Mermaid/Relationships

Yashiro Nene
Initially, the Mermaid appears from below the Kamome Academy in order to take Nene as its new servant momentarily after Hanako-kun rescues her. According to the story, when a person swallows its fish scale, they are ultimately cursed to be transformed into a fish as a mermaid's servant. However, if another swallows a fish scale, they share the curse and form a special bond. However, she was stopped as she retreated from Hanako-kun's attack.

Hanako
Before the Mermaid was able to take Nene away in her fish form, Hanako-kun stops her, saying he hasn't granted any of the girl's wishes yet and therefore interrupting his service. The Mermaid refuses, saying he was a mere School Wonder, but retreats once Hanako-kun made a single slash on her.
