Yoshino (吉野)
Voiced by: Aki Toyosaki
Chiaki's classmate. She seems to be the most responsible and level headed among the characters her age. Might have found out that Mako-chan is really Makoto, but she conceals whether she knows. The character introduction page of Minami-ke Volume 01 describes her "giving the impression of a rich girl", but this never comes up anywhere else, and is never mentioned again.
First appearance Minami-ke Chapter 003
