Relationship with Hanako: She summoned the supernatural Hanako-kun to help her win the heart of her idol, Teru. While struggling alongside Hanako-kun, she finds a cursed matchmaking item called a mermaid scale and tries to use it despite Hanako-kun's attempts to stop her. However, she soon discovers that her senior already has someone he likes... Secret: By drinking the mermaid scale to meet Hanako-kun, she fell under the mermaid's curse and turned into a fish. By binding her fate with Hanako, the curse was halved, allowing her to return to human form, but she now turns into a fish whenever she gets wet. If a part of her body gets wet, pink scales appear there; if she is completely soaked, she turns fully into a fish. She returns to human form if dried with a towel.
