Yeah...... the only reason why this official art (the tag says so) doesn't bother me is that Katsuragi is clearly gay......
I mean, sure, I'm a fan of Yuri who does get excited over the slightest subtext, but even I wouldn't appreciate stuff that stirs up things that really ain't there......
The series is basically a Ikkitousen-style fighting games where even a single breeze can utterly destroy their clothing, thats the whole point of the fights in the games released so far XD.
But, if those who start the series just because of this mischievous publicity then Roma is gonna burn in fire with their bitching because I can swear things like this won't happen, maybe some groping that you can find in any ecchi series but nothing beyond that.
