Yukichi Kumamoto

Gets hit on by guys a lot (except Nosuke). Shishio's friend and Suzume's uncle. She's been living in his house ever since her parents moved to Bangladesh because of her father's job. He has a cheerful and carefree personality, but that doesn't prevent him from worrying over how Suzume's doing in school and reprimanding her whenever she gets a bad grade.

In Tsubaki-chou Lonely Planet, he's a customer that frequents the shop that Katsura works at. In a later chapter, it seems they've become good friends.
