The Eternal Summer of Beginnings!

Upon returning from Australia, Haruka gives his thanks to Rin and rejoins his teammates, deciding that he will start focusing on times and winning for the sake of reaching his new dream to swim in the wide open world. He then apologises to Makoto, who explains he is going to a Tokyo university in order to become a swimming teacher. On the night before the national tournament, the group reminisce about the past two years together, with Nagisa and Rei becoming emotional about Haruka and Makoto's impending graduation, though Haruka assures them will always be connected. Following a memorable experience at the nationals, in which Iwatobi manage to win, it is graduation time. Rin passes on the position of Samezuka's captain to Nitori, before telling Sousuke that he'll wait until he returns to the world of swimming. Meanwhile, Iwatobi bury a time capsule containing the sights they saw at the nationals, before joining Rin in a petal-filled pool. Everyone soon goes their separate ways, with Haruka and Rin soon facing off against each other in the professional circuit.
