In contrast to the more laid-back Miyako, Riko is serious, hard-working and diligent. She maintains a formal relationship with her students, insisting on being addressed as Hakozaki-sensei, rather than by her first name Riko.
She makes extra effort in her role as advisor to the student council, working late to help bring them old videos of previous plays and holding the training camp over the summer for them.
Riko can be quite secretive, as she prefers Miyako not to tell people about their relationship and living situation. Riko says that her dating pool is smaller with women compared to men, so Miyako is extra special to her.
Riko is in a live-in relationship with Miyako Kodama, although she generally prefers that this be kept a secret. The couple have known each other since college. Previously, she taught drama at another high school and is also part of a theater troupe with Tomoyuki Ichigaya and she currently teaches literature in addition to being the adviser to the student council.
- The name Riko means "reason, logic" (理) (ri) and "child" (子) (ko).
- Riko's surname Hakozaki means "box" (箱) (hako) and "cape, peninsula" (崎) (saki/zaki).
- Riko is actually shorter than many of her students (such as Touko Nanami and Sayaka Saeki), but she usually wears heels that make her look taller .
