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
