Alphonse only continued to guard against the incoming torrent of bladed arms, his own claymore glancing off of the them with heavy sounding metallic clangs as the look on his face was now becoming more and more angered the longer this thing continued to press him. This thing was relentless, but Alphonse was about to show it that he wasn't playing around anymore. Finally, in a fit of rage, Alphonse altered his stance so that his blade caught two of the Granaldo's arms with his claymore, growling at the thing furiously then used all of his proverbial might to shove it back hard a good distance.
"That's IT!!!" Alphonse shouted out, now having finally have had enough of this thing. "Time to put you out of your misery!" He snarled again as he once again held his claymore out in front of his body once more, but tightened the grip on the handle to a harsh degree to a point where the knuckles of his right hand could be seen turning white then lowered his head for a moment.
Suddenly, an encircling aura of orange swirled out all around Alphonse's body, giving off a sound of a scorching wildfire. A moment later, Alphonse's head lifted up quickly as his eyes narrowed at the Granaldo.
"OVERDRIVE SLASH!!!" Alphonse shouted out and within the speed of a thought, Alphonse seemed to have vanished from the battlefield with how explosively fast he moved towards it only to move right behind the Granaldo with his blade already extended for maybe a split second before he vanished a second time, this time appearing to the creature's right with the weapon extended again. For a third time, Alphonse disappeared yet again, only to pop up on the Granaldo's left with his blade having completed its deadly arc again, but for a fourth time Alphonse seemed to vanish yet again only to reappear in front of the creature, only to be seen with his blade held upward, it having already completed the same low to high arc to knock the Granaldo into the air above them.
"Here... We... GO!!!" Alphonse shouted out as he pushed off of the ground and literally flung himself after the creature at the same frighteningly quick burst of speed but cocked the blade back in a deep angle, looking to split the creature down the middle cleanly. At that moment, a fiercely crackling jolt of energy ripped through the claymore as he then brought it down hard onto the Granaldo's head, scoring a critical blow onto it.
With the move completed, Alphonse dropped down to the ground onto his foot and a knee as his claymore smashed into the dirt, his head lowered and his eyes shut.
