A to Z Challenge - B is for Beheading

I'm doing one story throughout the Challenge.If you're just joining me now, please start with A is for Abby.

B IS FOR BEHEADING Another coming behind you! Tawa shouted. And it's a big one!
"A little busy with the two in front." Abby hissed as she ducked under a massive set of claws as they raked through the fetid attic air. Still crouched, she spun to hamstring the first monster with one glowing sword and thrust the second blade up into the gut of the other beast. The blood was hot and black as it splattered over her, making her stomach churn.
What did you want me to do? Stare him down my my unblinking button eyes? Tawa snorted.
Abby twisted around to slash the injured monster's bulbous eyes and face the third ugly thing behind her. It was indeed a big one. Likely the original monster in the attic. She circled around it, stepping over the twitching bodies of its pack. Its gigantic fish eyes followed her every move.
"Big eyes all the better to see me with and big claws all the better to tear me apart. These guys are fast and wary. Any suggestions, boss?" Abby was panting. She had taken five down already and she didn't think they were dead. If she didn't take out this huge fellow swiftly, the others might rise and she'd be their next meal.Take off its head. It's the only way. This one's powerful. The stuffed hippo's tone was tense. Abby grunted for want of more info. Get behind it. It can't get you with either the claws or fangs that way.
"Yeah, so easy. It's totally going to let me do that." Abby could feel her skin prickling. If she didn't make her move very soon, the monster would come at her. She wouldn't win that fight. There was no way to behead it in one smooth move either.
With the tips of her blades, she cut the straps to the carrier that held Tawa on her back. Having an unassuming second pair of eyes had saved her life several times. As the hippo slipped, Abby caught her with the flat edges of her swords and threw Tawa at the monster.
Tawa shrieked and the beast's first instinct was to catch her. As it did so, Abby leapt to one side and somersaulted to stand behind it. She rammed her swords into its neck and yanked them outwards. The monster's garbled wail rattled the single window, but she didn't hesitate in slicing one blade through the top of its spinal column and severing the behemoth's head from its body. The head hit the floor with a meaty thud.
