darcmistes might be correct, this is the embodyment of The End. He says so himself. "I am the white void. I am the cold steel. I am the just sword. With blade in hand shall I reap the sins of this world and cleanse it in the fires of destruction! I am Hakumen. The end has come."
Hell no. Hakumen's sword swings for JUSTICE and JUSTICE alone. He's one of the Six Heroes, for crying out loud. Bang is awesome, but he's just a hero wannabe when you get down to it. Old Haku is already a hero. Sure, he might try to destroy anything that stood in his way in CT, but he means to destroy evil. He's more accepting in CS.
