None of the designs so far catch my eye.
I thought it'd be a blue archive competitor when I saw the art style and that it was by Yostar but I don't know, I haven't seen any character so far that catches my eye and it really seems like they're a lot closer to Shironeko/Dragalia than any other game. Having also played both Shironeko and Dragalia for years, I can't think of the gameplay as anything special either.

The main character design feels like a huge fucking waste too. This should have been a playable character instead of wasting such an amazing design on the blank self-insert MC which sucks a lot. Overall, I'd say it's rather disappointing.
