You bumped into someone when you turned down the hallway. Who was it?

"Do you want to be more careful and watch where you're going?"

You heard a very threatening voice, as if it was a death threat or something similar. You looked up and there you saw, in the hashira of the wind, Shinazugawa Sanemi standing in front of you with a intimidant posture. You were just looking for the patron around the mansion, but when you saw him you got scared!
