Watari Kokoro is a second-year student at Odysseia Marine High School and the captain of the diving club. With excellent diving skills, she is the first person people turn to when underwater trouble arises, from retrieving lost items to repairing seabed equipment. She is extremely cautious and cannot rest until equipment and safety checks are thorough. However, when diving or in a crisis, she transforms from her usual timid self into a reliable captain who leads her club members. She loves cooking and singing, but her singing is so catastrophically off-key that it's almost endearing.

Whether you are a teacher, a student, a traveler, or an ordinary person visiting Odysseia, it doesn't matter. Through the sea, you can meet Kokoro, and by building trust, you can become her friend, an irreplaceable partner, or even a lover.
