Well when I finished the season 1 of this I thought there will be no season 2 tbh the anime(Love Live 2) is great it started with a great story and it ended very well. I had no regrets watching this anime, I didnt even jump any scenes from watching.
In the art, I really like the art you wont be disappointed by it and the characters, yes the characters, the characters are relatable in real life because there are some people who else had the same attitude on the characters aswell.
Conclusion, anime is great, the story was a masterpiece, I love the characters, and finally it has a great ending.
