What is limit? and why is it nasty?

Bam!

She crushed the door beneath her.

Raw strength. Just pure raw strength it was.

Everyone was amazed by her power. Dressed in an all-black gown, she had a long overcoat draped by her shoulder.

"As if I am letting this whore take advantage of you" She skillfully brought out sharp blades from her inside pockets. The blades were a weapon attached with a handle. It was made up of special alloy, dipped in magic, its blades shined giving the illusion of starlight.

Moon who was attacked so swiftly backed away from Severus.  Her cheeks got grazed by her blade, and black blood dripped down. Everyone's breath hitched when they saw how fast this unknown woman was. Her strengths were on another level. Despite being best in their kingdom, they were not even able to touch a strand of Moon's hair but here, this girl managed to graze her in her first attempt only.

They were all awed and their hearts were filled with respect for Desella.
