Tsurusaki (鶴崎 Tsurusaki?), or more often called Professor Tsurusaki (鶴崎先生 Tsurusaki-sensei?), is Hanasaki Tsubomi and Kurumi Erika's homeroom and Japanese teacher of Myoudou Academy in Heartcatch Pretty Cure!.
As a formal teacher, Tsurusaki wears her dark violet hair pulled up into a bun with a single strand loose. She has slanted, dark blue eyes and wears a gold suit-dress with an emerald top beneath it, grey tights, and black heels.
Erika describes her as being strict with her students, but kind to them and caring. She is slightly tomboyish.
Tsurusaki is first seen in her classroom when she presents Tsubomi to the class. Although Erika gives Tsubomi a hard time, Tsurusaki motivates her to stand up and try again, but is at the same time amused at Tsubomi's timid personality. In class, she catches Tsubomi talking, not knowing that it was Erika who started the talk and gave her trouble. After break, without knowing, Erika talks about Tsurusaki to Tsubomi.HPC01
Some days later, when Tsurusaki is talking with a colleague, she witnesses a Desertrian, made out of Myoudouin Itsuki's Heart Flower, just before it looks at her and her colleague and petrifies them both. Because of this, she is not able to see Pretty Cure in action, but is eventually saved when the Desertrian is purified.HPC07
