Dorus are the main security force of Orchid Rain Corporation. They are a lethal force composed of all female soldiers created by the hand of O.R.C.'s Vicard Von Ville. The high indoctrination they are subject to, in combination with the use of mind control technology, makes them incredibly fanatical warriors, loyal to their chief creator Von Ville to the very end. They are thought to go as far as revere him as a god.
When Vicard conceived the Doru Force, he made sure to only choose the most wanton, indecent and lewd girls possible. This is due to a limitation in Orchid's mind control technology, which requires a strong sexual desire to leverage its influence in the host's mind.
