Description
Professor Ikeda is the head of the Ikeda Laboratory at the university research department where the main characters of the anime work. He holds the position of professor in the mathematical science information division and specializes in soft computing research. At around forty-nine years old, he is the supervisor and academic authority over the laboratory, where graduate and undergraduate students including Shinya Yukimura, Ayame Himuro, Ena Ibarada, Kosuke Inukai, and Kotonoha Kanade conduct their research.

In his everyday demeanor, Professor Ikeda is gentle, warm, and supportive toward his students. He comes across as approachable and somewhat absent-minded, and he does not project the formal authority or imposing presence that might be expected of someone in his position. He tends to view situations from the perspective of his students rather than maintaining a distant, professorial air, and he is quick to take an interest in anything he finds exciting or promising. Despite this relaxed outward manner, he has a formidable side. He has a heavily muscular and well-built physique, and when he is genuinely angered he becomes intimidating, with his muscles swelling and his temper becoming something his students fear. His physical strength is a recurring part of his characterization, and he has a habit of breaking objects, such as pens, when he is particularly emotional, whether from frustration or from excitement over a scientific breakthrough.

Professor Ikeda's motivations center on fostering his students' academic growth while encouraging their enthusiasm for science. He firmly believes that a healthy body is essential for a healthy mind, and he places importance on physical fitness alongside intellectual work. He is openly supportive of the unconventional research pursued by Yukimura and Himuro, who attempt to prove the existence of love through scientific experiments. His support, however, comes with conditions: he expects his students to follow proper scientific protocols and to produce meaningful results, and he does not allow their personal romantic pursuits to interfere with their academic responsibilities. In this way, he acts as both an enabler of their unusual project and a stabilizing force who keeps the laboratory functioning.

His role in the story is primarily that of a supervisor and mentor who validates the protagonists' unconventional thesis. By allowing and even encouraging their experiments into the nature of love, he gives the central couple the institutional freedom and approval they need to pursue their research seriously. He also provides occasional guidance about the balance between physical health and intellectual pursuit, reinforcing the series' recurring theme that science and human wellbeing are connected. Though he is not the focus of the plot, his presence legitimizes the laboratory's eccentric work and gives the students a clear authority figure to answer to.

Professor Ikeda maintains professional but enthusiastic relationships with all the members of his laboratory. He is the mentor and supervisor to Yukimura, Himuro, Ibarada, Inukai, and Kanade, and he treats each of them with consistent kindness and encouragement. His students respect him, and his authority is rarely challenged. His relationship with them is defined less by strict hierarchy than by mutual investment in the research, with Ikeda cheering on their efforts and occasionally offering wisdom drawn from his own experience as a scientist.

As a supporting character, Professor Ikeda does not undergo significant personal development over the course of the series. He remains a steady and dependable presence, defined by his constant support for his students, his enthusiasm for interesting research, and the striking contrast between his calm, friendly personality and his intimidating physical reactions when provoked. His notable abilities lie in his expertise as a researcher in soft computing and mathematical science, his capacity to supervise and validate complex student projects, and his unusual physical strength, which he sometimes channels into intense exercise or destructive reactions during moments of high emotion.
