He looks...
Tall and well-muscled, Osamu moves with a catlike grace, each step carefully measured and precisely calculated. His fur is dense and more on the bristly side, with both his cheek and tail fur in particular looking more wiry and disheveled than the rest of him.
More suited to mountainous terrain, his coat is swathed in a monochrome palette ranging from light grey to deep charcoal, with two sharp silver eyes breaking up the otherwise muted coloration of his person.
He is a wolf of excellent posture and built to fight, but there is no malice behind his stoic gaze.
