Yuriko Hori[]
Yuriko is Kyousuke's wife whom he met in high school (Chapter 119.7) where he was her classmate two grades behind her.
He was 18 when Kyouko Hori was born.
Kyouko Hori[]
Kyouko is Kyousuke's daughter who acts cold towards him and doesn't mind physically hurting her father as she performs an axe kick on him when Kyousuke tries to act cool in front of Izumi Miyamura. Later, when Kyousuke asks Kyouko to prepare him some food, she returns with a bowl of soup and purposely jams it into the back of his head. He then apologizes to Izumi for Kyouko's "crazy domestic violence habits".
Kyouko calls him by his first name (Kyousuke).
Souta Hori[]
Souta is Kyousuke's son. Although their relationship isn't shown much in the manga, Souta and Kyousuke have a good relationship. They seem to have similar personalities; both are chipper and love when Izumi Miyamura comes over. They also tend to agree on what they want to eat. Kyousuke's relationship with his son is much healthier than with Kyouko's.
