Osono's husband shows up throughout the film as a quiet, supportive presence in the bakery. He's the one who really helps Kiki get her delivery business off the ground—he builds her that iconic plate sign and sets it up in front of the shop. The guy's pretty sympathetic to what Kiki's trying to do, which is nice. He barely speaks though. Fans often note that he never actually completes a full sentence in the whole movie; he just makes little sounds or mutters single words like "look." His name is never mentioned, but honestly, his vibe is pretty endearing in that understated way.
