Gender :: Male Birthday :: July 27th Age :: 32 years old Height :: 178cm Birthplace :: Kanagawa Prefecture Affiliation :: Gekidan Lalalai (Past), Representative Director of Kamiki Productions Family :: Eldest son Taiki Himekawa (born to Airi Himekawa) Second son Aquamarine Hoshino (born to Ai Hoshino) Eldest daughter Ruby Hoshino (born to Ai Hoshino) Characteristics :: The main villain and final boss of 【Oshi no Ko】. He is one of the other major figures in the work. He is the biological father of Aquamarine Hoshino, Ruby Hoshino, and Taiki Himekawa, and the ex-boyfriend of Ai Hoshino. Appearance :: His appearance in his teens was a handsome boy who was a dead ringer for his second son Aqua, except for his slightly longer hair. Even Ai, the work's top certified beauty, mentioned that his face was handsome when she dumped him after getting pregnant in their teens, confirming him as an officially recognized beautiful boy within the work. Even at the current point in time, he resembles Aqua enough that Akane mistook him for Aqua just by a passing glance, and upon seeing past footage, she confirmed he was the biological father due to the striking resemblance. In the art style, he is depicted with longer hair and a colder, more mature feel than Aqua. Like his ex-girlfriend Ai, he has stars in his eyes, and he maintains black stars at all times in both the current timeline and occasionally depicted past scenes. Personality :: In his childhood, he outwardly appeared as a pure and introverted boy, but like Ai, he was living a fabricated lie. There are hints that his home environment was poor, and he suffered continuous sexual abuse from Airi Himekawa; while recognizing this was an improper relationship, he displayed an affection-starved side that clung to false love. However, upon meeting Ai, who was similar to himself, he seemed to form some emotional bond, yet even after having children, he could not be certain of Ai's love and remained in an unstable mental state. After the breakup with Ai, his personality completely shifted from the past to a current state that is somewhat transcendent yet sly, showing a mysterious attitude where one cannot tell what he is thinking. He maintains his composure even until the moment he nonchalantly deceives and kills Yura Katayose, and he calmly appears before his children even while being suspected as the culprit who killed Ai.
