Kazuomi Hoshina, formerly known as Kazuomi Ichinomiya, serves as the managing director of Easter Company. He is a middle-aged man who acts as the stepfather to Ikuto Tsukiyomi and Utau Hoshina, and was once the superior of Nikaidou and Yukari. After failing multiple times to obtain the Embryo, he grew fearful that Gozen might abandon him. Consequently, he devised a plan to brainwash Ikuto to gather X-Eggs.
Kazuomi harbored jealousy towards Alto Tsukiyomi, believing him unfit for the role of Easter's head. He considered his grandson, Hikaru, more suitable for the position. Although he saw Ikuto as competition, he decided to use him as a puppet to lure the Embryo. Following Alto's disappearance, Kazuomi coerced Souko Hoshina into marrying him, showing no concern for his own grandson.
In Chapter 33 of the manga, Kazuomi realizes that the Embryo appears only when X-Eggs are purified, leading him to set a trap for the Guardians. Ikuto refers to him as "Mr. Director." As the story progresses, Kazuomi is depicted as abusive towards Ikuto and ruthless in his methods. He brainwashes Ikuto, compelling him to comply and undergo a Character Transformation with a black egg.
