Milly, Suzaku, and Rivalz crash-land underwater and follow a mermaid to a civilization whose queen promises to keep them safe and help find the others.
- Ship Tease: Quite a bit in this chapter.
- When staying with the mermaids, Suzaku mumbles in his sleep about giving Euphemia some daifuku he made.
- In the same scene, Milly and Rivalz somehow end up sleeping together (though in full uniform since they're underwater), with Milly smiling and drooling a little bit.
