Oh god what is this a parody of. The entire "Sunrise X" is a reference to some mecha with that pose
@Zelinkokitsune It's a shot used in numerous Sunrise anime, beginning with Exkaiser the Brave (1990), first of the Brave/Yuusha series. However, it's become such a stock trope since then that the pose/perspective can't really be considered a parody of any single work.
