Cute battle maid. <3
The card has the designation PRO-008 and while copies do exist, they have never been formally distributed.
The project was called MAXHEART, and it was the precursor to Immortal Emperor. A video exists on YouTube depicting early gameplay footage.
The game was about collecting gun-wielding maids to fight an army of cute androids who also had guns.
MAXHEART would be re-skinned to become a game about powerful mages fighting otherworldly creatures.
The promo card is likely to be given away as part of another event.
