Description
Shōgo Mikadono is the heir to the major Mikadono Group conglomerate. Conceived via artificial insemination with an anonymous donor after his mother Kanoko and her husband Kumagorou faced conception difficulties, Shōgo was raised believing Kumagorou was his biological father. He later discovered the truth about his origins. Kumagorou, his legal father, fathered a biological daughter, Konoe Tsuruma, through another relationship; Konoe was given up for adoption due to family complications.
Shōgo possesses chin-length brown hair, gray or blue eyes, and a distinctive forehead scar from a childhood car accident. This accident caused partial amnesia, erasing memories of his early friendships with Konoe and Miyabi Kannagi, whom he rescued during the incident.
His personality blends kindness and sharp observational skills, enabling easy friendship formation alongside strong deductive abilities. He shows notable business acumen despite initial reluctance to inherit the family company. To claim his inheritance, requiring high school graduation and a spouse, he enrolls at Miryuin Academy.
There, Shōgo learns an illegitimate half-sister attends the same school and seeks a close relationship, prompting his investigation into her identity. Aided by Ikusu Mizutani of the Mikadono Group's Seiryuu Association, he analyzes clues and navigates complex interactions with female students including Konoe, Miyabi, Rinka Kunitachi, Mana Tendō, Mei Sagara, and Yuzurina Hōshō, some initially presenting as potential sisters.
Konoe Tsuruma is revealed as Kumagorou's biological daughter, initially making her Shōgo's half-sister. However, DNA testing later confirms Shōgo lacks biological ties to Kumagorou, nullifying their blood relation. Shōgo and Konoe develop romantic feelings, culminating in marriage. Concurrently, Miyabi Kannagi's father marries Kanoko, making Miyabi both Shōgo's stepsister and cousin.
His character arc resolves familial mysteries, reconciles past relationships, and fulfills the inheritance requirements through marriage to Konoe. Following these revelations, he embraces his role within the restructured Mikadono family.
