Gunfire was unusual, which caught Raven's attention as she was exploring still. Even more interesting, when she stretched out her empathic senses--was the very faintest and carefully 'blank' feeling that was in the same direction. So, heading in that direction--Raven was and was not surprised to find Okumura-san. Staying well out of range, while making noise to let her presence be known.

Quiet, not intruding overtly, but waiting and ready to listen or simply keep silent company if that's what was wanted.
