Goliath serves as the Yozakura Family's guard dog and has been their loyal protector for generations—dating back at least to Mutsumi's great-great grandmother. He's an Okami Dog, a rare breed that's been selectively improved since the Mid-Edo Era, which explains both his unusual size-shifting abilities and his exceptional loyalty.
The dog is fiercely protective of the family and won't let just anyone near him; he's known to literally use his body as a shield if danger shows up. That said, he's not aggressive all the time—he's actually pretty calm when things are peaceful. It's only when he senses a threat or feels the family needs protecting that he becomes genuinely dangerous. Trust is everything to Goliath, and the Yozakura family has clearly earned his for centuries.
