Peach Mermaid, Volume 3 (Peach Mermaid #35-48)

Rune used to live on the ocean floor with the other mermaids. Now she's living on the surface with Riku, her first love. If she can be with a human, she'll turn into a real girl... but when things start getting steamy, her legs turn back into tail fins. The bond between Riku and Rune grows stronger by the day, but time's running out for their interspecies love story. Don't miss the final volume!
