Calling It A Day
Even if using a different weapon than swords produced a slightly weaker version of attack than the single arc he unleashed before, it was still a fierce kind of attack.
After all the two moves he used were driven from sword based techniques.
"But the theory behind this worked best on thrown weapons… Arrows can't be held like swords. I can't stack the attacks on them… It'd be hilarious if I had to dance in front of an enemy before killing him… What will they call me then? The dancing crazy spirit master or what?"
He didn't get much disappointed by this failure. He simply tried to find other uses of what he discovered here.
After all, he didn't totally fail. He succeeded in executing his technique, but it required much more spirit power than he had.
So instead of using his spirit power while attacking with a sword, he thought about stacking these attacks over something he could throw later and sever his connection with afterwards.
