Kobold is a dog-type beastman monster covered in fur with a petite body that widely inhabits various regions in the world of Arcania. They are mostly harmless monsters that would not attack humans. Kobolds have the humanoid appearance of a young dog girl. All Kobolds are females and can only bear offspring by mating with human males.

Kobold's thinking is mostly simple and instinctive. So when they want affection from their master, they will be upfront with their feelings and just snuggle up against him with their entire body.

They are also very expressive with their emotions; if they are happy, they will smile fully and wag their tail, they will lick their Master's face to show affection. If they are sad, their eyes will become teary, and their tail and ears will droop weakly. They express emotion with their entire body, not just their facial expression. It is said that they are so lovely in appearance that their master will end up being mesmerized and become infatuated with them.
