After gaining the weapons, your girlfriend felt pain in her body, and her head split into 2 heads. 1 side an anthro tiger, and the other an anthro arctic wolf. Both of them panicked, after noticing each other. "WHO ARE YOU?" they shout, and suddenly felt the rest of them separate, until they both became 2 bodies, instead of 1.
The anthro girl on the left was a blonde tiger girl with orange fur that came with black stripes, while the other on the right was an arctic wolf girl with black hair, and white fur. Both of them were wearing the same body armor, and had the same mind as your girlfriend when they got up, you became both confused, and scared. First your girlfriend's house became a mansion with a fancy lawn, and now she has become 2 separate anthro girls wearing skimpy knight armor, and carrying spears.
