Episode 5
Nina and Michiru meet by coincidence at the park while Nina was filming a livestream. Nina is happy to know humans were watching her. Michiru is unbound and asks about her father. Nina denounces him, and explains that her grandpa was caught and eaten by humans, or says her dad. She doesn't believe him.

Upon finding out Nina was listening to human music, Flip forbade her from leaving the house. Nina then shows Michiru a box of knick knacks, among them a lone earbud. Michiru thinks back at the time Nazuna and her used to listen to Night Running together. Nina asks Michiru if she wants to go back, but she replies she can't when she looks like this. Michiru says she wants to go back. Sparks fly, and she suddenly turns back into a human. Michiru is elated.

They both go to the beach and sunset. Nina says a girl named Lisa from Facelook invited her to a party in the mainland. Michiru agrees to go. Flip returns home and with presents for Nina, but she's nowhere to be seen. The bodyguard does a full cowing and apologizes.

Night falls and finally arrive on the mainland. A bike cop passes them not suspecting a thing. They reach the party where people in masks are dancing to EDM. Night Running begins playing and Michiru reminisces her memories with Nazuna again. Nina interrupts her and asks if she's okay. Lisa walks up and greets Nina. Nina is elated and jumps but accidentally turns into a dolphin. Lisa is surprised she's a Beastman, but doesn't react negatively. Nina and Michiru are both shocked at the reaction. Lisa introduces Nina as the special guest for the Beastman themed party they were having.

Meanwhile at the party, everyone is cheering Nina at the pool. Michiru wants to go home because she feels something is off. Nina takes this wrongly and thinks it's because she's the popular one at the party. Nina refuses to go home. Michiru is feeling down and asks herself what she is doing. When Michiru walks out of the bathroom, Nina is trapped in a tank and is about to suffocate. Lisa had placed her in because she thogught dolphins needed water to breathe. Michiru transforms back into her beast form and punches through the glass tan with her Gorilla Punch. Nina coughs and is finally able to breathe. Michiru says it's time to go home, and Nina nods in agreement. Lisa is out of words. The group depart the mainland on Marie's boat.
