guilt of a colleague's death during a disaster he suspected was artificially manipulated. Recognizing Shigemoto's pure and serious commitment to his promises, Kaede offered to help him find evidence and protect his dream, leading to the two of them founding Magilumiere together. Kaede acts as Shigemoto's trusted right-hand man, often handling business matters and providing crucial emotional support, particularly after the death of Shigemoto’s sister. His relationships with other coworkers, such as magical girl Hitomi Koshigaya and employee Kazuo Nikoyama, are similarly warm and supportive; he is known for bringing food to Koshigaya and offering encouragement to Nikoyama.

Kaede's role in the story extends far beyond his official duties. During a major crisis where Magilumiere was dissolved after being falsely accused of causing an incident, Kaede took on the perilous role of a double agent. He officially went to work for the rival Kamakura, the individual suspected of orchestrating the company's downfall, all while secretly gathering evidence of Kamakura's crimes, including proof of a control chip used to manipulate anomalies. This mission required him to suppress his usual friendly personality and work undercover for ten years to gain access. The operation reached a climax when the evidence was discovered, and an associate of Kamakura triggered a self-destruct mechanism on the chip, putting Kaede's life at risk with a complex password that seemed impossible to crack. Through the collaborative effort of the Magilumiere team, they managed to input the password and save him just in time. Following this rescue, Kaede returned to his original role at the reconstituted Magilumiere company.

In terms of notable abilities, Kaede excels as a salesman and negotiator, able to anticipate what people need and maintain meticulous organization of important documents and tickets. He has a talent for procuring rare and thoughtful gifts on short notice. Beyond his sales skills, he is portrayed as highly competent at multitasking, handling multiple inquiries simultaneously, and is also skilled at video editing.
