The two women about to compete in a magical duel over you could not have been more different. That was part of what led to the fight - you like some variety in your life, after all. Even if it leads to you making incredibly poor decisions, like separately dating two very talented witches who had already publicly demonstrated their shapeshifting skills.
From one side comes Ellen, cracking her knuckles in anticipation. No more than 5 feet tall, the goth witch has an aggressive, competitive streak that belies her slender, petite build. Her pale white skin stands in stark contrast to her short black hair and red-dyed bangs over one eye, her black makeup and her lacy black outfit and fishnets.
On the other side ambles Tricia, towering a full head taller than Ellen. Unlike her rival in love, Trish has a laid-back, easygoing personality, and a very full figure. She has a mass of curly brown hair and big round glasses, but it's hard not to stray to the canyon of rich brown cleavage barely contained by a tight white shirt, and the skintight blue jeans hugging expansive hips below that.
The referee motions to them to stop, and they halt in their tracks.
"Not too close now", coos Tricia teasingly.
"Right", says Ellen with a sneer. "Wouldn't want to run into your fat tits".
"Bitch".
"Cow".
"Ladies, please", says the referee calmly as the two women stare daggers at each other. "You know the rules. One transformation at a time. You can't turn into something that has already been used in the battle. You have to change back before becoming something else. You are restricted to real, living animals - no imaginary beasts, plants, or humans, for example. The fight is over once one of you has taken enough damage to cause her to set off the academy's safeguard enchantments, resulting in a teleport to the infirmary. Now then, pace off..."
Ellen and Tricia turn their backs to each other and walk twenty paces off before turning around again. Once again you feel a pang of regret that you caused this, but you can't deny that the thought of seeing these two fighting over you is kinda hot. The referee pulls out a coin and a starting pistol.
"Call the flip please. The winner will get to be the first to transform".
"Heads!" says Ellen quickly.
"Tails", says Tricia with a shrug.
The coin flies through the air...
