Considering I would be hailing from a clan of Grim Reapers, it would be called "Instant Access....TO HELL! LMFAO". No seriously, it would be called "Instant Death"
I just get that grim reaper thingy, slam my hand on the floor, and some dark hands (in the form of purple shadows" would rise behind my foe, grab him, and bring him in front of me. I'll move my hand like if I'm taking his/her soul, hover a little above the ground, and use my grim reapers thingy, and cut his soul. Into TWO PIECES!
