Like GF Kari or Kantai Collection, this is a show about quantity over quality, specifically with regard to “battle girls.” No two girls are quite alike in hair color, voice, outfit, or weapon, and it’s a collect-them-all vibe to them.
There doesn’t seem to be any angle that might subvert the standard magical/battle girl genre; they’re just in a bit of a performance slump and their instructors have decided to put them through more training.
While the main trio of Miki, Haruka, and Subaru are introduced and a few other relationships and personalities are doled out, it’s frankly a bit of an overload for me.
The line between entertainment and advertisement feels so very thin here, and the “Irousu” enemy is generic to the point of afterthought. If it’s all the same, I’ll go ahead and skip this one, which while not shockingly bad, is bereft of anything new or interesting.
