The touch pool, where people are invited to touch sea creatures with their hands, is the biggest event of the summer at Gama Gama Aquarium; Kukuru, Kai, Kuuya and Fuuka are hard at work preparing.

Fuuka's mother comes to Gama Gama Aquarium to take her home, but she isn't ready to leave just yet.

Haebaru Chiyu visits from Aquarium Tingaara to study how Gama Gama does things; while there, she butts heads with Kukuru.

With the Gama Gama Aquarium soon to be closed, Kukuru is desperate to find ways to keep it afloat; she tries to figure out a way to market the illusions that people had been witnessing there.
