Patricia Haruna
is Serena's very beautiful teacher. She often scolds Serena for failing in her classes or eating in class.

In Sailor Moon Episode 2, she sent a letter on the radio station Love Line (which was created by Jedite) and as a result, her energy was drained by a flower broach. It was returned to her when the monster Fro was destroyed.

In the Sailor Moon R episode Detention Doldrums, she scheduled a date with her boyfriend Robert, but then found out it was canceled, putting her in a bad mood. She gave Serena detention for eating in school, and Ann detention for insulting poetry and reading it in an alien language.
