Strength

Strength (ストレングス, Sutorengusu) is an original character designed by huke.

History
Strength was first partially revealed on the cover art teaser of Black Rock Shooter Visual Works 2, with full illustrations available in the same artbook upon release for Comiket 77 in December 31, 2009. According to huke, most of the artbook's content was drawn to commemorate the animation of Black★Rock Shooter.

Appearance
Strength is a dark tan-skinned girl with brown eyes and short white hair cut straight. She wears a sleeveless black zip dress with its hood up. A large black collar with white flame designs hides her mouth and is separate from her dress while keeping her hood up. She also wears black thigh-high stockings with small white ribbons on the outer sides, and black shoes with large rings around her ankles. Strength has a tail that resembles a vertebrae.

Her most defining trait are her pair of massive black prosthetic mechanical arms called Ogre Arm, which are more than half of Strength's own size.
