You are missing out on a lot if you didn't watch this yet. The story keeps gets better and more mysterious with each season. People who haven't watched it yet thinking that it's just an idol anime or filled with rainbows, you're wrong. It's more than that. In short, this is one of the best animes filled with mystery, songs, comedy, every genre tbh. So don't skip it! Also for those of you who don't know this, the anime is adapted from the mobile game 'iDOLiSH7' and it's a very fun rhythm game and has the whole story till the end. It's still ongoing btw. So do try thegame out as well!
