The funniest thing about this is that a maximally conventionally attractive, vapid, go with the flow himbo whose job is just "war" and an equally attractive, aggressively positive power girl with 40 disparate careers being used as propaganda emblems for the Space Marines and Sisters of Battle is extremely fucking canon for Warhammer 40k.

Possibly they'd be introduces as a couple to push public favor for a joint sister of battle/ultramarine operation.
