Diamond is extremely strong, and has the ability to transform herself into a crystalline statue: in this form she cannot be harmed - but it does have the drawback that she's unable to move.

The eldest of Maria and Julius Soliz' three children (the others being Samantha and Robert), Renata has black shoulder-length hair and dark brown eyes.

Although Renata is physically fourteen years old, she was born twenty-four years ago: during her first major mission - the final battle with Ragnarök - Renata was "frozen" into her diamond form, where she remained, unaging, until her awakening ten years later.
