The second season continues to follow the Mizusawa high school Karuta club as the main characters progress into their second year at school. It introduces two new freshmen who join the Karuta club: The first is Hanano Sumire, a girl with zero interest in Karuta who only joined because she has a crush on Mashima, and does not attempt to hide that fact, but is willing to learn the game just for the sake of being close to him. The second is Tsukuba Akihiro, a transfer student form Hokkaido, who has already played Karuta before, but unfortunately the Hokkaido version of Karuta uses different (wooden) cards and different rules (only the second verse of each poem is read), meaning that as far as mainland Karuta goes he's a beginner but unfortunately he thinks he's better than he actually is. Furthermore, he has three little brothers who idolize him, leading him to frequently trying to impress them even when it's really not appropriate.
SPOILER ALERT: Minor spoilers will follow, though all only about the first season. If you've already watched the first season there will be no further spoilers here.
The second season follows Mizusawa as they compete in the teams tournament, hoping to become champions, and their decisions how to have the newcomers participate as well. The tournament this year happens to attract a large amount of weirdos, leading to hilarious moments.
On the individual level, Ayase starts analyzing the current Queen's game (almost to the point of obsession) as she starts to become serious about her dream of claiming the title. The season also follows Mashima, as he repeatedly tries to win an individual tournament in order to advance to A rank, fighting mainly against his usual terrible luck.
Overall, this season, being the direct sequel of the first, gets in my opinion the exact same scores as the first. If you liked the first season you will like the second as well.
