Clash with Lio

"“It’s you. You’re—” whispered Shiki, but before she could finish, the murderer had already started to make a beeline right for her. Knife in hand, he moved low like a sprinter, with no other choice in this narrow alley but to try and break past Shiki.
Shiki quickly drew her own blade with a practiced dexterity, but the scowl on her face then still told of her surprise. The shadow drew close, but with no human quality to its movement. He brought himself like a coiled snake, striking. And for a snake, even this narrow alleyway was more than enough to serve as a hunting ground. And even to Shiki’s trained eyes, the man moved much too fast for Shiki to reliably track.
And as soon as the distance between them was nearing a close, his pattern of movement changed. With a potent force, his legs folded and he jumped, all of it happening so fast that it seemed like an explosion of strength. And suddenly he was in the air, knife held pointed, then thrust with frightening accuracy at Shiki’s head.
A tiny glint in the darkness, and a moment later, the keening sound of steel upon steel. Another instant with a grating noise, as the murderer’s blade makes contact with Shiki’s own cross-guard. And in that instant, as both knives embraced each other like brothers, both combatant’s glances fell to each other’s eyes. Shiki, with narrowed eyes of hostility, and the murderer’s, with widened eyes replete with joy, and then the moment was quickly over.
With a visible grin, the murderer disengaged himself, turning Shiki’s blade aside, and leapt to the side, behind Shiki and toward the other side of the alley, successfully going around her. Like a spider, he landed, having leapt six meters with one jump. And then he stopped, stood there, breathing with a beastly noise.
And already, with his hunched form, and impossible movement, Shiki could clearly see that he had long been far removed from any common notion of humanity.
“Why?” he spoke. “Why won’t you take it seriously?” Fresh blood from the corpse graced his fingertips and the hem of his skirt, still dripping as he spoke. Shiki felt little need to answer him, but still looks at this man that looks so much like her. “You’re not the same. Not the same woman four years ago. If you were the same, you would’ve killed me, but you keep toeing that boundary. I’ve wanted you for so long. You, so much like me. But why?”"
