Black Bearman

As I had activated the 'First Boost,' and strength like never before had spread in my body with the speed that shocked me.

Earlier it used to take few microseconds for the power of 'First Boost' to spread through me, but this time it is instant, and the strength that had spread through my body many times greater than before.

The changes that Diamond Seal had brought seemed to have made my runes even more efficient. 

"World Striker!" 

While I was shocked with the power of the first boost, the Black Bearman attacked, and its attack was very powerful. 

Black Runes have spread across its whole hammer, and it looked like it did have the strength to strike the world. Though I know there is a mental attack mixed in it to make me feel that way, I still couldn't help but be impressed by the power behind the attack.
