Yeah I doubt it's promo art - the style doesn't look right.
Plus panty shots - I mean really
It's from Megami though, so.. I'm pretty sure they only do their posters from official art.
That, and it has that writing in the corner that tends to show up on official art.
Asmodeus's expression tells me all I needed to know... Poor Battler, again.
Battler doesn't look happy with what Dlanor just said...

Spoiler:
<<07151129>>
Eva: "What's with this set of numbers...?"
>>"I wonder what it is about..."
Battler: "Hmm...0715 is my birthday, that's what it probably meant, but I'm not sure about 1129..."
Jessica: "Birthday?"
Jessica: "Ah, can it be that: 0715 = Battler, 1129 (I-i-Ni-Ku) = Delicious Meat, something like this?"
Battler: "Hey, hey Jessica. If that's the case, I'm the delicious meat, who's gonna eat..."
...
"...me?"
<<Back of the hand, tip of the nose, and so on>>
Asmodeus: "Alright, so where should we stake you this time, Battler-kun?"
Satan: "Make up your mind and tell us, come on come on"
Battler: "Tsk, fine, do what you want"
>>"Alright then, I shall pick the back of the hand!"
>>"Then I will take the foot!"
>>"I'll have the wrist"
>>(Ronove?)"Oh, it seems to be pretty fun here"
Ronove: "Then I shall stake Battler-sama's [Beep----]!"
