Family[]
Naozumi Miyamura[]
Iori and Naozumi are happily married. In their youth, they were friends who lived close by to each other. Iori gave Naozumi a bead ring that she made, which became a symbol of their relationship. Before they started dating, she was worried that she was too childish while Naozumi had lots of female friends who looked much more mature. However, that was mostly one-sided affection towards Naozumi, so she had nothing to worry about.
Izumi Miyamura[]
Iori is very strict with Izumi as she often forces him to do the things she doesn't want to do, like sweeping outside the store on cold days, and making him house sit if she goes out. She also acted as his disciplinarian, scolding him for doing things like making pen towers or ripping up too much paper. However, she does not scold him for getting ear piercings in middle school; she only complains that "does [he] really have to get [his] pillow dirty?".

Kyouko Hori[]
Iori and Kyouko meet when she came over to Izumi Miyamura's house when he caught a cold and were on good terms, much to Izumi's surprise. This is seen as Kyouko help with chores (like laundry and washing dishes) and even called her "Mom".
