All the characters have excellent chemistry! Haruka and Kanata are absolutely cool. The character progression is great. At first there isn't much to be concerned about, or feel passion for, but then they start their rounds of volleyball and everything changes. Seeing a low-stress sports world open up for Haruka is amazing. Her happiness and enthusiasm are contagious. She revitalizes her cousin and together they learn from each other and build friendships. Opposing teams have backstories that show the dynamics of every match, and everyone finds each other's strengths and plays to them. It's epic. And as foranimation, the beaches are so beautiful it's basically as good as going to the beach.
