He doesn't expect her to defend herself even though there's a quiet, buried part of himself that is surprised when she doesn't. It's his job though, as her self-appointed protector and he's more than capable, lunging forward in a blur of shadow and gray. He's smaller than the monster by quite a bit but his compact frame is entirely muscle and it drives him into the beast with more than enough power to knock it over. Once it's off its feet, it's easy for Cloud to deal with it in a violent slash of fangs. He moves almost too quickly to see and even the glow of his blue eyes seems to blur and trail.

He's a protector. It also means he's a killer. He does it with brutal efficiency and without a sound. When he's done, he shakes and his coat scatters blood, his and the monsters. His wounds are minor. Lifting his head he looks back at the blue hooded girl and exhales through his snout before starting forward again, one eye on her, pace a bit more hurried now.
