Description
Kashin Ikeda supervises the Ikeda Laboratory in Saitama University's Department of Science and Research. He leads graduate and undergraduate researchers Ayame Himuro, Shinya Yukimura, Ena Ibarada, Kosuke Inukai, and Kotonoha Kanade. His surname, Ikeda, combines the characters for "pool, pond" (池) and "field, rice paddy" (田).

Aged 49, Ikeda stands 1.85 meters tall and weighs 102 kilograms. Dark-haired and bespectacled, he typically wears a shirt layered with a sweater, presenting a broad, initially unassuming figure. His most striking feature is an exceptionally muscular physique, developed through dedicated bodybuilding pursued for personal calm and well-being. When angered or emotionally heightened, he visibly flexes, causing his muscles to swell into an intimidating presence. This habit frequently damages clothing, leading Ena Ibarada to ban him from wearing lab coats. During exercise, he opts for sleeveless shirts and black shorts, revealing his well-developed arms, shoulders, and pectorals.

Ikeda demonstrates consistent kindness and supportiveness towards his students, fostering academic freedom. However, he exhibits intense reactions when angered, often breaking pens he holds due to his strength. His MBTI type is ESFJ (1w2), reflecting a strong responsibility towards his lab members and society, adeptness in social dynamics, and a positive attitude. This type also notes challenges with interpersonal passivity and occasional relationship difficulties despite his expressive warmth. He values logic and order academically, intervening authoritatively during conflicts—like halting arguments over research methodologies—to restore focus.

Within the laboratory, Ikeda balances permissiveness with oversight, granting autonomy while providing guidance. He shows flexibility towards unconventional research, such as initially expressing shock but later endorsing Himuro and Yukimura's love experiment upon recognizing its scientific merit. He encourages expanding participant pools and mediates disputes, emphasizing collaboration over coercion. His leadership includes delivering motivational speeches to refocus the team. He addresses academic negligence sternly, as seen when chastising Kosuke Inukai for incomplete work.

His personal interests include bodybuilding as a stress-relief mechanism. He is married.
