Goliath

A black dog kept by the Yozakura family, born on January 17th. Descended from a line of specially bred dogs known as "Ōkami Dogs," which have been selectively bred to serve the Yozakura family. It is said to have served since the time of Mutsumi's great-grandmother, gifted with an exceptionally long lifespan and the ability to freely change its body length from 8cm to 30m. It possesses a fierce loyalty and a brutal nature, eliminating anyone who poses a threat to the Yozakura family. In addition to its own room, the dog has several storage sheds on the property, and a kennel equipped with a computer, communication equipment, and a secret passage leading directly to the mansion (which it created itself).
