Heading to the roof seems like a way to potentially get cornered. Zishu isn't terribly concerned about that for himself, but most normal people he knows aren't particularly capable of traveling through the skies with a light tap of their toes. On the other hand, his current ally doesn't seem to be at all a civilian. Also, his footwork, at least, is more similar to that of an assassin than a soldier's--like Zishu's own.

Clearing a space around himself with a wide sweep of his blade, Zishu takes the opportunity to jump up, practically bouncing up the walls to a small ledge he can look over the entire area on. "Do you need help?" he calls down.
