Hemiteos Unit

The Hemiteos Unit (ヘーミテオスユニット, Hēmiteos Yunīto) are an organization of special technologically-enhanced fighters in Black★★Rock Shooter DAWN FALL and Black★★Rock Shooter BEFORE DAWN.

History
The Hemiteos Unit were originally developed to protect Project Elysion and serve as its "trump card". However, when Artemis turned against humanity and rendered the project a failure, the Hemiteos Unit instead became humanity's guardians, fighting for their sake in the war against Artemis.

Only girls with the dormant Hemiteos gene were eligible for conversion into a Hemiteos Unit. This is carried out by activating the gene with a special drug and the use of DNA computer, which in turn can artificially enhance muscles and produce nanomachines to sustain the body, effectively turning subject human into a supersoldier. The Hemiteos gene is not present in Y chromosomes, hence Hemiteos Unit candidates are limited to females only. Furthermore, the gene would not be activated if the subject human is past a certain age, as it was with Jessica, who failed to become a Hemiteos Unit when she volunteered for the program.

Etymology
Hemiteos is derived from the Ancient Greek word ἡμίθεος (hēmítheos), which means "demigod".
