Kyousuke Hori is the husband of Yuriko Hori and father of Kyouko and Souta Hori. His work demands often lead to extended absences from home, resulting in periods largely absent from family life. Standing approximately 180 cm tall, Kyousuke possesses distinctive long, messy gray hair frequently covering his eyes and golden-brown eyes. He typically presents a tired or carefree demeanor. His appearance strongly resembles his son Souta, noted as so similar that Izumi Miyamura initially mistook Kyousuke for a significantly grown Souta. He is often seen smoking cigarettes upon returning home. Personality-wise, Kyousuke exhibits a playful, joking, and generally easy-going nature. Described by his daughter Kyouko as rude, selfish, and forceful, he tends to make light of serious subjects. He shifts moods abruptly, transitioning from tiredness to visible happiness upon seeing Miyamura. He is also characterized as frugal, refusing expensive family requests like Beluga Caviar or Shark Fin Soup. Underlying his outwardly confident behavior are traits of shyness, fearfulness regarding ghosts and horror movies, and social awkwardness. His family often treats him with mild neglect or annoyance, such as excluding him from meals or questioning how long he plans to stay during visits, contributing to his occasional feelings of being unwelcome. His attempts at humor or bonding, like inviting Miyamura to bathe together, sometimes cause discomfort. His background includes marrying Yuriko after she was his senior in high school. A past separation from the family occurred for undisclosed reasons, though he later returned to live with them. His career remains unspecified, with even Miyamura unaware of his occupation. This separation history and work demands contribute to family dynamics where Kyouko manages household responsibilities during parental absences. Relationships within the family are complex. While Yuriko and Kyouko often tease or ignore him, Souta displays more affection. Kyousuke develops an immediate and persistent fondness for Izumi Miyamura, whom he meets during a Christmas vacation. He openly refers to Miyamura as his "son" even before Miyamura's marriage to Kyouko, causing confusion among friends like Tooru Ishikawa. His interactions with others, like Kakeru Sengoku and Sengoku's father, sometimes create discomfort despite friendly intentions. Notable moments include his startled reaction upon seeing Miyamura's tattoos during a bath, leading to an apologetic bow, and his loud declaration of Miyamura as his "son" at Kyouko's graduation, inadvertently misleading bystanders. His development across the series depicts gradual, albeit partial, reconciliation within the family structure after his return. While tensions persist, moments of levity, like his exaggerated fright reactions and attempts at paternal bonding with Miyamura, add comedic elements. His role remains consistent as a transient but caring figure navigating his place within the household.
