Beastman

Beastkin (also referred to as "human-likes") are humans with animal-like traits such as a tail or other physical attributes. A prime example would be Makoto Nanaya, a squirrel-type beastkin. Not much is known about the origins of beastkin and the role they play in society, but it is suggested that they are treated, at best, as second-class citizens, but at worst, as heavily discriminated and hated against.

Another example would be the Kaka clan village which is located underneath Kagutuschi near Area 28, but unlike Makoto, they were geneticlly enginered clones created from Jubei's cells. But due to humanity building a city over their village they are forced to hide beneath it in order to survive. But due to a genetic defecienicy the population cannot go beyond 100 members the reasons for this is unknown at this time. But it is believed that the village is on the verge of exctinction according to Litchi's story mode in Calamity Trigger.

However there are some exceptions to this such as the case of Kokonoe. She is very well respected for her intelligence and skills in science. Since she is the daughter of Jubei and Nine she has inherited both of her parents traits.

Trivia

 * There are few individuals who's origins are questionable such as Valkenhayn R. Hellsing. Since he is a werewolf he is neither human nor is he considered a beastkin.
 * Jubei may or may not be a beastkin due to the fact that he is more beast than man in appearance. He's basically an upright domestic cat with two tails who wears clothing and talks and behaves like a human being.
