I don't even have words to express how much I love Bang Dream and its characters, especially Toyama Kasumi. The story of the game and the anime are very engaging, the characters are charismatic and have a lot of personality, the music is to please many tastes, and the seiyuu are also very charismatic and quite talented. Some people are prejudiced against the anime from the second season onwards, because of the CGI, but in my opinion it has been improving more and more, and I also think it is much better than the animation in the first season, apart from the sexualization that ithad before.
Watch the anime, play the game, also watch Garupa Pico, the movies, I guarantee you won't regret it!
