With Shiro out of the way, Matt felt relieved to have the arena for himself as he began to hear the familiar bustle of paramedics coming in to take away the fallen merman. Good, now he could hurt the opponent and still attempt to keep himself alive in the process. He quickly studied his opponent, and through the thoroughly crooked grin, he realized this was an opponent that would have easily taken Shiro on in just a short moment of weakness from his part. Except, Matt felt ready to take him on. 

Soon, though, he felt claws against his skin, penetrating him in a way that was equally painful and frustrating. He yelled out in pain before he too bared the claws he thought he would never find himself using, and lunged at what he analyzed to be the weakest spot in the opponent; the area of his neck. While he was calculating, Matt was just as calculating but he wasted less time doing so. His claws bared - paining him because of how little he used them (he wasn't proud of having them) - and he dug into the creature's skin, watching as a liquid he could only guess was blood seeped out of the wound. 

Meanwhile, two mermaids came to carry Shiro out of the arena, over to where most merfolk went for emergency injuries. It was a small, faraway cove where mer of all kinds and ages bustled around, almost like a hospital. He was placed on one of the comfortable beds there, hidden away from the rest of the mer until someone more professional would come to heal his wounds as best as merfolk were able.
