Black Rock Shooter Wiki

Empress, leader of the Hemiteos Unit.

The Hemiteos Unit (ヘーミテオスユニット, Hēmiteosu Yunitto) is a type of technologically and genetically enhanced soldier in Black★★Rock Shooter DAWN FALL and Black★★Rock Shooter BEFORE DAWN.


Only girls with the dormant HET-1 "Hemiteos" gene were eligible for conversion into a Hemiteos Unit. This was carried out by activating the said gene with a special drug and the use of DNA computer, which in turn could 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 were 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.[1][2][3]

Hemiteos Units would form the mainstay of Peacebuilding Force's military strength. Luna Griffith also envisioned deploying Hemiteos Units as spacecraft crew for interplanetary travel.[4]


In response to Chivalrous Thieves Group's Camila, an enhanced fighter whose fighting capabilities were enhanced by activation of HET-1 "Hemiteos" gene and unmatched by contemporary weapons, Luna Griffith persuaded the United Nations to develop their own enhanced soldiers using the same technology to combat the terrorist organization.[5] The Type 00 series units were conceived in Lighthouse No. 1 in California,[2] and their deployment effectively eliminated the CTG as a threat, thereby completing one of the primary objectives for Project Elysion.[3][6]

However, when the AI core of the Project Elysion, Artemis, turned against humanity and rendered the project a failure, the Hemiteos Units had to battle against the rogue AI's Unmanned Forces, but they were overwhelmed and largely wiped out. The only known surviving members were members of Lighthouse No. 8: Empress, Dead Master, and Strength, but they too were eventually defeated and presumed killed in California until Empress's re-emergence in 2062. With the defeat of the Hemiteos Units, the Peacebuilding Force decided to abandon the Hemiteos program and Lighthouses in November 27, 2052.[1]
