Of all the things Masamune had seen during his life, this definitely topped a lot of them. As he made his way through the ruins, he came to what appeared to be two girls lying on the ground - one, the one he heard call herself "Suwaki Moriya" seemed strange enough, but the other one looked like she was showing more skin than Uesugi's bloody ninja. 

And did he see one of them falling from the sky? 

Seeing the first girl fretting over the second, he wondered if he should call out to them and make his presence known. Heck, he probably already did with his shout earlier. 

"Hey," he said as he rounded a corner and approached the two girls, his eyepatch and swords probably giving off a less than pleasant impression, "Are you two alright?"
