Hidden Strike  

My sword was moving at ant speed compared to its burst into amazing speed. Its position changed in an instant from defensive to offensive.

CLANNG!

My sword moved toward its ax and, a moment later, appeared next to it before clashing it with great power that sent out faint ripples in the space and created a shockwave that pushed away from the Masters that were already fighting quite a distance in front of us.

A slight surprise appeared on its face seeing me taking its attack without the slightest shake, but that did not stop it from launching another attack immediately.

This bastard has first time appeared nearly a century ago, in a powerful ruin. Its last appearance stated it fighting against the human Grandmaster, the human Grandmaster had disappeared, and so is it.
