The Power of Soulayer

'...'

Soulayer was the first to take a step toward Stark, the water beneath his feet creating a small wave as it was infused with powerful aura.

The area around them was filled with tension.

'...'

Stark would have loved to immediately dash toward Soulayer in the hope of killing it quick, but no matter how much he thought about it, THAT thing was ready for any of his attacks, basically, he needed to find an opportunity and then deal the maximum amount of damage to it. 

"SOUL STRIKE...!" and so before Stark could even finish thinking, Soulayer suddenly dashed toward the boy, closing the distance between in less than a second.

Some souls inside of the water emerged from below and placed themselves around the edges of the greatsword, as if covering it to give more power.

And they did, which is why it's called [Soul Strike].
