The three were too busy acting as if they were tired from their earlier attacks. The looks on their faces told the onlookers that they had tried their best and had exhausted themselves when they had revealed their team combination attack that was also their trump card.
With the finale of the show, the three could finally retire from the fight with a proud expression in the name of recuperation so that they could contribute to the fight once again. In reality, they were in perfect condition and didn't need any rest at all but the masses didn't know that and believed them completely.
Zavier finally started to enjoy the thrill of the fight that he had been trying to suppress for so long. He didn't want to make it look like he was some battle crazed maniac but then he thought that no one would know anyway who he really was. So, there was no harm in getting a little carried away.
