What does the God knife do? The God knife has a special kind of blade that can change it's appearance and slays Gods. In my case it can change into a sword, a scythe, a celestial bow. The bow has several arrows that can change their form into human form. When an arrow snaps in two, it dies and cannot be repaired.
After the God's words, his theme song 'begun playing'. I changed my position. I tilted my torso and head backwards and raised my right knee in the air, while my hands glowed, the right was pointed to the ground and my left raised to the sky, my body forming a pair of scales(not literaly). "Libra's Gravity Force!" I yelled, smirking.
A golden magic circle formed under Sashiro's feet and raised him into the air slamming him on the rocky ceiling. I moved my arm in the direction of the left wall as the circle disappeared, he was enveloped by golden mist and slammed into the left wall. As I lowered my hand, he was slammed on the ground accompanied with a large crack from the stone path.
I positioned myself in a battle stance. He stood up grunting and launched a fist engulfed in crimson mist. I swiftly dodged the attack and cached him by the collar of his shirt, preventing him from falling into lava. He stiffed in surprise and wiped his head in my direction. I raised my eye patch and winked at him, giving him a evil grin. To which he blushed a tiny bit.
I threw him back on the stony path. He stood up and I let go of the eye patch. "Aww, come oooon! What are you holding back for?" I wailed in boredom. "Well, I know you can't keep up with me, so I decided to start it easy, just for you." He mocked. I could feel anger building inside me, but laughed it off. "I see what your doing there, trying to make me angry, are we? So I can go on rampage for you to win." I said mischievously. "Well. It's not working. Give me all you got!" I said.
He walked over to me and charged his fist at me, but I caught it gripping it tightly until I heard that dreadful crack of bones and took a step back. He's fist glowed crimson once again and so was I. The mist raised me from the ground as his fist launched forward I was slammed into the wall. I smirked and broke out from his mist, now beginning to fly by myself, of course, by covering myself with mist, gaining a grin from him.That's the benefit of being one of them.
He begun flying too and we charged at each other. As we kept attacking and dodging attacks, our mist remaining behind us and disappearing. Our mist was like two colors playing in the sky. I did roundhouse which he dodged and went for my stomach. I didn't have enough time to dodge and he pined me against the wall. I kicked him in the stomach and sent him flying into the opposite wall.
I flied after him and he put his feet on the wall and pushed to give him impetus and summoned his own knife, slashing at me. I dodged it barely, but it managed to graze my shoulder. I frowned and held onto the bleeding area. Blood was seeping out from between my hand and the shoulder.
We tried to slash each other more but only grazed our arms and legs. Eventually we got tired and flied back on the ground. Just when I got him off guard, I summoned my God knife and charged rapidly at him, knocking him on the floor. I put the knife against his throat, but not enough to kill him.
"I *huff* win. " I said sitting on his belly, pinning his wrists on the ground just in case he tries something. "Yeah... Trained you well... didn't I?" He asked grinning like an idiot. I laughed a bit,which is kinda unusual, and removed the knife from his pale skin. I 'sent' the knife back into the pocket dimension and rested my elbows on my knees. "I sure am glad we didn't wreck anything here." I said standing up and extending a hand for him to take, which he grabbed and instead of standing up he snatched me under, with him hovering over me. "You little sneaky, bastard..." I said grinning.
