Due to the insane pace we just exerted, I was not able to register what really happened during our clash. We moved thousands of times faster than the speed of sound, after all.
Not only did I perform Mother's most powerful move she taught us, although Big Sis could not reach that level yet, but I also used the unique skill I copied from her on our consummation to outstrip Melville.
I was sure she indeed hit me, as her blades were stuck on my chest, scary enough that she accurately pierced my heart. But upon seeing her current condition, I felt like a huge thorn had been removed from me and realized that I had managed to cut her in half.
Based on the positions of her two halves, she probably had her knees on the floor before her upper half separated from the lower part and collapsed behind her. Her upper half was lying on the floor with her arms and wings spread wide. Blood continuously came out of both the severed parts as well as from her mouth.
