I'm interested in this game and thus I will criticize it about dumb decisions like this character design. It's extremely jarring in the game's context. There's a fucking war going on and they decide that's the perfect situation where they literally bring out the big guns & put them in the center of the screen. Like, it not only objectifies women, it assumes all men are the kind that they just HAVE to have titillation in the middle of the battleground in every game, otherwise they lose interest. It cheapens what otherwise looks like an interesting premise. I have no problem with pervy games. Let Senran Kagura be Senran Kagura. But this is not a pervy game so there's really no need for such character designs. It's just off-putting for the people who aren't desperate for bewbzz. Besides, this game doesn't exist in a vacuum and doesn't get a pass just because it's Japanese. These past few years have shown how problematic the treatment of women is still in this medium (& all entertainment), so yes, silly shit like that character design do warrant criticism.
And yes, the designs of the protagonists (?) don't really make sense either, but JRPG protagonists not dressing up for war is something of a staple for the "genre".
