The only characters given last names in either the an9me or the manga are teachers (like Yoshinoya). None of the girls have family names mentioned. This could be a problem for fanfic writers!

It is also highly unusual in Japanese high schools to have everyone referred to by their personal name (as opposed to family name), especially by teachers. But this is part of the fantasy surrounding Hidamari Sketch -- the girls live by themselves and family is rarely even discussed,
