It's kinda hard to follow. The characters aren't really introduced too well, it's assuming you've played the VN (which I haven't) and basically glosses over everyone in chapter 1. I'm still left reeling wondering who are these guys and why should I care about their relationship. At least the fanservice and pantsu are adequate.
Also wanna toss it out there, Noel and Akane's(?) armor are mostly realistic. Celia and Bertille(?)'s armor would make strikes to their chest easier cause of boob plate.
