Chihayafuru season 3 episode 6
Episode title: Tatsuta River Ablaze
The audience at the Yoshino Tournament is taken for a wild ride with so many unexpected twists: Arata, the focus of high expectations, has been defeated, and Taichi, who only just reached Class A, advances to the finals. And now it's time at last for the final round between Chihaya and Taichi, teammates who have been practicing together since they were in elementary school. The odds are in Chihaya's favor, but Taichi isn't playing his usual karuta since he declared that he would defeat her in an official match.
