Alright, after seeing the 13th episode, here are my thoughts (and opinion) about this show.
This might contain minor spoilers! (Also, English isn't my first language so there might be errors, please mind them!)
The plot is a lot like Idoly Pride, if not exactly the same, but I won't go into the details of it, you'll just have to watch both of them and find the similarities!
The art is actually pretty good, the 3D feels fluid and it fits the animation, not too stiff and not out of place.
The characters are all likable and have interesting backstories. They all have unique character designs, like Shiori with her cat-like features.
The sound and music is really good, the songs are nice and I have them saved on Spotify already (plus the MV's are nice too).
Overall, this show is decent and enjoyable, the only nitpick I have here is that they almost entirely ripped off Idoly Pride. But, if you haven't watched Idoly Pride yet, you'll probably enjoy this more than me.
