The Dragon of the Void

S2: World Erupting

In the midst of the Clarenmont Forest two catastrophic beings were clashing at high speeds. Their auras could be felt by several kingdoms, even though the location of the battle was within the richest magicule area in the world.

Two godly beings encaged kicks and swords strikes that shook the air, causing countless sound bombs. The wind pressure of the sword strikes split the sliced through the clouds like a straight line. In the sky all can see lines between the clouds made from the strikes, showing the clear blue sky amidst a day that should have been covered by clouds.

If one can withstand the 2-dominating aura's, sound bombs, and rigorous winds, you will see two beings with blue hair clashing. They were both duel-wielding swords, dodging, and kicking at each other. 

Rimuru: I'm currently fighting Ciel with Zeothion(Demonic Sword) and Zuefion(Holy Sword). we've been training for hours without the use of thought acceleration. Moving place to place in the air at insane speeds. Our aura's spread through the world like wildfire. 

Ciel: Rimuru is improving a lot, but every now and then there are flaws I can take advantage of. Also, I've found a way to make the twin swords Rimuru's using stronger. As we continued our bout, I refined my movement more than before while pointing out Rimuru's flaws.

After a few more ours they stopped for lunch. During this time Ciel came up with an idea to make Rimuru's swords stronger.

Ciel: "Rimuru, could you lend me your swords?"

Rimuru: I kept eating the yummy sandwiches and gave Ciel my swords. "Mhm, here. Ah *much*" I bit down on another sandwich as Ciel examined the blades.

Ciel: I added more runes to the blade in order to combine the swords and sheathe into a magic bow. I engraved the runes into the hilts and sheathes of the sword. When I was finished, I said. "Zaoithin appear." The swords and sheathes combined into the chaos sword. 'Good they can still combine perfectly.' "Separate twin blades."

Ciel: "Now let's see if this works. Bow form." The two swords changed into bows. Zeathion changed into a bow that was red and black, with the string being made of a dark and sinister looking energy. Zuefion changed into a golden and white bow, with the string being made of a yellow and calming energy.

"Zaoithin appear." The two bows glowed and combined into a pitch-black bow, with a string made from an energy devoid of all light yet calming. "Sword form." Zaoithin once's again turned into its original sword form.

Rimuru: I stared at the bows and how it combined and transformed back to a sword. "That was so cool Ciel! How did you do that!"

Ciel: "I can do it because I analyzed rune magic and how it works. Want to try out your new weapons."

Rimuru: "Yeah! Gimme gimme!" I reached out to Zaoithin wanting to test out this new cool thing.

Ciel: I handed the sword to Rimuru. "I made it so you can draw the string with magic when it's separated so you don't have to use one at a time. Also, when in bow for say the command sheath."

Rimuru: "Separate twin blades." the swords separated, and I held them up towards the sky. "Bow form." The sheathes flew towards their respected blade, making the swords and sheathes glow. They combined into bows. I concentrated magic on the bows string and formed and arrow and fired. Two magic arrows: one of demonic power, and one of holy power blasted into the sky. 

After practicing for a few hour's Rimuru had the control to fire an arrow every second with once bow. Rimuru can now fire magic powered arrows twice a second thanks to having to bows. The longer he held the string and arrow back, the more power it collects overtime. It collects power from nature and the user. In this way, he could constantly fire one bow, while charging up a far more powerful shot with the other.
