Goliath

Goliath is a mysterious black Great Divine Dog of specially enhanced breed, who has stood watch over the Yozakura family for more than a hundred years. Gifted with remarkable comprehension, he understands human speech and lends his abilities to a wide range of covert operations. His extraordinary physique allows him to shift his size freely—from as small as 8 centimeters to a colossal hundred-meter scale—while his remarkably tough skin can withstand blades and explosions alike. In everyday life, he carries a gentle temperament with a fondness for walks, yet the moment an intruder appears, he transforms into an utterly ruthless guardian, his devotion to the family absolute and unwavering.
