When the... creatures appeared, Masamune had been rather relieved. No more strange people. No more questions. Right now, there was just one thing that mattered. 

It was a fight. 

When the monsters charged, Masamune was full of life and ready to fight. Even as the others brought out their own, strange weapons Masamune pulled out his six swords, the dragon's claws. He did battle as he knew how to, slicing and slaying all in his path. 

However, it was then that the enemies did something that he found his opponents had a very annoying tendency to do. They stopped. 

Ceasing his battle, the dance of death that he brought upon the creatures, he simply stopped. Keeping his swords in is hand, he simply watched, ready to continue should hostilities continue. While he whistled at the tower that rose from the sand, it was now one of many wonders he would have to process later.
