This anime is based from the game. I learned that recently and honestly, the anime adaptation is really great. Especially the art. It has a cg opening sure but unexpectedly, most of their performance does not use cg throughout the season. The songs are great, I kind of wish they have a merch and characters are cute too. Each one has her own style of cuteness and attributes. The story though is pretty mediocre but nonetheless, I enjoyed watching it. Art style of anime is great, even when they aren't performing. Re: Stage! has five main groups but only three of them mainly made aperformance; the other two made an appearance but only for a while and didn't perform. I wish this anime had more audience though. Here's hoping for season 2; hopefully we'll see more of the other two groups if ever season 2 was announced?
