The reason why Kazu was surprised is not because he saw a familiar face... but.. rather because.. he saw the expression on his face which he has never seen until now. The fight which he encountered was like a lump of boiling magma, flowing towards him... but only Kazu's body properly remembered the fights. Sometimes he would feel a murderous sense and he would get goose bumps.
