Cruz was once a human and is a former classmate and childhood friend of Louis. She is the girl that became the test subject of the Q.U.E.E.N. Project and is Gregorio Silva’s daughter.

Able to withstand the unimaginable pain from the experiments she chose to endure in order to save mankind, partly due to her caretaker Karen and her close friend Louis, she then became a powerful incarnate who even brought destruction on top of the Great Collapse. Despite her frenzy, she has somehow lost her senses, but still tries to reach out hoping someone would hear her plea.

The Protagonist is the one to "kill her", although she is described as "the immortal among immortals", and thus inherits her Blood Code and some of her abilities.

Cruz has long, white hair, reaching her until her hips and held up at the back of her head by what seem to be hair ornaments, and red eyes, which appear a vibrant shade blue after her frenzy.

She has a tan complexion, matching that of her father's and is seen wearing a blue surgical gown held up by black belt-like straps, dark grey stockings, white bandages on her lower arms and black gloves.

A scar is visible right above her heart.

Powers and Abilities Edit
Cruz is a skilled fighter, able to take on multiple people by her own as is seen when she fights both Jack and the Protagonist. She is also effectively immortal; her body has to be divided into the relics to keep her form reforming.

She is also the owner of multiple Blood Codes, such as:
Ishtar
Queen
Queen's Claw
Queen's Throat
Queen's Breath
Queen's Ribcage
