Chihayafuru the 1 and 2 season were great and fun but 3rd is more dark and sad. I prefered previous season than that. Main characters were beautiful and clothes. The ending is open. They settle on year in 3rd series. Authors could make shorter challenges in karuta for episodes. Everone wants to get better in karuta plays but they must pay for that. They must choose between friendship, love or rivalisation to gain their goals. You feel that series is more cold and sad. Feeligns can change in to more negative. Characters become more egist than previous seasons. On 3rd is more emotional than gamein karuta.
