Suddenly I felt energy run through me. I shot up and into the sky, with my body stretched out and shielded Neko with myself right as the death beam went through me, it pierced through the right of my chest, and all energy was gone from me. I fell down to earth like a dead weight. I looked up struggling to keep my eyes open, "finish her" I mouthed to Neko, she looked up at Yami and charged at her, then I saw my father, he had a look of horror on his face, I crashed into the ground, my father was by my side in an instant.
