- The scene at the end of the final episode where Izumi Himuro hugs Ryo Hayakawa to cheer her up after they lose the semi quarter final, with the hope of maybe trying to go farther next year.
- Every single word and note of the ending song, "PASSIONATE DAYS". Like the epic opening song, it's sung by Ryo and Izumi's seiyuu, and seems to be from the POV of Ryo and Izumi years after the events of the series, and high school. The dialogue from the bridge:Ryo: "It was at the tennis court when the leaves were budding, wasn't it? When I first met you, the sunlight was flowing all around you, and you shined so bright that it was hard to get near you."Izumi: "Back then, I tried hard to keep up my heroine facade, and couldn't take my mind off your gaze. But perhaps what I wanted was to open my heart and make a friend."
