The EM-J2-3a is the most advanced android offered by the company. There is nothing too challenging for the J2-3a to handle. Douryo means companion in Yamataian.
The Douryo has a human appearance, the usual two arms, two legs. The toes are separated, as are the fingers. The fingers do have fingernails and swirls typical of fingerprints. The Douryo has synthetic hair typically straight and styled to the owner's preference.
The Douryo has a face capable of duplicating any movement and expression that a human one can. They can blink their eyes, and their mouth moves when the speak. Their eyebrows are made of synthetic hair. The Douryo has a tongue, teeth, and uses a cybernetic voice box located in the throat. This gives the android's voice a more human sound than the EM-J2-1a Geboku Android (Basic).
While the body can be made to appear male or female, the Douryo is anatomically correct. The owner can chose to have the unit equipped with pelage. However, while the basic Douryo appears accurate the sexual organs are non-functional. The unit must be upgraded to enable that function.
