The character progression was more mental than physical, but still was kind of great.
Ark style was very good and enjoyable, I have nothing bad to say about it except the character design for Shuichi's power, I think it looked too nice and made some scenes much less edgy and serious as they should have been.
But if you're searching for a new yandere waifu material so go on and watch this series you can find many good clips with Aoki Clair here that will surely satisfy you.
Overall I would like to say that this series deserves a good old "7" for a score
