If you've watched season 1 you really don't have to read it because the anime stayed true to the manga while also expanding on some scenes, but the anime also takes it's art style from season 2 of the manga, so I'd say read season 1 if you're curious about how it originally looked
I watched the anime like months ago, my most recently memory was Kirio's disguise and plan during the festival. Maybe the manga has a different perspective but most of the episodes seemed like slice of life. So should I read from chapter 1 or at the end of the season 2 (I think?)
