Kakuzawa Kyouju

As the son of Chief Kakuzawa, this mid-thirties academic possesses a diluted Diclonius lineage, characterized by diminished horns and a lack of vectors. During his university years, he played a pivotal role in recruiting Kurama to participate in Diclonius research. By a twist of fate, he later reappears as the university lecturer overseeing the course attended by Kouta and Yuka, connecting his scientific past to the protagonists' current lives.
