Saru

Saruu is the pet dog of two of the World Nobles, Saint Roswald and Saint Shalulia. This dog, like all other Nobles, wears a helmet to "protect" him from the outside air. When we first see him, he's urinating on Devil Dias, a slave to his owner's. He has the appearance and color of the toy dog breed Pug, however his legs and body are longer than normal
