Kukuru Misakino  

Plankton, 海咲野 くくる

Kukuru is a high school student who serves as the director of a small aquarium located in Okinawa. Despite her youth, she possesses a lively and direct personality. Her deep passion for the aquarium motivates her to take charge with professionalism, even when it comes to addressing sensitive issues involving living creatures. However, fashion is not something that Kukuru is well-versed in. Currently, the "Gamagama Aquarium" faces challenges and may soon shut down.
