I have to stop this. Angel can't fight for that long, although he could. 

"It ends here." I say. 

I snapped my fingers. A pentagram appeared, red as blood, on the floor. I step in it. Red rays beamed down on me. I have to use this, although it probably will kill me, but what the hell. I created black vines, and they wrapped around her. She growled at me. 

"Y'know, I am so sick of fighting you. It's better to end this." I smile. 

My arms stretched out. I grew taller. My eyes turned black. I opened my mouth. Shadows poured out. Each one circled her occasionally cutting her arms. Blood came out of my arms and mouth as well. God, not much time.

The shadows grabbed her. I opened my mouth wide. A dark portal appeared in my mouth. 

"Have a nice ride." A shadow said. 

"Go back to the hell you came from." I echoed. 

They tossed her in. I closed my mouth. The shadow's faded. I began to shrink back to normal. I coughed up more blood. I fell to the ground. Angel ran to me as everything went black.
