Feelings I Can't Say (言えない心, Ienai Kokoro)
Hanon Hosho airs her disapproval to Lucia's new relationship with Kaito, since mermaids cannot reveal their identities to a human directly, as this will cause them to turn into sea foam. Despite this, during a festival later, Hanon, too, finds love. The mermaid Lucia prays Kaito to "find" her. Hanon's mermaid form is also revealed as the Mermaid Princess.

- This is the first episode to have somebody hurt.
- When Lucia was falling, and Katio got bloodied, it will be Lucia to be bloodied, not Katio.
